It has long been assumed that the size of a supermassive black hole in a galaxy's core is intimately related to the number of stars that galaxy contains -- but it might not be that simple.
Are you ready to get "spaghettified"? Julian has the gooey, stretchy, bizarro physics behind a human's leap into a supermassive black hole.
A surprisingly massive black hole has been discovered in the core of a small, compact galaxy -- a finding that appears to be a weird cosmic contradiction.
Quasars are the brightest objects in the universe, and display a mysterious diversity in their appearance that has puzzled astronomers for more than two decades.
Astrophysicists have analyzed two decades-worth of X-ray data and discovered three events inside galactic cores that can be interpreted in only one way: stellar destruction. Continue reading →
In 2011, astronomers were getting excited for what promised to be a spectacular cosmic event. Sadly, it looks like it's turned out to be a galactic damp squib. Continue reading →
As part of an ongoing survey of active galaxies, the Hubble Space Telescope looked deep into the heart of one stunning example just 32 million light-years from the Milky Way. Continue reading →
