Dinosaurs Washed Away in Largest Wave to Wrap Earth
As if getting set on fire and tossed into space wasn’t enough, new research finds evidence that after the Chicxulub impact, dinosaurs were also the victims of a massive global tsunami and worldwide earthquakes. Plus, the Milky Way’s stellar graveyard, a new timeline for the Moon’s formation, and this week in space history, we look back at the Meteosat program.

How to Build a Supervolcano in Just Four Million Years
Using pockets of gas found in tiny crystals, scientists have created a timeline for the formation and eruption of four supervolcano events in northern Chile more than twenty million years ago. Plus, rocket launches, gorgeous new space images, and an interview with Jian-Yang Li about the upcoming DART mission’s impact.
Water Worlds May Hide Water Underground
A population study of 43 exoplanets orbiting M-dwarf stars used both the transit method and radial velocity method to find the densities of the worlds and a surprising pattern emerged. The planets are less dense than expected, suggesting they are not purely rock but half-rock and maybe half-water. Plus, star factories in the Milky Way, glaciers on ancient Mars, and This Week in Space History.
Climate Change Melts Glaciers, Greens the Arctic
As global temperatures rise, Earth observations show that glaciers are retreating and ice sheets are melting everywhere from Greenland to Antarctica while regions of the Arctic are getting greener. Plus, collaborations lead to new Mars and exoplanet discoveries, several rockets launched, and this week’s What’s Up involves Dr. Brian May of Queen.
SEASON PREMIERE: Catching up on news and rockets!
As we return from our summer hiatus, we are back with a rundown of some of the stories that came out during the break. On the planetary front, JWST has been taking amazing images and learning about exoplanets. On the astrophysics front, we’ve got stories on dark matter and Betelgeuse. And there were thirty orbital launches, including a whole lot of Starlinks… but not including Artemis.
Machine Learning Pinpoints Martian Meteorite Origin
Using layers of data from a variety of Martian missions, researchers have developed a machine learning algorithm that identified the actual crater from which a particular Martian meteorite originated. Plus, a radio heartbeat, and our last What’s Up and review of the season.
All the Rockets and All the Rocks
With the release of JWST’s first science images behind us, we now catch up on all the rocket launches of the past few days. Meanwhile, Bennu continues to be a favorite research topic and is the subject of three new papers released this week. Plus, pulsar-orbiting planets, and this week in rocket history, we look back at GEOTAIL.
