Papers published in Astronomy & Astrophysics and the Astrophysical Journal suggest astrophysicists need to update their theories on how galaxies evolve.

A team using the Dark Energy Spectroscopic Instrument (DESI) and a supercomputer to try to better understand the mysterious phenomenon known as dark energy, created the largest 3D map of the universe as part of this endeavour. And it has just made this map publicly available.

The Andromeda Galaxy…is surrounded by a swarm of nearly 3 dozen dwarf galaxies, which circle it like bees around a hive. These “satellite galaxies” have been studied in unprecedented detail in a new paper published in the Astrophysical Journal.

Water may have first formed 100–200 million years after the Big Bang, according to a modeling paper published in Nature Astronomy. The authors suggest that the formation of water may have occurred in the universe earlier than previously thought and may have been a key constituent of the first galaxies.

Its ruddy complexion is the defining characteristic of Mars, the idiosyncrasy that marks it out from all the other planets of the Solar System. But a new study suggests we may have misunderstood the mechanism whereby its rouge was obtained. The research has been published in Nature Communications.

A very rare treat is about to grace Earth’s night skies. On the evening of 28 February 2025, all seven of the other planets in the Solar System will appear in the night sky at the same time, with Saturn, Mercury, Neptune, Venus, Uranus, Jupiter, and Mars all lining up in a neat row – a magnificent sky feast for the eyes known as a great planetary alignment.

Advanced artificial intelligence is to revolutionise fundamental physics and could open a window on to the fate of the universe, according to Cern’s next director general.

The idea of lightsails is something out of science fiction. As early as the 1950s and ‘60s, science fiction writers John Campbell, Arthur C. Clarke and others were toying with the idea of “solar sails” for spacecraft propulsion…Project researchers report in a paper published in Nature Photonics that they have developed a platform to test the materials that could one day form lightsails.

Scientists have found all five nucelobases alongisde minerals essential for life as we know it on the potentially hazardous asteroid Bennu. The two teams of researchers who made the discoveries published their findings Jan. 29 in two papers in the journal Nature Astronomy.

A new study reveals that what lies beneath the lunar surface may be more dynamic than previously believed.

As described in a study published in the Astrophysical Journal Letters, researchers have collected further evidence of 2024 PT5 being of local origin: It appears to be composed of rock broken off from the moon’s surface and ejected into space after a large impact.

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.

NASA’s Curiosity Rover has been exploring Mars since 2012 and more recently has found evidence of ice-free ancient ponds and lakes on the surface. The rover found small undulations like those seen in sandy lakebeds on Earth.

On the evening of 28 February 2025, all seven of the other planets in the Solar System will appear in the night sky at the same time, with Saturn, Mercury, Neptune, Venus, Uranus, Jupiter, and Mars all lining up in a neat row – a magnificent sky feast for the eyes known as a great planetary alignment.

In the distant space out beyond the orbit of Jupiter lurks a strange object. Its name is Chiron, a type of outer Solar System body known as a centaur. But even among its fellow centaurs, Chiron is special – and new observations from JWST reveal how truly Chiron is like nothing else we’ve ever seen.

There might not be a mysterious ‘dark’ force accelerating the expansion of the Universe after all. The truth could be much stranger – bubbles of space where time passes at drastically different rates.
