Spewing supermassive black hole (SBH) in the Milky Way!
As cold gas spirals inward, some of it get superhot and 'spews' out in jets.💦 Till now, the SBH in our galaxy showed no signs of spewing. (Ewww). HT to ALMA & Chandra for finding 1st signs of gentle jets. 🔭🧪

Pt.2: The most accurate measures of a black hole's mass come from observing masers -- natural radio sources. So, this may be less precise, but what's a few million solar masses among friends?
'Little Red Dots' underwhelming name for overwhelming cosmic critter!
#JWST lurching toward cosmic dawn 'weighs' ginormous black hole, adding evidence that primordial black holes 'collapsed' into existance rather than assembled from lesser objects.🔭🧪

The cleverly named 😏 "Very Long Baseline Array" (VLBA) is freakin' amazing but seldom ballyhooed.
10 radio dishes spanning Hawai'i to St. Croix. Resolution akin to spotting penny in Paris from NYC. Latest? Using quasar 10 bly away to map interstellar weather.🔭🧪

I take this personally! (And so should you.)
I've seen my shadow by the light of the Milky Way, the LMC over San Pedro de Atacama, Venus shadow at Kitt Peak...
Have you ever looked up to see the Milky Way and said "WOW?" No? It may be now or never.

Freakin' Amazing Radio Camera!! 📡
Caltech's DSA. 1,650 dishes.
Data rate = entire US internt traffic!
Camera aspect will use GPUs to turn data tsunami into pictures in real time!
World's most sensitive radio telescope: The "PhotoMart" of the radio universe!🧪🔭

Mosquitos love me! 🦟 A lot, and the welts last for days.
One frontline defense, DEET, may lose efficacy if mosquitos learn to associate the smell with a tasty meal. #science
They can learn?! We’re doomed.

A Black Hole Star? Supporting evidence is growing!
iopscience.iop.org/article/10.3...
1.8 billions years post big bang (a toddler on the cosmic scale), a black hole is gobbling up fuel and growing fast! Light from near the BH gets tweeked by a cocoon of gas, the hallmark of the monster within.🧪🔭
How do blobs of cosmic dust and gas flatten into planet-forming disks?
The ALMA telescope and ‘maths’ reveal that a tenuous transition zone gradually shepherds matter into the familiar disk-like (Keplerian) motion of our & other solar systems. 🔭🧪 #science #space

Where there’s clay, there was water. And life is rather fond of water. 💧
@esa.int ExoMars (launching 2028) will have a ginormous swathe of the Red Planet’s surface (300x600 km) to ‘play in the clay’ & search for signs of past (?) life! #astrobiology 🧪🔭
