The European Space Agency said that the black hole inside the spiral galaxy NGC 3783 has the mass of 30 million suns.

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 ...

Learn more about the supermassive black hole in galaxy NGC 3783 and how its powerful blast is similar to our sun’s coronal ...

X-ray space telescopes spotted a never-seen-before blast from a supermassive black hole. The post Black hole’s winds going ...

Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their physical existence. One theory suggests that these ...

How confusing inevitability with reality built decades of paradox. What if general relativity never actually tells us that ...

Two clashing ideas about disorder inside black holes now point to the same strange conclusions, and it could reshape the ...

NASA has visualized the cataclysm, which is thought to have caused a mysterious eruption of gamma rays captured by telescopes ...

"We were amazed by the fact that these observatories can detect about 100 black holes just 250 million years after the Big Bang. Such detections would greatly help to constrain black hole formation ...

The Event Horizon Telescope — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. EHT researchers ...

"Our findings pave the way for rigorous examinations of black holes and the exploration of new physics in gravity." Cosmic echoes from some of the universe's most violent collisions are far more ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...
