Sagittarius A*, the supermassive black hole of the Milky Way, is hungry for some croissant 🥐

Methuselah

One of the oldest stars, if not the oldest star, ever observed. It is projected to have an age of ~13.7 billion years. For reference, the age of the universe is also a value of ~13.7 billion years (give or take many millions of years).

Sagittarius A*

Of course it counts as a star, there’s a star right in the name (*)! Sagittarius A* is the supermassive black hole in the center of the Milky Way. We all orbit it. Black holes are one of the many end stages a star’s life can lead towards, but because of its huge size, Sagittarius A* most likely was never a star at all. Still though, we like to bend the rules a bit.

This is BIG NEWS guys. Huge news. All galaxies have black holes, btw. We aren't special on the account. But getting a photo of ours? Now that, that is special.

Oohs and aahs broke out at the National Press Club in Washington when Feryal Ozel of the University of Arizona displayed what she called “the first direct image of the gentle giant in the center of our galaxy.” She added: “It seems that black holes like doughnuts.”

Everyone say hi to  Sagittarius A*, the black hole at the center of our galaxy

Im in love with the fact that the team Event Horizon took a picture of something that has an escape speed faster than light and just went

It's so crazy

COMIC - Cosmic Mysteries: Black Holes

(Heliosphere: Under the Sky is an original solar system project with personified stars and planets)

Space facts!

Black holes are mysterious. They are huge concentrations of matter packed into very tiny spaces.

A black hole is so dense that gravity just beneath its surface, the event horizon, is strong enough that nothing - not even light - can escape.

Black holes can be stellar or supermassive.

However, continued studies propose intermediate (middle ground mass), primordial (formed with the universe), and ultramassive (in the case of TON 618).

The supermassive (edit: not superlative) black hole at the center of our galaxy (right & bottom) has finally been imaged! Top pic is simulations of the first black hole ever imaged (much larger) compared to Sagittarius A (smaller so it moves faster)

This is the actual image of Sagittarius A

Images taken (screen shotted) from the press conference at ESO earlier this morning.

“An image of the supermassive black hole at the heart of the Milky Way has been captured, giving the first direct glimpse of the “gentle giant” at the centre of our galaxy.The black hole itself, known as Sagittarius A*, cannot be seen because no light or matter can escape its gravitational grip. But its shadow is traced out by a glowing, fuzzy ring of light and matter that is swirling on the precipice at close to the speed of light.The image was captured by the Event Horizon telescope (EHT), a network of eight radio telescopes spanning locations from Antarctica to Spain and Chile, which produced the first image of a black hole in a galaxy called Messier 87 in 2019.

Sagittarius A* is consuming only a trickle of material, in contrast to the typical depiction of black holes as violent, ravenous monsters of the cosmos. “If SgrA* were a person, it would only consume a single grain of rice every million years,” said Michael Johnson of the Harvard-Smithsonian Center for Astrophysics.

M87*, by contrast, is one of the largest black holes in the universe and features vast, powerful jets that launch light and matter from its poles into intergalactic space.

The EHT picks up radiation emitted by particles within the accretion disc that are heated to billions of degrees as they orbit the black hole before plunging into the central vortex. The blotchy halo in the image shows light bent by the powerful gravity of the black hole, which is 4m times more massive than that of our sun.

Ultimately, scientists hope that observing a range of black holes – fairly dormant ones like our own and turbulent giants like M87* – could help answer a chicken-and-egg style question about the evolution of galaxies.

“It’s an open question in galactic formation and evolution. We don’t know which came first, the galaxy or black hole,” said Prof Carole Mundell, an astrophysicist at the University of Bath who is not part of the EHT collaboration.

What will happen to the black holes at the centers of both the Andromeda and Milky Way galaxies once they collide?

[The Gayle/Chris Fleming Meme reading: okay, was anybody going to tell me that astronomers just unveiled pictures of a black hole in the center of the Milky way Or was I just supposed to read about it in an article about free Krispy Kreme donuts myself.]
