I am sharing this 'as-is' the original fediverse post text is quoted below along with a link to the article.

A pair of X-ray telescopes have observed the messy aftermath of a star that came too close to a supermassive black hole 290 million light-years away. It's believed that the star had three times the mass of the Sun, so this was one of the largest tidal disruption events ever seen. Although the black hole consumed some of the star, most of its guts were thrown into the surrounding space, polluting the region with the chemicals that allowed astronomers to estimate its stellar mass.

So following on from the post on December 1st this is a quick review of the active galaxies lecture from the Space Telescope Science Institute.

This lecture, presented by Dr Mitchell Revalski, is really interesting, looking at how supermassive black holes, despite their small size compared to the galaxy they reside in.

Energy from these can push away surrounding gas, and heat this up which reduces star formation as gas needs to cool to form stars.

so scales are pretty huge:

First lets look at what a light year is

Citation : spaceplace.nasa.gov

For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!

1 pc = 1 parsec = 3.26 light years

Supermassive black hole < 1pc

Bulge = 1 = 3 kpc (kilo parsec)

disk 30 kpc

circumgalactic area 50kpc

So even though these black holes are very small, they have a big influence on what surrounds them.

We know this is happening thanks to the research that led to the 2020 Nobel prize.

Well worth watching and the link is above.
