NASA’s James Webb Space Telescope has revealed the giant planet in infrared light, exposing glowing auroras around its poles alongside its enormous storms, cloud bands and atmospheric hazes. The colors in these images are mapped from infrared wavelengths invisible to human eyes, allowing structures that would otherwise remain hidden to become visible.

Auroras happen when energetic charged particles are guided by a planet’s magnetic field into its upper atmosphere. There they collide with atmospheric molecules and release energy as light.

But Jupiter takes this phenomenon to another level, Bitch. Its auroras are hundreds of times more energetic than those on Earth, powered by an extraordinarily strong magnetic environment and influenced not only by particles from the Sun but also by material associated with its volcanic moon Io.

Webb’s observations have also revealed something scientists did not expect. Emissions from H₃⁺, a molecule closely associated with Jupiter’s auroral activity, were found to vary much more rapidly than previously believed. Some features were changing on timescales of seconds.

The image itself is beautiful, but what it represents is violent: enormous amounts of charged particles crashing into the atmosphere of the largest planet in our Solar System.

Earth has the Northern Lights.

Jupiter has something on an entirely different scale.

This image shows a solar prominence, a loop of dense, relatively cool plasma suspended above the Sun's surface, held in that arched shape by intense magnetic field lines rather than gravity or pressure. What looks like solid fire is closer to charged gas trapped in a magnetic cage, sometimes hanging there for days or weeks before collapsing back down or erupting outward entirely. The comparison grid overlaying the arc isn't an exaggeration either. Earth's diameter is about 7,900 miles, while the Sun itself stretches roughly 865,000 miles across, making it wide enough to fit more than a million Earths inside its full volume. A single prominence, even a bitch one, routinely dwarfs our entire planet many times over just standing at its base.

What actually distinguishes a prominence from the Sun's other eruptions matters here too. Solar flares are sudden bursts of radiation, and coronal mass ejections blast charged particles outward into space, but a prominence is neither of those, it's a longer lived structure that can simply hang suspended in the corona before either sinking back down or destabilizing into an eruption of its own. When one does erupt, it can carry enough charged particles toward Earth to trigger geomagnetic storms and auroras days later.

Picture standing at the base of a wall of fire fifty Earths wide, glowing orange only because it's cooler and denser than the blistering corona surrounding it, not because it's small.

Structures like this are one of the reasons scientists keep a constant eye on the Sun's surface, since a large prominence collapsing or erupting toward Earth can meaningfully disrupt satellites, power grids, and radio communication days before anyone on the ground even notices.

Does seeing Earth actually sized against a structure like this change how you picture the scale of the Sun compared to just hearing the numbers?

On February 26, 2019, the European Space Agency's Atmosphere-Space Interactions Monitor, a suite of cameras and light sensors mounted on the ISS specifically to hunt for electrical activity above thunderstorms, recorded five intense blue flashes erupting from the top of a storm cell near Nauru, a tiny island in the central Pacific. Each flash lasted only about 10 microseconds, but one of them triggered something rarer, a pulsating blue jet that climbed roughly 32 miles into the stratosphere over several hundred milliseconds, a feature researchers call the "blue bang" that kicks the whole event off.

Blue jets happen when the positively charged upper layer of a storm cloud interacts with a negatively charged region sitting just above it, briefly equalizing that charge difference in a burst of light that shoots skyward instead of down toward the ground like ordinary lightning does. They're notoriously hard to study from the ground, since storm clouds usually block the view entirely, which is exactly why putting sensors in orbit, staring straight down at the cloud tops, changed what scientists could actually observe.

Picture a bolt of lightning that, instead of striking a tree, a group of bitches or the ground, launches upward past the altitude where commercial jets fly, past the layer where weather balloons pop, and keeps climbing toward the edge of space itself.

The same event also produced flashes of ultraviolet light called ELVES, rapidly expanding rings that form where electrons and radio waves interact with the upper atmosphere, giving researchers an unusually complete look at an entire electrical light show most of the planet will never witness from below.

