#PPOD: Artemis II Commander Reid Wiseman took this picture of Earth from the Orion spacecraft’s window after completing the translunar injection burn. There are two auroras (top right/bottom left) and zodiacal light (bottom right) visible as the Earth eclipses the Sun. Credit: NASA/Reid Wiseman 🧪 🔭

Photo of Earth seen from the Orion spacecraft, with green aurora to the upper right and lower left and bright white zodiacal light at the bottom right. The Earth is lit by moonshine, and Africa can be seen on the left. Clouds swirls throughout the circle.

Interesting #astromethods paper came out recently that looks at whether or not large language models can replicate astrophysics papers. The answer: No. 🔭☄️ They had a ~20% replication score, even with quite a lot of help. And this was just replicating papers - not doing anything new...

ReplicationBench: Can AI Agents Replicate Astrophysics Research Papers?

Frontier AI agents show increasing promise as scientific research assistants, and may eventually be useful for extended, open-ended research workflows. However, in order to use agents for novel resear...

Today's reading begins with Lise Meitner, who co-discovered nuclear fission (she wrote the paper!) and was in general an INCREDIBLE trailblazing scientist. Except, as a Jew, she had to flee Nazi Germany to Sweden and lost her professorship in Berlin. The men she worked with got the prize instead 🧪🔭

Okay, now that I can stop talking with all caps, why is this important? So, we're looking for planets like Earth, right? It's the only place we've found with life so far. What makes it "Earth"? Well, some things include being a rocky planet, and being the right temperature for liquid water. (1/N)

After nearly a decade of saying which JWST result I was most excited about, it's here: JWST SPECTRA OF THE HABITABLE TRAPPIST-1 PLANETS! TRAPPIST-1 E!!! IT'S ... A FLAT LINE! BUT NOT AS FLAT AS IT COULD BE!? IS THERE AN ATMOSPHERE?!?!? WE STILL DON'T KNOWWWWW. www.nytimes.com/2025/09/08/s...

Kepler mission: smaller stars have more short-period, small #exoplanets. Theory: the smallest stars won’t have enough disk material to make small planets so there must be a turnover. Kepler+K2: We have found a turnover! Check out our newest Scaling K2 paper: arxiv.org/abs/2508.05734 🧵 1/9 🔭🧪☄️

Scaling K2 VIII: Short-Period Sub-Neptune Occurrence Rates Peak Around Early-Type M Dwarfs

We uniformly combined data from the NASA Kepler and K2 missions to compute planet occurrence rates across the entire FGK and M dwarf stellar range. The K2 mission, driven by targets selected by guest ...

ALMA found evidence for complex organic compounds, such as sugars & amino acids, in a protoplanetary disc. Thus, discs may inherit these complex molecules from interstellar clouds. More in this press release by @mpi-astro.bsky.social : https://www.mpia.de/news/science/2025-05-v881-ori 🔭 🧪

The evolution of life may have its origins in outer space

Astronomers find complex organic molecules – precursors to sugars and amino acids – in a planet-forming disc.
