Astronomers have mapped the 'disk winds' associated with the accretion disk around Hercules X-1, a system in which a neutron star is drawing material away from a sun-like star. The findings may offer clues to how supermassive black holes shape entire galaxies.

This supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000-light-year-long 'contrail' of newborn stars, twice the diameter of our Milky Way galaxy.

Astronomers have made an unexpected and rare discovery: a pair of gravitationally bound quasars, both blazing away inside two merging galaxies. They existed when the universe was just 3 billion years old.

An international team of astrophysicists and cosmologists have submitted a set of five papers, measuring a value for the 'clumpiness' of the universe's dark matter, known to cosmologists as S8, of 0.76, which aligns with values that other gravitational lensing surveys have found in looking at the relatively recent universe - but it does not align with the value of 0.83 derived from the Cosmic Microwave Background.

A head-on collision between the two galaxies UGC 12914 (left) and UGC 12915 (right) 25-30 million years ago appears to have resulted in a different kind of structure - a bridge of highly turbulent material spanning the two galaxies. Though this intergalactic bridge is teeming with star-forming material, its turbulent nature is suppressing star formation.

Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds - high-powered streams of charged particles and gases - can change the chemical make-up of the host galaxies they form in, simply by blowing in a specific direction.

An international team of researchers has used the James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI).

Researchers have found a neutron star that captures matter from a companion star in a violent and unstable process. This process, previously observed only in very bright black holes, opens the door to new insights into the behaviour of stars.

Astrophysicists have leveraged artificial intelligence to uncover a better way to estimate the mass of colossal clusters of galaxies. The AI discovered that by just adding a simple term to an existing equation, scientists can produce far better mass estimates than they previously had.