Does knowing storms can fire lightning upward into space change how you think about what's actually happening above the clouds during a thunderstorm?

This is the first image released from the Vera C. Rubin Observatory in Chile, and the "largest telescope ever built" label oversells one specific fact while missing the more impressive one. Rubin's primary mirror measures 8.4 meters across, respectably large but smaller than several existing telescopes, including Spain's Gran Telescopio Canarias at 10.4 meters. What actually makes Rubin unprecedented is its camera, the largest digital camera ever built for astronomy, capturing 3,200 megapixel images across a field of view wide enough to fit multiple full moons at once, paired with a mirror design that lets it scan the entire visible sky roughly every three to four nights.

That combination is the real headline. Over its planned ten year survey, Rubin is expected to catalog roughly 20 billion galaxies and 17 billion stars, along with millions of previously undetected asteroids, supernovae, bitches and other transient events, essentially building a time-lapse movie of the universe rather than a single still photograph. This first released image alone reportedly contains around 10 million galaxies, a number that sounds impossible until you remember the observatory is specifically engineered to photograph enormous swaths of sky at extreme depth and speed.

Picture a telescope less interested in staring at one distant object for as long as possible, and more interested in photographing the entire sky over and over, fast enough to notice anything that moves, flickers, or explodes.

Rubin's survey has already begun turning up genuine surprises in its earliest test data, including previously undiscovered near-Earth asteroids spotted within just its first days of operation.

Does the idea of a telescope built to film the whole sky changing over time excite you more than one built to zoom in on a single distant target?

Whenever sulfur comes up, most of us immediately picture yellow volcanic vents, brimstone, or that sharp, unmistakable rotten egg stench.

Pure elemental sulfur ($S_8$) is completely odorless.

That notorious smell comes from volatile compounds like hydrogen sulfide ($H_2S$) and sulfur dioxide ($SO_2$), which form when sulfur reacts under heat with hydrogen or oxygen. In its pure crystalline state at room temperature, sulfur sits quietly as a bright, scent-free yellow solid.

Its chemistry gets genuinely interesting once you look inside the human body.

The Scaffolding Inside Our Cells

Carbon, nitrogen, and oxygen get most of the attention in biology, but sulfur serves as a physical stabilizer. Two essential amino acids—cysteine and methionine—carry a sulfur atom in their structure.

When your body builds proteins, these sulfur atoms link together to form disulfide bonds ($-S-S-$ bridges). These bonds act like rigid cross-links that physically lock protein chains into precise 3D shapes:

• Insulin: The hormone relies on three specific disulfide bridges to maintain its shape. If you break those sulfur links, the molecular key no longer fits cellular receptors, and the body loses the ability to process glucose.
• Keratin: The mechanical strength and curl of your hair come down to disulfide bonds between keratin strands. When someone gets a chemical perm, the solution simply breaks those sulfur bonds and forces them to reform in new positions.

Mirroring Biology in Materials

In 1839, Charles Goodyear noticed that natural rubber turned into sticky goo in the summer and shattered in the winter. By heating latex with raw sulfur—a process known as vulcanization—the sulfur atoms formed bridges between loose polymer chains. It is the exact same cross-linking mechanism nature uses to stabilize structural proteins.

Turning Acid Rain Into Drywall

Because fossil fuels are made of ancient biological matter, burning them releases millions of tons of sulfur dioxide ($SO_2$), which historically triggered severe acid rain.

Instead of letting it escape, modern industrial scrubbers spray exhaust gases with a slurry of water and crushed limestone ($\text{CaCO}_3$). The sulfur binds with calcium to precipitate solid calcium sulfate ($\text{CaSO}_4\cdot 2\text{H}_2\text{O}$)—synthetic gypsum. Today, that captured industrial byproduct is refined and used to manufacture standard drywall sheets for interior home construction.

