Astronomers have witnessed for the first time a violent cosmic collision in which one galaxy pierces another with intense radiation. Their results show that this radiation dampens the wounded galaxy's ability to form new ...
Astronomers searching for massive black holes shredding stars found one in an unusual place -- 2,600 light years from the core of a galaxy. The roque black hole may be from an earlier merger with another galaxy, or have been tossed out of the core ...
A new study achieves unprecedented accuracy in modelling extreme cosmic events like black hole and neutron star collisions by calculating the fifth post-Minkowskian (5PM) order, crucial for interpreting gravitational wave data from current and ...
The universe is decaying much faster than thought. This is shown by calculations of scientists on the so-called Hawking radiation. They calculate that the last stellar remnants take about 10^78 years (a 1 with 78 zeros) to perish. That is much ...

Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities, i.e. points where the laws of physics break down. Identifying ...

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the ...

In 2018, a galaxy about 270 million light-years away from Earth exhibited a major increase in activity. It quieted down again by 2020 -- only to dramatically increase its output again in 2023. At ...

Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant ...

The night sky has always played a crucial role in navigation, from early ocean crossings to modern GPS. Besides stars, the United States Navy uses quasars as beacons. Quasars are distant galaxies ...

Astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the black hole's ...

Scientists have spotted a massive black hole in the early universe that is 'napping' after stuffing itself with too much food. Like a bear gorging itself on salmon before hibernating for ...

After taking the first images of black holes, the groundbreaking Event Horizon Telescope (EHT) is poised to reveal how black holes launch powerful jets into space. Now, a research team has shown that ...

An international team of researchers has detected a binary star orbiting close to Sagittarius A*, the supermassive black hole at the centre of our galaxy. It is the first time a stellar pair has been ...

The galaxy M87, located in the Virgo constellation, provided the first-ever photo of a black hole in 2019, when the Event Horizon Telescope captured an image of the supermassive black hole at the ...

Could a decades-long debate about the mysterious movements of stars in Omega Centauri, the largest star cluster in the Milky Way, finally be ...

A theoretical study suggests that small black holes born in the early universe may have left behind hollow planetoids and microscopic tunnels, and that we should start looking within rocks and old ...

Scientists using observations from NASA's Neil Gehrels Swift Observatory have discovered, for the first time, the signal from a pair of monster black holes disrupting a cloud of gas in the ...

Researchers have developed an innovative technique to search for black hole light echoes. Their novel method, which will make it easier for the mass and the spin of black holes to be measured, ...

The temperature of elementary particles has been observed in the radioactive glow following the collision of two neutron stars and the birth of a black hole. This has, for the first time, made it ...

Astronomers have discovered a supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang that is consuming matter at a phenomenal rate -- over 40 times the ...

Researchers have strengthened the case that matter becomes dark energy when massive stars collapse and become black ...

Researchers have pored over more than two decades' worth of data from NASA's Chandra X-Ray Observatory to show there's new knotty science to discover around black ...

A surprising discovery about the black hole V404 Cygnus is expanding our understanding of black holes, the objects they can host, and the way they ...

Astronomers observed ancient quasars that appear to be surprisingly alone in the early universe. The findings challenge physicists' understanding of how such luminous objects could have formed ...
