The biomarkers and their stable isotopes show that methane was oxidized by aerobic bacteria, causing ocean acidification and CO2 emission from the Arctic Ocean during PETM. #PETM #IODP #biomarkers #methane #CO2

The Perseverance team discovered the rock formation in an ancient, now-dry riverbed in Jezero Crater, and instruments revealed that it's composed of clay and silt. On Earth, these are excellent preservers of past microbial life.

Want to hear about recent findings related returned samples from OSIRIS-REx and Hyabusa2? Consider joining the Workshop on Bennu and Ryugu Oct 7–9, 2025, at the Lunar and Planetary Institute in Houston, Texas (also virtual).

Finally, but but..?!

The upgrade allows Alvin to reach depths of up to 6,500 meters, surpassing its previous limit of 4,500 meters, and puts roughly 99% of the ocean floor at reach for research. https://t.co/UBsUcoMRXj Read more in the June issue of Eos:

With a suite of @NASA science and technology on board, @Firefly_Space is targeting no earlier than 3:34 a.m. EST on Sunday, March 2, to land the Blue Ghost lunar lander on the Moon. Live coverage will air on NASA+ around 75 minutes before touchdown >> https://t.co/7VZfUW0mjK

The Moon is so close, we can taste it! New footage from @Firefly_Space shows their lunar lander's view from 60 miles (100 km) above the Moon. Blue Ghost will land at Mare Crisium, on the near side of the Moon, on March 2, no earlier than 3:34am ET (0834 UTC).

Check out our Review on the Land-Ocean Arctic Carbon Cycle, out today in @NatRevEarthEnv co-led with my awesome partner in crime Micha Fritz from AWI!

Asteroid Bennu’s parent body was likely a salty, wet environment – one surprisingly like a lakebed on Earth. @NASA scientists drew similarities between a sample collected from Bennu by the #OSIRISREx mission & minerals from Searles Lake, a dry lake in California’s Mojave Desert.