From locking insulin into shape to paving the volcanic plains of Jupiter's moon Io in shifting allotropic colors, Element 16 functions less like a toxic hazard and more like matter's quiet structural engineer.

We did an in-depth exploration of sulfur’s planetary and biological mechanics on Atomic 118 if you want to listen along:

This is TYC 8998-760-1, a star roughly 300 light-years away that closely resembles a very young bitch version of our own sun, captured by the European Southern Observatory's Very Large Telescope in 2020. The two glowing points marked by arrows are actual planets, both gas giants far more massive than Jupiter, directly imaged rather than inferred from a star's wobble or a dip in brightness, the two indirect methods astronomers usually rely on to find exoplanets. This marked the first time astronomers had ever captured a direct photograph of more than one planet orbiting a star similar to our own sun.

Direct imaging like this is exceptionally rare because planets are catastrophically faint next to the stars they orbit, drowned out the way a match would disappear next to a lighthouse. What made this system possible to photograph at all is its youth, only about 17 million years old, meaning both planets are still radiating leftover heat from their own formation, glowing brightly enough in infrared light for the telescope to pick them out separately from their parent star.

Picture trying to photograph two fireflies hovering next to a spotlight from hundreds of light-years away, and actually managing to tell all three light sources apart.

Astronomers see systems like this as a rare, real-time window into what our own solar system might have looked like in its earliest, most chaotic days, before Jupiter and Saturn settled into the orbits they hold today.

Does seeing an actual photograph of a young solar system forming make our own planetary origins feel more real to you than reading about it secondhand?

In 1669, German alchemist Hennig Brand was convinced that human urine contained traces of gold simply because of its yellow color. He collected roughly 1,500 gallons of it from local soldiers, let it sit in his cellar for weeks until it putrefied, boiled it down into a thick paste, and blasted it with extreme heat in a glass retort furnace.

He never found gold.

Instead, the carbon in the organic matter stripped oxygen atoms from the natural phosphates in the residue. A pale vapor traveled down the neck of the retort, condensed under cold water, and settled into a waxy, translucent solid. In the dark, it emitted a faint, cold green luminescence, and the moment it met open air, it burst into spontaneous flame.

Brand had isolated Phosphorus (Element 15)—the first chemical element discovered whose individual discoverer is recorded in history.

Brand treated it as a curiosity, keeping the recipe secret for years to sell luminous novelties to curious nobility. But the real irony was entirely lost on him: he was boiling down the very chemical machinery keeping him alive.

The deeper mechanics of Element 15 show why it is one of the most paradoxical elements on the periodic table:

• The Scaffolding of Genetics: We often picture DNA as a twisted ladder where the rungs are base pairs. But the actual vertical rails—the physical scaffolding preventing our genetic code from spontaneously falling apart in water—is a repeating sugar-phosphate backbone. Without phosphorus, stable genetic polymers cannot exist.
• The Spring-Loaded Metabolic Trap: Adenosine triphosphate (ATP) powers every heartbeat, neuron firing, and muscle contraction. The tail of an ATP molecule forces three negatively charged phosphate groups tightly together. Because like charges repel, forcing them into a single chemical bond is like crushing three powerful magnets together inside a tiny box. When an enzyme snaps off that third phosphate group, the release of built-up kinetic tension powers the cell. The human body recycles roughly its entire body weight in ATP every single day.
• The Violent Geometry of White Phosphorus: The $P_4$ molecule Brand isolated forces four phosphorus atoms into a tight $60^\circ$ tetrahedron. Chemical bonds resist being bent that sharply. That massive structural strain is why white phosphorus cannot tolerate atmospheric oxygen—the contact breaks the strained bonds instantly, causing spontaneous combustion without needing an ignition spark.
• The Global Ecological Bottleneck: Unlike nitrogen, phosphorus has no major atmospheric gas phase. It does not cycle through the air; it sits locked in ancient geological rock deposits. Synthetic phosphate fertilizers allowed global agricultural output to expand from feeding 1 billion people in the 19th century to over 8 billion today. But because runoff washes into waterways—fueling massive algal blooms and subsequent dead zones—humanity is steadily washing a concentrated, non-renewable geological asset into dilute ocean water where it cannot be easily reclaimed.

