China completes world's largest solar telescope array with a whopping 313 dishes https://www.space.com/china-completes-giant-radio-telescope-array-solar-observation
Omg the FCC *actually* responded to our astronomer concerns about Starlink??? I’m in shock. We stopped the full megaconstellation disaster from destroying the sky. They’ve approved *less than one third* of the satellites.
@sundogplanets we did it!! - for now? Astronomical thank you to Dr. Lawrence!! https://mastodon.social/@jfoust/109440614175364963
RIP to Christine McVie, who may have been the lowest-profile of Fleetwood Mac's songwriters, but may also have been my favorite.
The International Astronomical Union's Center for the Protection of the Dark and Quiet Sky from Satellite Constellation statement on the AST SpaceMobile BlueWalker 3 satellite and potential impacts to astronomy: "BlueWalker 3 is a big shift in the constellation satellite issue and should give us all reason to pause." #BW3

#Introduction: Welcome to the #CMSexperiment! 😎
CMS stands for Compact Muon Solenoid 🧲.
It is a big collaboration involving more than 5000 #physicists, #engineers, #technicians, and #students from across the world. The CMS detector act as a huge camera 📸 designed specifically to record what’s happening when the #LHC at #CERN provides proton-proton or heavy ion collisions. ⚛️
Stay with us to #explore the secrets of #particlephysics!
It remains way past time to stop letting corporations unilaterally make a mess of the sky.
Elon Musk’s Starlink and other satellite sources of light pollution and orbital debris should face an environmental review, the U.S. Government Accountability Office finds https://bit.ly/3icjpQc
Rant on satellite constellations #SatCons
It's interesting how many of the large #satellite constellations are named after famous astronomers or #astronomy objects: Beidou, Galaxy, Galileo, Kepler, Kosmos, Kuiper. Yet they will have a huge impact on amateur and professional #astronomy. And I don't think, that is beautiful. Rather a slap in your face... 😟
New metric prefixes needed because we make too much data!
The prefixes ronna and quetta represent 10^27 and 10^30, and ronto and quecto signify 10^−27 and 10^−30. Earth weighs around one ronnagram, and an electron’s mass is about one quectogram.
This is the first update to the prefix system since 1991, when zetta (10^21), zepto (10^−21), yotta (10^24) and yocto (10^−24) appeared. Peta and exa were added in 1975.

I don't think I'm ready to eat out at a restaurant, which will make this a bit different than a pre-covid conference trip that involved lots of science discussion and socializing over meals - but as a parent/professor/farmer, ordering take-out and eating it all alone in my hotel room while doing nothing at all productive sounds ABSOLUTELY LUXURIOUS, and I don't think I'll ever get to do that if I don't go.
So... I really hope my body fights this off effectively by tomorrow!
