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 →
For the first time, three supermassive black holes have been discovered in a tight orbital dance inside the center of a galaxy 4 billion light-years away. Continue reading →
Although we have a pretty good idea that our galaxy contains a supermassive black hole at its core, there could be another — albeit rather exotic — explanation for our observations of Sagittarius A*. It might be a wormhole. This … Continue reading →
Conventional thinking suggests that the most massive black holes possess a ringed doughnut-shaped torus of gas and dust trapped in orbit around them. But if we know one thing about black holes, they're anything but conventional. Continue reading →
If you happened to be falling into a black hole, the last thing on your mind will likely be how pretty the view is. Continue reading →
News about black holes is usually accompanied by some fun description of them eating stuff. But the supermassive behemoth at the center of NGC 253 has become a little... sleepy. Continue reading →
With the help of NASA's brand new NuSTAR observatory, astronomers have measured the spin of a supermassive black hole by detecting the relativistic effects that warp space-time at the edge of its event horizon.