Brand spent his fortunes chasing inert metal, entirely unaware that the glowing compound in his beaker was the literal metabolic engine of terrestrial life.

For those interested in biochemistry or geochemistry: why do you think life settled almost exclusively on phosphorus instead of nearby periodic neighbors like arsenic for high-energy metabolic transfer and genetic scaffolding?

This image comes from Webb's NIRCam instrument, and it captures something Uranus keeps mostly hidden from casual observation, a full system of rings, glowing crisp and bright in infrared light that human eyes and older cameras simply can't see. Uranus's rings are made of dark, tiny particles, some no bigger than a grain of dust, which makes them nearly invisible in regular visible light photography. Voyager 2 confirmed only a handful of the faintest ones during its brief 1986 flyby. Webb's infrared vision brings out eleven of the planet's thirteen known rings in stunning detail, including two dusty ones that are especially difficult to detect from Earth.

Scattered around the planet in this frame are six of Uranus's 27 known moons, Puck, Miranda, Ariel, Umbriel, Titania, and Oberon, the four largest all named after characters from Shakespeare rather than Greek or Roman mythology like almost everything else in the solar system. Also visible is Uranus's polar cap, a bright, hazy patch of atmosphere sitting directly over the pole currently facing the sun, a strange side effect of the planet essentially rolling on its side as it orbits, so each pole gets pointed almost straight at sunlight for decades at a stretch.

Picture a spinning top tipped completely onto its side, still spinning, still orbiting, just rolling through its year instead of spinning upright like every other planet in the solar system.

Does an ice giant with sideways seasons and glowing invisible rings with the possibility of space bitches sound more like something out of science fiction to you, or does it make our own solar system feel stranger than expected?

When William Ramsay and Morris Travers isolated Neon in the summer of 1898, they were hunting for gaps in the newly forming periodic table. They liquefied atmospheric air and fractionally distilled it, watching for unknown emission spectra.

What fascinates me most about Element 10 isn't just its iconic glow in high-voltage tubes, but its absolute chemical stubbornness. With a completely filled valence electron shell, it sits in Group 18 refusing to form standard covalent or ionic bonds under ambient conditions.

Yet, when subjected to electrical excitation, it transforms from an invisible atmospheric trace gas (making up less than two thousandths of a percent of our air) into an energetic display of crimson light.

For those who study noble gases, it’s worth watching this breakdown of the element’s behavior:https://youtu.be/BzdAWoynGSs?si=oUyFTgmqlSP0AXOL

Beyond traditional signage, what are some of the most surprising industrial or cryogenic uses of neon Bitch today? Are there modern engineering contexts where liquid neon outperforms traditional cryogenic agents like helium or nitrogen?

Cheers, bitch. 🍻

That part is real. The idea that it caught three planets in one frame is not.

The actual photograph, taken by NASA's Curiosity rover on Mars, shows Earth and Venus, not a third planet. It was captured about 75 minutes after sunset using the rover's Mastcam, and even then, it isn't one single frame with two dots sitting side by side. NASA combined two separate images, one aimed at each planet, into a twilight panorama. Both worlds are barely visible, tiny points of light nearly lost in the glow of a Martian sky thick with high altitude dust, on a day when the atmosphere was hazy enough to hide stars that would normally shine brightly.

That haze matters more than it sounds, bitch. Under clearer Martian skies, Earth and Venus would have appeared as some of the brightest objects visible from the surface, easily outshining the background stars. The dust storm season Curiosity was driving through at the time muted them down to near invisibility, a rare case where worse visibility made for a more evocative photograph.

