I did catch them in 2002 (a while ago) yet recall seeing one every 10 seconds or so. Some were remarkably bright. I have yet to see a comparable shower, but hoping this might be the year.
Get ready for one of the very best meteor showers of the year! The Geminids are great and this year's show over the weekend should be excellent.
Also: a gorgeous star cluster with a dramatic swirl of stars.

ALMA discovery in 2015 popped up in my OneDrive feed. Still amazing! Einstein ring -- massive foreground galaxy focusing light from more distant galaxy to reveal details never before seen in a galaxy so remote, including phenomenally massive yet concentrated clumps of star-forming material. 🧪🔭

ALMA is so cool! Well, it does observe the cold universe. Here’s a glimpse of what the Sun will look like a few billion years hence. 🧪🔭
ALMA has captured extremely detailed radio images of the turbulent atmosphere of a dying star 📡 🌟
It observed tens of molecular spectral lines, each one revealing a different atmospheric layer.

A brilliant story by @astrokimcartier.bsky.social! In Romeo and Juliet, Mab is the 'fairies' midwife,' delivering dreams and shaping fantasies. In planetary geology, she's equally mischievous, inspiring scientists' dreams about another rendezvous with Uranus. 🧪🔭

Some advice when talking to science deniers:
Be nice, it’s unexpected.
Be calm, don’t feed outrage porn.
Listen, you won’t change their mind about science, but you might change their mind about you.
Don’t rise to the bait of “then how do you explain?” It’s fishing for unsatisfactory relies. 🧪

Is there ever a shred of evidence that the assassination/murder of 11 humans (not bound for the U.S.) was justifiable under ever the most tenuous and oblique interpretation of national security? Just another abomination and abuse of power for Republicans to shrug off as they worship plutocracy.
I'm pressing Trump for answers about the summary killing of 11 people on a boat in the Caribbean by the U.S. military. It's critical to our security and the safety of our servicemembers that we get information about what happened and why, and who exactly was killed.

Ever wonder what two merging black holes look like? Here's the clearest signal that LIGO has ever measured, of two black holes that were each approximately 33 times as massive as the Sun. The merger converted 5% of that mass into gravitational radiation — stretching and squeezing of spacetime. 🧪
