“Don’t call it a Substack”
Substack isn’t your friend. Substack is trying to work you into a place where they can squeeze you. You are the frog in the slowly boiling water.

Fantastic work by Ariel Graykowski and our @setiinstitute.bsky.social citizen scientists.
Comet C/2025 K1 (ATLAS) is breaking apart — and some of you caught it live. After passing 0.3 AU from the Sun, it erupted, and three days later a third appeared.
K1 is now officially in pieces.

Wouldn't you and your institution rather keep your grant funds to spend on research than hand it over - directly or indirectly - to publishers? I know I would!

We looked for an atmosphere on TRAPPIST-1d using JWST, but we didn't see any atmospheric absorption.
So TRAPPIST-1d is quite different from Earth, despite lying just inside the habitable zone. The planet is either:
➡️ A bare rock.
➡️ Very cloudy.
➡️ Has a thin, Mars-like atmosphere.

The TRAPPIST-1 d exoplanet may be Earth-sized 🌍 but it has no Earth-like atmosphere.
Webb’s #NIRSpec has found no traces of molecules that are common in Earth’s atmosphere.

This is a solar eclipse.
Seen from the surface of Mars by the Perseverance rover in 2022.
That moon is the little space potato Phobos. And you can even see sunspots!

After reporting the news, games media must now grapple with what the call to boycott Xbox means for us. I wrote about why we must and how we can orient games writing towards liberation. Games nor words alone will save us, but we can as individuals express solidarity and possibility in all we do.

Our VLT has found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars.
This is the first time we have strong evidence for one of these ‘polar planets’ orbiting a stellar pair 😲