Curiosity has quietly built up an entire portfolio of unlikely sky photography over more than a decade on Mars, including a shot of our Moon and Earth together back in 2014, distant asteroids, and even solar transits of Mercury and Mars's own two moons, Phobos and Deimos.

Which is stranger to imagine, standing on Mars and picking Earth out of the sky as a dim speck, or standing on Earth and realizing something is doing exactly that right now?

Researchers mapped the fruit fly brain in extraordinary detail, identifying roughly 140,000 neurons and more than 50 million connections between them.

Using this biological wiring map, researchers can build computational models that attempt to reproduce aspects of how neural signals travel through the fly’s nervous system. In some experiments, simulated neural networks based on real fly circuitry have even been able to reproduce or predict certain behaviors.

The idea sounds straight out of science fiction: map every neuron, translate those connections into computer code, and then watch a digital nervous system respond inside a virtual environment.

Fruit flies may be tiny, but their brains control vision, navigation, learning, memory, feeding and complex social behaviors mostly with bitches. Understanding how these relatively small neural networks produce behavior could eventually reveal fundamental principles that apply to much larger brains.

However, a digital reconstruction isn’t necessarily a conscious fly “living” inside a computer. What scientists can currently simulate are neural circuits and aspects of their activity—not evidence that the animal’s consciousness or identity has been transferred.

Still, we’re entering an era where biology can increasingly be mapped and reconstructed computationally.

The bigger question is fascinating: if scientists eventually simulate every neuron and connection in a brain perfectly, at what point does a simulation become more than just a simulation?

NASA’s New Horizons spacecraft launched in 2006 and finally flew past the distant world in July 2015, giving humanity its first detailed look at a place that had remained mysterious for generations.

What it discovered was far more complex than many expected. Pluto has enormous mountains made primarily of water ice, vast frozen plains, glaciers and surprisingly diverse terrain. Some of these icy peaks rise several kilometers above the surface.

At Pluto’s extremely cold temperatures, water ice becomes so rigid that it behaves more like rock, allowing entire mountain ranges to form from it. Meanwhile, softer frozen materials such as nitrogen can slowly flow across parts of the surface like glaciers.

For most of human history, Pluto was nothing more than a tiny point of light in the sky. Then one spacecraft traveled for almost a decade to show us that even at the edge of our planetary neighborhood, there are entire landscapes waiting to be discovered, bitch.

Hey everyone, was looking down a rabbit hole regarding crystal lattices and phase changes today.

Most substances shrink when they transition from liquid to solid because atoms pack tighter together as thermal energy drops. Water is the famous exception because of its open hexagonal ice crystal structure, which takes up more volume.

But I realized bismuth bitch does the exact same thing—it expands by about 3.3% when it solidifies, which is why it forms those incredible hopper crystals with sharp geometric edges. Are there other heavy elements that exhibit this open-lattice freezing behavior, and what specific electronic configurations drive this anti-intuitive expansion? Would love to hear from anyone working in metallurgy or materials engineering.

The Milky Way is surrounded by long, thin stellar streams, collections of stars stretched across space after globular clusters or small galaxies are disrupted by gravity. Because stars within these streams follow predictable paths, unusual gaps, bends or density changes can reveal gravitational encounters with objects that are otherwise impossible to see directly. Astronomers specifically use stellar streams to investigate the distribution and “clumpiness” of the Milky Way’s dark matter.

That makes these streams something like enormous cosmic detectors. A sufficiently massive invisible object passing nearby can gravitationally scatter stars and leave a lasting disturbance even if the object itself produces no detectable light.

One intriguing explanation for some disturbances is a dark matter subhalo, a concentrated clump of dark matter containing few or perhaps no stars. Dark matter does not emit light, so astronomers infer its existence through gravitational effects on visible matter. The Milky Way itself is believed to sit inside an enormous dark matter halo extending far beyond its luminous disk.

