A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...

Exceptionally powerful X-ray jets have been detected emanating from two supermassive black holes. These cosmic structures ...

But the supermassive black holes are just one candidate for a source of the massive gravitational hum. "We found the choir, but we don't know who's singing in it — the pop stars are the ...

Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions seen since the Big Bang.

The Hubble Space Telescope has imaged a "200,000 light-year-long trail of newborn stars" that may have been left behind by a runaway supermassive black hole. Video Credit: Black Hole Animation ...

First up is WR 124, a type of star called a Wolf-Rayet which is a potential precursor to a black hole. As these old, massive stars come to the end of their lives, they start throwing off layers of ...

For the first time, astronomers have confirmed the existence of a lone black hole — one with no star orbiting it. It’s “the only one so far,” says Kailash Sahu, an astronomer at the Space ...

How dark is dark? When you go outside on a clear, moonless night, you can see not only lots of stars but also the black space between them—literally space, in this case.

The "gravitational lens" effect magnified that star's light, shifting its position in space as well. The black hole passed the star in 2011, the researchers explain, but the star's position is ...

These stars fling their outer layers out into space, ... this nebula is heard as flutes and the background stars as bells. ... either a neutron star or a black hole.

A 15-year search reveals the first evidence of a cosmic 'gravitational wave background' emitted by ancient, colliding black holes. When you purchase through links on our site, we may earn an ...

This is seen, for instance, where black holes or neutron stars are in a close orbit such as this. In February 2016, gravitational waves were detected for the first time, 100 years after Einstein ...
