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. Astronomers have detected ...
Last year, astronomers were fascinated by a runaway asteroid passing through our solar system from somewhere far beyond. It was moving at around 68 kilometers per second, just over double Earth's speed around the sun.
When astronomers look out into the cosmos, they see supermassive black holes (SMBH) in two different states. In one state, they're dormant. They're actively accreting only a tiny amount of matter and emit only faint, weak ...
Some galaxies eject powerful streams of charged particles—jets—from their centers into space. The prominent jet of Messier 87 (M87) in the constellation Virgo is visible over distances of 3,000 light-years and can be observed ...
An international research team led by scientists at Waseda University and Tohoku University has discovered an extraordinary quasar in the early universe that hosts one of the fastest-growing supermassive black holes known ...
It's one of astronomy's great mysteries: how did black holes get so big, so massive, so quickly. An answer to this cosmic conundrum has now been provided by researchers at Ireland's Maynooth University (MU) and reported today ...
Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies. To observe distant black holes clearly, multiple radio telescopes must capture cosmic signals ...
One of the most vivid portraits of "reborn" black hole activity—likened to the eruption of a "cosmic volcano" spreading almost 1 million light-years across space—has been captured in a gigantic radio galaxy.
What we know of the birth of a black hole has traditionally aligned with our perception of black holes themselves: dark, mysterious, and eerily quiet, despite their mass and influence. Stellar-mass black holes are born from ...
Astronomers at the University of Warwick have discovered that black holes don't just consume matter—they manage it, choosing whether to blast it into space as high-speed jets or sweep it away in vast winds.