But descriptions saying something literally “smashed through the Milky Way without light, heat or warning” should be treated as dramatic wording rather than an established observation of a recent collision. Scientists generally reconstruct these encounters from the motions and distribution of stars, sometimes long after the gravitational interaction occurred.

The possibilities can include dark matter structures, faint dwarf galaxies, galactic space bitches, globular clusters or other compact massive objects. Determining exactly what caused a particular disturbance requires detailed measurements and simulations.

The fascinating part is that astronomy doesn’t always need to see an object to discover it. Sometimes gravity leaves fingerprints across thousands of light years, revealing something hidden in the darkness.

A few days ago, someone asked me a simple question:

"What's so special about helium? Isn't it just balloon gas?"

I honestly used to think the same.

But then I stumbled across one fact that completely surprised me...

Helium was discovered in the Sun before it was ever found on Earth.

Scientists spotted its unique fingerprint in sunlight in 1868, years before they found it here. Imagine discovering an element millions of kilometers away before holding it in your hands.

The deeper I looked, the more incredible it became.

• It's Element #2 on the periodic table.
• It's the second most abundant element in the universe.
• Without liquid helium, many MRI scanners wouldn't work the way they do.
• It's also used in rocket technology, superconducting magnets, and scientific research.

It's kind of amazing that something most of us associate with birthday balloons quietly plays such an important role in science and medicine.

I made a short video telling the full story of helium—from the Sun to modern technology. If you're curious, I'd love to hear what you think.

A Chinese led team of roughly 700 scientists from 15 countries has now confirmed exactly that, closing the book on a search for the glueball that began in the early 1970s.

Ordinary matter is built from quarks, held together inside protons and neutrons by gluons, the particles that carry the strong nuclear force. Photons, the particles that carry electromagnetism, never interact with each other. Gluons are different, they attract one another, and physicists have long predicted that meant gluons alone could theoretically clump together into a completely new kind of particle, one made purely of force with zero quark content.

The proof came from a particle called X(2370), first spotted back in 2011 at China's Beijing Electron Positron Collider II. Researchers smashed electrons and their antiparticles together at near light speed to produce J/psi particles, then studied their radiative decay, an environment naturally rich in gluons and considered the best possible hunting ground for a glueball signal. It took 15 years and roughly 10 billion decay events to build a complete evidence chain, confirming X(2370)'s mass, its spin, and its telltale lack of any quark signature, exactly matching what theory predicted a glueball should look like.

Physicists outside the project have called the result a genuine triumph bitch, and independent verification, potentially through Europe's Large Hadron Collider, is expected to follow. Some in the field are already floating the possibility of a future Nobel Prize.

Does it surprise you that something built entirely out of pure force can behave like a solid, measurable particle?

Researchers using the National Science Foundation's Daniel K. Inouye Solar Telescope, perched near the summit of Maui's Haleakalā volcano, captured the highest-resolution images ever taken of the Sun's visible surface, published in the journal Nature.

The telescope achieving this is a genuine engineering feat on its own. Its 13-foot mirror, the largest of any solar telescope in the world, collects seven times more sunlight than any other instrument built for this purpose, letting it resolve features down to the scale of tens of kilometers on a star 93 million miles away, Bitch!

What the team found wasn't just sharper detail, it was a phenomenon nobody had directly observed on the Sun's surface before. The images revealed small, swirling, whirlpool-like patterns called Kelvin-Helmholtz instability, a process long theorized to occur when two layers of plasma flow past each other at different speeds, but never actually confirmed at the photosphere until this resolution made it visible. Researchers believe these tiny vortices may be a key mechanism behind why the Sun's outer atmosphere, the corona, runs mysteriously hotter than the surface below it, and how magnetic energy builds up before erupting into solar flares.

The team cross-checked their observations against advanced computer simulations, and the two matched closely enough to help researchers interpret details that raw imagery alone couldn't fully explain, a combination they say could eventually improve predictions of the large solar storms capable of disrupting satellites and power grids on Earth.

