Hey, dear astro friends. When should we expect the first science images from the Roman Space Telescope? I'm planning the 2027 planetarium show schedule, and I'm thinking of a Roman/Rubin survey telescope show. Any insight would be appreciated! 🔭 #astro

WE JUST GOT EMERGENCY TIME ON THE MEERKAT RADIO TELESCOPE TO LOOK TOMORROW AT THE CLOSEST SUPERNOVA IA IN OVER A DECADE!!! 🤩🥳📡 SN2026ahvu happened Nov 2 in NGC 1433, ~9Mpc (46mil light years) from us. Observations should probe the innermost regions around the SN and may reveal why it exploded! 🔭🧪

Mars may not be geologically dead after all. 🔴 Our ExoMars Trace Gas Orbiter has detected hydrogen chloride above volcanic fissures in the Alba Mons region, which scientists suggest could be linked to dormant volcanic activity beneath the surface. Read more: new.esa.int/articles/new...

I'm still paranoid about CA elections. Some of us are old enough to remember more GOP governors than DEM governors, and the Democratic party is waaaaaay too complacent here.

we've long known that Mars dust is much finer (in terms of particle size, not "fiiiiiine") than Earth dust, and this new study reinforces how dangerous that is to us. Mars is not Earth 2.0. It's Mars 1.0, its own world that evolved either with no life or co-evolved with life that can handle it.

The dust of Mars is “small enough to penetrate deep into pulmonary alveoli, bypass the blood–brain barrier, and threaten vital organs.” Hmm oh well. I guess we’d better phase out coal, oil, and “natural gas” after all. www.pnas.org/doi/10.1073/...

In honor of Sir Patrick Stewart 🫡🔭 I took a picture of Keid, the Home of Vulcan 🖖 This star is also known as 40 Eridani (home of Rocky from Project Hail Mary). The star is in the middle of the pic Thanks for inspiring us all 🙏 Taken with an 11" Celestron located in the Canary Islands.

I am lucky that I saw Patrick Stewart perform his solo "A Christmas Carol" twice many, many years ago when I was an undergraduate. I remember sitting in the theater and feeling as if I was witnessing something magical. Forever grateful for that feeling.

Just got a message from a witness in DC that a large plane flew extremely close to the ground a few minutes ago and scared the shit out of people. “Flashbacks to 9/11,” they said. AFP White House reporter Danny Kemp confirms it was a stunt for the WH halloween party and posted this video on X:
