Another #BlackHoleFriday weekend #GravitationalWave candidate #S241201ac

If real, the source is probably a binary black hole. Virgo glitches may impact source inference

Here is a cinematic version of a black hole with our hero plunging in past the event horizon, beyond which even light cannot escape the gargantuan gravity of the black hole.

Nobel laureate Kip Thorne was the scientific consultant and an executive producer for the movie Interstellar.

It's the day after Thanksgiving. Which means it is #BlackHoleFriday!

Let's start with this stunning visualization from NASA of a supermassive black hole similar to the one at the center of our galaxy.

A flat, swirling cloud of hot, glowing gas called an accretion disk surrounds the black hole. So do glowing structures called photon rings, which form closer to the black hole from light that has orbited it one or more times.

I've read a lot of books about black holes. Some have more impressive illustrations/visual aids than others.

While this particular book doesn't have the most impressive visual aids, it does a marvelous job of describing the fundamental unit of information; the bit, contained within the smallest scale possible, the Planck length.

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!!

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

Image from me and the Event Horizon Telescope collaboration.

Some of the brightest objects in space are blazars—supermassive black holes feeding off material, which can create two powerful jets of high-speed particles.

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

A black hole's gravity is so powerful that not even light can escape it. 😱

But on this #BlackHoleFriday, we ask you not to fear the mysterious things in our universe and instead be open to their beauty.

It's #BlackHoleFriday!!! Here's a thread about black holes from me, your friendly internet astronomer 😊

Thirty years ago, @nasa 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
#Hubble

today is #blackholefriday , and I show you a collection of #blackhole s I have painted over the recent years.

This black hole is on the move!

Hubble found evidence of an isolated black hole roaming around the Milky Way.

It's estimated that there are about 100 million black holes like this that are drifting through our galaxy: https://go.nasa.gov/3icsjx4

Happy #BlackHoleFriday!

The 1st widely accepted black hole, Cygnus X-1, was discovered decades earlier in 1964. X-rays emitted were detected by a pair of Geiger counters launched on a sounding rocket from White Sands Missile Range in New Mexico. #BlackHoleFriday

Gas glows brightly in this computer simulation of supermassive black holes only 40 orbits from merging. Models like this may eventually help scientists pinpoint real examples of these powerful binary systems.

Happy #BlackHoleFriday! Earlier this year, @NSF scientists obtained the first image of a black hole — a feat not possible w/o Katie Bouman, an @EHTelescope scientist who led the development of an algorithm used during the processing of the historic image. https://www.jpl.nasa.gov/edu/news/2019/4/19/how-scientists-captured-the-first-image-of-a-black-hole/?utm_source=TWITTER&utm_medium=WomenNASA&utm_campaign=NASASocial&linkId=77746337 

Feel like you're throwing your money into a black hole?

Take a break from #BlackFriday — celebrate #BlackHoleFriday with us and get sucked into this recent discovery of a black hole that may have sparked star births across multiple galaxies:

Some black holes are feasting, but the one at the heart of our Milky Way galaxy is starving.

Magnetic fields appear to be sending material into an orbit around the black hole, not into it, preventing it from ingesting very much. https://www.nasa.gov/feature/magnetic-field-may-be-keeping-milky-way-s-black-hole-quiet?utm_source=TWITTER&utm_medium=SOFIAtelescope&utm_campaign=NASASocial&linkId=77831925  #BlackHoleFriday
