For the first time, scientists have proof two supermassive black holes exist together in the same galaxy, thanks to data from NASA’s Chandra X-ray Observatory. These black holes are orbiting each other and will merge several hundred million years from now, to create an even larger black hole resulting in a catastrophic event that will unleash intense radiation and gravitational waves.
GalaxyZoo is a project which harnesses the power of the internet – and your brain – to classify a million galaxies. By taking part, you’ll not only be contributing to scientific research, but you’ll view parts of the Universe that literally no-one has ever seen before and get a sense of the glorious diversity of galaxies that pepper the sky.
Our galaxy’s supermassive black hole is responsible for the mysterious gamma-ray emission from the galactic center, a new study suggests. Churning magnetic fields around the monster black hole may act like a giant particle accelerator, leading to high-speed collisions that produce the gamma rays.
Like cold case investigators, astronomers have used NASA’s Chandra X-ray Observatory to uncover evidence of a powerful outburst from the giant black hole at the Milky Way’s center. Astronomers believe a mass equivalent to the planet Mercury was devoured by the black hole about 50 years earlier, causing an X-ray outburst
