A sudden X-ray flare from a supermassive black hole in galaxy NGC 3783 triggered ultra-fast winds racing outward at a fifth the speed of light—an event never witnessed before. Using XMM-Newton and ...

Deep in the frozen heart of Antarctica, the South Pole Telescope has been watching one of the most extreme neighborhoods in our galaxy, and it's just caught something extraordinary happening there.

A supermassive black hole has astonished astronomers after it was observed blasting out powerful winds raging at roughly one-fifth the speed of light. Two X-ray observatories, the European Space ...

Astronomers have detected a supermassive black hole flare thought to be the brightest and most distant discovered yet. Credit: Caltech / R. Hurt illustration A supermassive black hole tearing apart a ...

A star’s fatal brush with a supermassive black hole can light up a quiet galaxy. When gravity shreds the star, its gas spirals inward and briefly glows. Astronomers call these flares tidal disruption ...

Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to ...

A supermassive black hole in the spiral galaxy NGC 3783 just delivered an X-ray surprise that astronomers have never watched unfold so quickly. Using the European Space Agency’s XMM-Newton and the ...
