#ArtAdventCalendar - Day 9. Anyone for one of the most awesome things in our universe? It’s Black Hole Friday and I’ve created a digital artwork of a Black Hole from a digital representation, using Adobe Fresco on iPad Pro, from my Circles Portfolio. #sciart #DigitalArt #astronomy #BlackHoleFriday #science

15/ Finally, I'm far from the only black hole expert on fedi! 🤩 I've lost track of how many other astronomers have joined recently, but please reply here with your latest and/or coolest black hole-related research!!

Black hole anatomy diagram from NASA, simulation from J. Schnittman.

Still recovering from #blackholefriday.

13/ By the way, professional astronomers, how many intermediate-mass black hole discoveries/results do you mostly-to-definitely trust? 🧐

Feel free to elaborate in the replies (though plz don't be shitty to people by name), and please boost this so more astros see it!

9/ We even have a supermassive black hole at the center of our Milky Way galaxy! It's name is Sgr A* ("Sagittarius A-star") and it's about 4 million solar masses, which makes it medium-sized in supermassive black hole terms.

The Event Horizon Telescope took a picture of it in radio light last year, and it is such a gorgeous lumpy orange donut 🤩 #OurBlackHole #blackHoles #BlackHoleFriday #astronomy #astrophysics #space

Weighing in at about 4 million times the mass of our Sun and located roughly 26,000 light-years from the best (and worst) #BlackFriday deal going today is our favorite black hole, Sagittarius A* — the supermassive black hole at the center of our galaxy. Happy #BlackHoleFriday!⚫

A 5-for-1 #BlackHoleFriday deal? Shown here is Stephan's Quintet. While the five galaxies are the focal point, this Webb image also reveals outflows driven by a supermassive black hole in one of the galaxies in never-before-seen detail: https://go.nasa.gov/3F4Fvgy

While black holes don’t emit light, their influence can be seen. Swirling gas, energetic jets, and even ripples in space-time give them away. Follow this thread to learn how different observatories help us study black holes! #BlackHoleFriday

Material around black hole V404 Cygni produces bursts of X-rays that reflect off clouds of gas and dust like headlights in fog. This new sonification of @chandraxray@twitter.com and Swift data translates these light echoes into a stunning soundscape: https://s.si.edu/sonify6 #BlackHoleFriday

Material surrounding a #BlackHole can produce intense bursts of electromagnetic radiation that can bounce off clouds of gas & dust in space like a headlight in the fog. Our new sonification turns these “light echoes” from a black hole into sound. #BlackHoleFriday ⚫

Thirty years ago, @NASA@twitter.com released this extraordinary Hubble image of a gas and dust disk fueling a galaxy’s black hole.

Hubble observations helped provide evidence that most galaxies contain enormous black holes: https://go.nasa.gov/3ieuBMc

I love black holes. My videos often feature new black hole findings. They're one reason I was drawn to astronomy. I even studied black-hole-powered galaxies for my PhD.

So, in honor of #BlackHoleFriday, I'm going to share some of my previous black hole themed videos.
