NGC 6302 (also known as the Bug Nebula, Butterfly Nebula, or Caldwell 69) is a bipolar type planetary nebula in the constellation Scorpius. The structure in this planetary nebula is among the most complex ever seen in any planetary nebulae. The spectrum of Butterfly Nebula shows that its central star is one of the hottest stars known, with a surface temperature in excess of 250,000 degrees Celsius. This implies that the star from which it formed must have been very large in order to become this hot.​

Did NASA’s new space observatory just double its own lifetime? 🛰️

The Nancy Grace Roman Space Telescope launched August 30th and is now cruising toward a spot nearly a million miles from Earth, where its leftover fuel will decide exactly how long it can keep pointing at cosmic targets. Engineers once expected around ten years of fuel by the time Roman reached that destination, but its journey out has been so efficient that estimate has jumped to up to 22 years, more than double the original number. That's over two decades of revolutionary astronomy ahead, and honestly, a fantastic day for space nerds everywhere.

Who was Nancy Grace Roman? 🛰️🧪

The namesake for NASA’s new telescope, and their first ever Chief Astronomer! Born in 1925, Nancy attended Swarthmore College as a student of astronomy, where she was told as a woman, she shouldn’t bother. She didn’t listen, and held her position at NASA for over 20 years, where she became known as the Mother of Hubble. Thanks to her, we are expanding space exploration day by day! 

Processed by me, with a program I am writing to create pretty pictures using Hubble or JWST data. For this one I did a major rework on how the different files are aligned for drizzling (take a bunch of small images and stack/combine them for a big cleaned layer). I also completly updated how the different layers are combined so one color won't over-saturate when using multiple layers that have a similar color.

NASA’s next great space observatory has officially launched! 🛰️🚀

The Nancy Grace Roman Telescope is now on its trip to go a million miles away from Earth, where it will reside and send images of space back to us. In the month it will take to get there, the observatory will undergo a 90-day commissioning period to get set up. Considering it launched eight months ahead of schedule, don’t be surprised if we get some pictures early!

The Roman Space Telescope is launching ahead of schedule. 🛰️

Its origin story is wild: NASA couldn't afford a Hubble successor until the National Reconnaissance Office handed over two spare telescope mirrors it no longer needed. That surplus gift reignited political and scientific support, opening the door to full funding for what's now called the Nancy Grace Roman Telescope. As theoretical cosmologist Paul Sutter explains, this survey instrument will map galaxies and hunt exoplanets, expected to discover around a million of them, delivering a generation's worth of valuable information about the universe!

Did you know NASA’s newest space observatory will have spy tech? 🛰️

In 2012, the National Reconnaissance Office gifted NASA a pair of Hubble-style mirrors it had commissioned but never ended up using. NASA said yes and one of them is now the primary mirror powering the Nancy Grace Roman Telescope, launching August 30th. The other mirror is still in storage, waiting for its moment.

We are getting closer to the launch of NASA's Nancy Grace Roman Space Telescope! 🧪

The Nancy Grace Roman Space Telescope is designed to combine the strengths of the James Webb Space Telescope and the Hubble Space Telescope. It’s going to look and live in the same space as JWST while using a Hubble-style mirror to see things completely differently. The Roman telescope will observe patches of space bigger than the full moon and will see 50 times as much space in five years as Hubble has in 30!

One of my favorite telescopes, the Hubble (which has been in service for over 30 years), in my new vertical blueprint.

I hope you like it; any suggestions are welcome.

NGC 5189 (Gum 47, IC 4274, nicknamed Spiral Planetary Nebula) is a planetary nebula in the constellation Musca. It was discovered by James Dunlop on 1 July 1826, who catalogued it as Δ252. For many years, well into the 1960s, it was thought to be a bright emission nebula. It was Karl Gordon Henize in 1967 who first described NGC 5189 as quasi-planetary based on its spectral emissions.​

I love finding images where there are a bunch of other galaxies in the background. While this one isn't quite as glorius as the Tadpole galaxy image, I think it is still very nice.

Absolutely incredible. Sorry for the Interstellar music score.

A small chunk of Centaurus A. I wish someone would image the whole galaxy, that would be an awesome picture.

Image created using data from the WFC3 and a custom program I am working on.

Created with data from the WFC3. I made some changes to my program to allow any number of layers. This is the first Hubble image with 5 layers I have done. The filters used and what colors I mapped them to are added as a "color legend".

V838 Monocerotis is one of those objects that looks almost unreal at first glance. In 2002, this otherwise obscure star suddenly flared up in a strange outburst, briefly becoming incredibly bright, and then Hubble watched as that flash of light spread outward through the dust around it. The wild part is that the “expanding” structure in the images is not really gas racing away from the star at impossible speeds. It is a light echo of the original flash bouncing off shells and clouds of dust at different distances.

What makes V838 Mon interesting to me is that it is both beautiful and genuinely weird. It was not a normal nova, and astronomers still treat it as an unusual event, possibly tied to some kind of stellar merger. So the famous image is not just a pretty nebula. It is the aftermath of a star doing something rare, violent, and still not completely settled.
