In 2024, someone identified what looked to be an impact crater located about 100 km north of Magpie, Quebec, as seen in this image from Google Earth. Researchers recently confirmed it was in fact a 390-million-year-old meteor crater — never before identified.

Born #OnThisDay in 1888 was seismologist and geophysicist Inge Lehmann ForMemRS. Lehmann is known for her 1936 discovery that the Earth's core must have a solid inner core inside a molten outer core. Before this, scientists believed that the core was a single molten sphere. #WomenInSTEM

🚀 Breakthrough on Mars! Mars Curiosity rover just discovered its most diverse collection of organic molecules yet. 7 of these 21 compounds have never been seen on the Red Planet before, proving Mars’ ancient chemistry was even more complex than we thought. #Mars #NASA #SpaceExploration 1/4
NASA’s Curiosity Mars rover took this selfie on Oct. 25, 2020, after drilling a rock sample from a spot nicknamed “Mary Anning.” After years of extensive analysis, the sample has revealed the greatest diversity of organic molecules ever found on Mars.

The FY 2027 NASA budget request hides its science cuts by omitting mission names instead of explicitly zeroing them out. We did the work and found 54 missions cancelled in this proposal. This is another extinction-level event for NASA science. Full list: planetary.org/save-nasa-science

👨‍🚀 The #Artemis II crew are now further from home than any humans ever, and European engines brought them there 🚀. 🌍 The record of 400 171 km was previously held by the Apollo 13 mission 🌕.
(April 6, 2026) In this fully illuminated view of the Moon, the near side (the hemisphere we see from Earth), is visible on the right. It is identifiable by the dark splotches that cover its surface. These are ancient lava flows from a time early in the Moon’s history when it was volcanically active. The large crater west of the lava flows is Orientale basin, a nearly 600-mile-wide crater that straddles the Moon’s near and far sides. Orientale's left half is not visible from Earth, but in this image we have a full view of the crater. Everything to the left of the crater is the far side, the hemisphere we don’t get to see from Earth because the Moon rotates on its axis at the same rate that it orbits round us.

☄️ Right in the middle of Europe lies a 25 km-wide impact crater left by an asteroid 15 million years ago – today it hosts an entire town. 👩‍🚀 @esa.int’s PANGAEA training brings astronauts to the Ries impact crater in Germany to teach them to read the geological stories written in stone. #AsteroidDay
The Copernicus Sentinel-2 mission captured an area in southern Germany, where approximately 15 million years ago an asteroid crashed through Earth’s atmosphere. The high-speed impact formed what is now known as the Ries crater.Astronauts and planetary geologists gather around intriguing rocks at the Ries crater in southern Germany.

Mars on the cover of the new issue of Science Featuring a photograph taken by the Curiosity rover at the Ubajara drill site. Credit: NASA/JPL-Caltech/MSSS www.science.org/toc/science/... 🧪🔭 #Mars
The cover of Science Magazine, dated 18 April 2025, featuring a photograph of Gale crater, Mars, taken by the Curiosity rover at the Ubajara drill site. The rover’s 40-cm-wide tracks are visible in the foreground. The rover drilled a rock sample at this location, which was found to contain substantial amounts of siderite, an iron carbonate mineral. The siderite likely played a role in an ancient carbon cycle that affected Mars’ surface climate. Main title of the cover reads "Carbonates on Mars" with subtitle reading "Evidence of an ancient carbon cycle".
