This composite image of the Medusa galaxy (also known as NGC 4194) shows X-ray data from NASA's Chandra X-ray Observatory in blue and optical light from the Hubble Space Telescope in orange. Located above the center of the galaxy and seen in the optical data, the "hair" of the Medusa -- made of snakes in the Greek myth -- is a tidal tail formed by a collision between galaxies. The bright X-ray source found towards the left side of Medusa's hair is a black hole.

Medusa Galaxy

Most bright X-ray sources in galaxies are binaries containing either stellar mass black holes or neutron stars that remain after the supernova explosion of a massive star. Because these compact objects can generate X-rays for much longer periods of time than the lifetime of their massive progenitor stars, X-ray binaries may be used as "fossils" to study the star formation history of their host galaxies. In this Medusa image, the X-ray binaries are seen as the bright blue point-like objects.

Wow! This looks awesome. Can we even imagine the nuclear force that is released during this explosion, could it destroy a planet? All thanks to NASA, they are a group of intelligent people discovering the galaxies & their stars.


It was also found that for

It was also found that for every one million tons of gas that goes into making stars, one ton gets pulled onto a stellar mass black hole or a neutron star. This result may help create more accurate models of the formation of X-ray binaries.


Black Hole.

Every Galaxy has a black-hole in it's centre and it can not be seen directly. The above image is a way to see a black-hole indirectly.
