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.
Next week, Discovery News will be participating in the Convergence conference -- a meeting of some of the greatest physics minds on the planet.
Astronomers have witnessed, for the first time, a relativistic collision in a black hole jet millions of light-years from Earth.
Astronomers have zoomed into an X-ray emission region immediately surrounding our galaxy's supermassive black hole and stumbled on a mysterious place where stars go to die.
The Event Horizon Telescope (EHT) now spans the diameter of our planet and, when the vast project goes online, astronomers will get their first glimpse of the bright ring surrounding a supermassive black hole.
