'Vanishing' stars may be turning into black holes without going supernova, new study hints
By Keith Cooper published
Stars that vanish from the sky may be collapsing directly into black holes without going supernova first, a new study of a bizarre binary star system suggests.

Space photo of the week: Hubble spots a twisted 'train-wreck' galaxy that may hide a cosmic illusion
By Jamie Carter published
The Hubble Space Telescope's stunning image of the dusty 'train-wreck' galaxy NGC 4753 reveals what may be one of the greatest optical illusions in the nearby universe.

The universe may be dominated by particles that break causality and move faster than light, new paper suggests
By Paul Sutter published
With the nature of the universe's two most elusive components up for debate, physicists have proposed a radical idea: Invisible particles called tachyons, which break causality and move faster than light, may dominate the cosmos.

James Webb telescope finds origins of the biggest explosion since the Big Bang — revealing a new cosmological mystery
By Ben Turner published
Seen in 2022, a gamma-ray burst nicknamed the BOAT is believed to be the brightest explosion ever witnessed by humanity. But the James Webb Telescope's search for its origins has only thrown up more questions.

Betelgeuse's mysterious spin could be a cosmic illusion caused by its enormous 'boiling' surface
By Harry Baker published
The gigantic star Betelgeuse, which could be close to exploding, has previously been seen spinning much faster than it should be. However, a new study suggests that these observations were misinterpreted because of the star's shape-shifting surface.

Dead star with 'metal scar' on its face likely killed and ate a planet in our galaxy, study finds
By Ben Turner published
A "metal scar" spotted on the face of a white dwarf star called WD 0816-310 could be the remains of a destroyed planet, researchers say.

Astronomers discover 25 'stripped stars' that may be a missing link in supernova science
By Robert Lea published
The discovery of stars with their outer layers of hydrogen stripped by companions fills a glaring hole in our understanding of supernovas and binary systems with colliding neutron stars.
