I know this is lowbrow but seeing the photos from a new story of a raccoon that trashed a liquor store and passed out in its bathroom has me LOL. This raccoon has it going on.

I love this study 🧪, because I really think people are in general more empathic than we give them credit for!

How timely! Looks like EHT has just decided on an acronym for their upcoming run:
Just finished our winter (online) @ehtelescope.bsky.social Collaboration meeting today, and someone came up with the awesome acronym for our Spring 2026 first ever #blackhole MOVIE campaign = "Multi-epoch Observations with VLBI of the Intensity Evolution of M87*"!! 🧪🔭⚫🎬

On the way up to #ALMA around 4000m we had to make way for one of the two massive telescope dish transporters, “Otto”. It weighs 130 tons and can lift 110 ton telescope dishes to reconfigure the array! 🔭🧪

Woke up to some unexpected good news today in the Netherlands: the centre-left party D66 won over the far right who were the lead party last election. Big sigh of relief. Also means: don’t listen to the polls.
