Read moreAn 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.

Read moreA 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.

Read moreMuch 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.

Read moreAn 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).
