The quasi-periodic eruptions of X-rays from a black hole 300 million light-years away are unlike any researchers have ever ...

Extreme cosmic events such as colliding black holes or the explosions of stars can cause ripples in spacetime, so-called gravitational waves. Their discovery opened a new window into the universe. To ...

In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending ...

A herd of African elephants instinctively formed an "alert circle" to protect the younger elephants at the San Diego Zoo Safari Park as a 5.2-magnitude earthquake shook Southern California on Monday.

A mysterious black hole in a distant galaxy just woke up after decades of silence—and it’s putting on a cosmic light show! ESA’s XMM-Newton and other X-ray telescopes are capturing massive bursts of ...

"This rare event provides an opportunity for astronomers to observe a black hole's behavior in real time," said astronomer Lorena Hernández-García.

IT has long been known that some of the radio-elements emit a penetrating type of X-rays known as the gamma rays. It is clear that these radiations arising from the nucleus of the radioactive atom ...

It could point out environments with the right kind of black holes to produce the greatest number of planets without spraying them with X-rays. Life in such environments could emerge to its full ...
