Like a blinding beacon lighting up the night, a powerful gamma-ray-generating stellar husk has been seen pulsating in a neighboring galaxy.
Scientists are taking initial steps in a long-term effort to learn as much as they can about gravitational waves -- mysterious undulations in the fabric of space-time that have so far evaded clear detection.
After undergoing a 5-year upgrade, the world's most powerful gravitational wave detector is back online and hunting for the tiniest of tiny fluctuations in spacetime.
Astronomers have discovered the smallest supermassive black hole lurking in the center of a dwarf galaxy around 340 million light-years away. Small it may be, but it could help to unlock some pretty hefty black hole mysteries.
As spotted by NASA's Chandra X-ray Observatory, a binary star system 7,500 light-years away has undergone a violent stellar wrecking ball event.
A newfound giant black hole nearly as massive as 7 billion suns is dozens of times larger than astronomers expected given its host galaxy's size, researchers say.
The Event Horizon Telescope (EHT) has added more observatories to its global network of radio telescopes and the first image of our galaxy's black hole could be less than a year away.
The prospect of measuring the mass of the most massive known objects in the universe would send most people into a cold sweat, but for astronomers it's all in a day's work.
