Black Hole Sun

If you're as fascinated by astronomy as I am, you'll find this latest discovery interesting. A study by German astronomers has confirmed that the core of our Milky Way galaxy is a super-massive black hole, located about 27,000 light years from Earth and approximately 4 million times heavier than the Sun. A black hole forms when a star has depleted its fuel source to the point where it cannot maintain combustion, which causes it to collapse into itself under its own gravity due to its incredible mass. While already generally accepted as fact by the scientific community, the existence of black holes was technically theoretical, and this study appears to provide empirical proof. It was believed that large black holes centered most, if not all, galaxies in the universe. We now know that's also true, at least for one galaxy. Read more about black holes here.