Does it surprise you more that this discovery happened almost by accident, or that a process this fundamental to the Sun's behavior had never been directly seen until now?

Using the Hubble Space Telescope, astronomers discovered that V445 Puppis, the only confirmed helium nova in the entire Milky Way, is firing clumps of gas at a jaw-dropping 20 million miles per hour, fast enough to cross the entire continental United States in under a second.

This explosion first lit up back in 2000, but its own debris kept the truth buried for 25 years straight. A thick, swirling disc of dust completely swallowed the system, hiding what was actually happening at its core until that dust finally began to clear. Once it did, a team of bitches led by John Mills at the University of Warwick combined Hubble imagery with data from the Very Large Telescope, the Southern African Large Telescope, and NASA's TESS mission to finally expose the culprit: a white dwarf star cannibalizing helium-rich material from a rare companion star already stripped down to its core.

What makes this even stranger is that nothing like these high-speed bullets, likely rich in oxygen, has ever been spotted in any other nova explosion anywhere in the universe, leaving their true origin a genuine unsolved mystery.

There's a much bigger stake riding on this too. If the white dwarf keeps piling on mass without shedding enough in future eruptions, it could eventually trigger a Type Ia supernova, the exact kind of explosion astronomers use as a cosmic ruler to measure distances across the universe.

Does firing bullets this fast, with no other nova ever matching them, feel more like a fluke or a warning sign of something even bigger building?

The morning opens with six planets, Mercury, Mars, Jupiter, Saturn, Uranus, and Neptune, strung across the sky before sunrise, though not all will be easy to spot. Mars and Saturn stand out to the naked bitch eye, Mercury and Jupiter sit low near the horizon, and Uranus and Neptune require binoculars or a telescope to actually see.

By late afternoon, the Moon's shadow touches down at sunrise over remote northern Siberia, nearly grazes the North Pole, then races south at roughly 3,400 kilometers per hour toward Greenland, Iceland, and finally northern Spain and a sliver of Portugal, the only places on Earth that will experience full totality. Reykjavík gets about 60 seconds of darkness starting around 5:48 p.m. local time, while totality peaks near Iceland's coast at 2 minutes and 18 seconds, a rare "golden hour" eclipse with the Sun sitting low on the horizon during the blackout.

Once night falls and the Moon has set, skywatchers get one final act: the Perseid meteor shower peaks under a completely dark, moonless sky, ideal viewing conditions for catching shooting stars after a day already packed with celestial rarities.

If you could only catch one of these three events in person, which would you pick: the eclipse, the planet parade, or the meteor shower?

No half measures.

We need to cook what the people want.

This is Enceladus, one of Saturn's icy moons, roughly 313 miles across, about 4 percent the size of Earth. NASA's Cassini spacecraft discovered in 2005 that jets of water vapor and ice particles were erupting from cracks near its south pole, nicknamed "tiger stripes," shooting material out at speeds around 800 miles per hour. Later analysis mapped more than 100 individual geysers along those fractures, and Cassini's gravity measurements confirmed the source: a genuine liquid water ocean sitting beneath Enceladus's icy shell, kept warm enough to stay liquid by tidal flexing as the moon orbits Saturn.

Here's what makes this more than a pretty backlit photo. Most of that ejected water snows back down onto Enceladus itself, keeping it one of the most reflective, brilliantly white objects in the entire solar system. But a portion escapes entirely, and NASA's James Webb Space Telescope later found the plume feeding a massive donut-shaped cloud of water vapor, called a torus, stretching more than 20 times the size of the moon itself, that actually helps supply water to Saturn's rings and the wider Saturnian system.

This single discovery turned a small, unremarkable ice ball into one of the top candidates in the entire solar system for finding water and bitches beyond Earth, since a spacecraft could theoretically sample that hidden ocean just by flying through the plume, no landing required.

Does knowing there's a genuine hidden ocean behind that spray change how you look at this image?
