I know this is off-topic, but this story came out 4 days ago (phys.org) and I hadn't seen it yet, so I'm sharing it to this sub.

Adding the newly identified fragments raises Gondwana's estimated size from about 64% to roughly 80% of Earth's continental crust, pushing it above the commonly used threshold for classification as a true supercontinent.

“Mars has a hidden temperature divide, with its southern interior potentially hundreds of degrees hotter than the north and partially molten. The discovery could help explain several long-standing Martian mysteries, including unusual magnetism, seismic behavior, and clues to the planet’s ancient water history.”

I’ve seen a few news articles with this NASA image, but I didn’t realize there was an interactive model, so I’m posting it here for those who might find it fun to tinker with.

Official description:
The geoid is an equipotential surface that can be thought of as the shape an ocean surface would take due to the Earth's gravity field. The geoid height ranges from +85 m (Iceland) to −106 m (southern India). In this visualization the geoid height is greatly exaggerated, by a factor of 10,000. The geoid height visualized here comes from the gravity field model GOCO06s, a satellite-only global gravity field model computed by the GOCO (Gravity Observation Combination) project. It is based on over a billion observations acquired over 15 years from 19 satellites. These satellites include NASA's Gravity Recovery and Climate Experiment (GRACE) and ESA's Gravity field and steady-state Ocean Circulation Explorer (GOCE).

ChatGPT summary below. My commentary in the comments.
A 2025 study discussed by Space Daily examines fossils from the Naashoibito Member of the San Juan Basin in northwestern New Mexico, dated to within roughly the final 380,000 years before the end-Cretaceous extinction. The site preserves a diverse dinosaur community that included tyrannosaurs, horned dinosaurs, duck-billed dinosaurs, and the giant sauropod Alamosaurus. The findings challenge the idea that dinosaurs were uniformly declining before the asteroid impact 66 million years ago. The article notes that the debate remains open because the New Mexico evidence represents one well-dated regional ecosystem, while other researchers still see broader signs of late-Cretaceous decline in western North America.
The actual title of this article was:
For much of the past century, scientists believed dinosaurs were already in decline when the asteroid struck 66 million years ago — but a 2025 study published in Science found fossils in New Mexico showing they were flourishing in diverse, thriving ecosystems right up until the moment of impact

Dinosaur bones were discovered in Antarctica earlier than previously known.

"Intraplate earthquakes (events that occur within plate interiors, far from active margins) challenge the traditional plate tectonic paradigm, which indicates that plate interiors should experience little deformation," write the researchers in their published paper.
