Yeah could be a technological luminescent deflector shield. He is setting back SETI research at this point unfortunately.

Signs of the times in science.

New paper out! This is a review of the published JWST observations of rocky exoplanets so far: arxiv.org/abs/2507.00933

Quick summary of the key points:

Astronomers may have just discovered the third interstellar object passing through the Solar System!

ESA’s Planetary Defenders are observing the object, provisionally known as #A11pl3Z, right now using telescopes around the world.

Rumors or any sources yet?

NASA begins mass firings of scientists ahead of Trump team’s deadline Top advisers in the Office of the Chief Scientist are among the first to go amid downsizing effort.

One of the employees fired from NASA told me how much their career meant to them: "Prior to everything happening today, NASA has been an incredible place to work — to dream big, to innovate, to do things that I never thought I could have done.”

Words by me. 🧪

Critical mass of professional scientists? Seems that way.

Informal astro-poll: who else is delinquent on grant reports besides me? One, it's not a fun activity but understandably necessary; two a lot of PIs/faculty are already overloaded with work; three the process is not entirely streamlined.

Nasa says distant exoplanet could have rare water ocean and possible hint of life Space agency said potential finding of dimethyl sulfide on K2-18 b, produced only by life on Earth, is yet to be confirmed

Exoplanet news! Astronomers have used #JWST to peer into the atmosphere of K2-18 b, a planet with a size and mass that could mean an ocean world with a gaseous atmosphere.

They found a potential hint of dimethyl sulfide, which you might not have heard of, but is only formed by life here on Earth. 👀

This looks just like a simpler version of the OG twitter!
