Black Holes: Dark Giants

By Josiah Sadnick-

Black Holes are one of the strongest forces in the galaxy! With a gravitational pull capable of pulling in any known object in the universe- the sun, planets, even light! A common unit of measurement is stellar masses and one stellar mass is the equivalent of our planet's sun. There are two main types of black holes- smaller stellar-mass black holes and far larger black holes the size of 100,000 to billions of solar masses! Also, Steller black holes are found wherever in the Milky Way while the bigger class black holes are only found in the center of some galaxies. Steller black holes are formed when a star, with at least 20 solar masses, exhausts its core and collapses as a result. A supernova explosion results that blows off all of the star's outer layers leaving just its core. If the core weighs 3 or more solar masses, the core proceeds to become a black hole. Still little is known about supermassive black holes and their origins. However, active development is being made towards learning about these wonders. In 2019, a group of astronomers using the "Event Horizon Telescope" captured not only a picture of a black hole but also a supermassive black hole for the first time(image on the post). Black holes are a beautiful powerful wonder of our galaxy.

NASA( https://www.nasa.gov/universe/what-are-black-holes/)is a great source to learn more about black holes and space in general.
