Is Earth inside a giant void? It could solve one of cosmology's biggest puzzles
By Indranil Banik published
Our best observations can't come up with a single answer for how quickly the universe is expanding. Maybe that's because our galaxy is at the center of a giant void.
Earth slammed by ultra-powerful 'goddess particle' cosmic ray, and we have no idea where it came from
By Harry Baker published
Researchers recently detected an "ultra-high-energy" cosmic ray, which is the most powerful since the famous "Oh My God" particle was detected in 1991. They have no idea where it came from.
Dark matter may have its own 'invisible' periodic table of elements
By Paul Sutter published
Dark matter may come in multiple particles and weights, similar to the ordinary elements on the periodic table, a new theory suggests.
'Rogue' star hurtling through the Milky Way won't smash into our solar system after all
By Robert Lea published
A white dwarf spotted by the Gaia telescope was predicted to smash into our solar system in 29,000 years. But we'll be safe after all.
Largest-ever simulation of the universe reveals 'shortcomings' in standard model of cosmology
By Sharmila Kuthunur published
Scientists made a twin version of our universe, showing the evolution of all forms of matter and energy, in the biggest cosmological computer simulation to date.
'Remarkable' explosions from colliding, dead stars could reveal the true expansion rate of the universe
By Robert Lea published
Two conflicting methods to measure the expansion rate of the universe give different results, but researchers could resolve the disparity by watching merging neutron stars explode.
James Webb telescope's observations of 'impossible' galaxies at the dawn of time may finally have an explanation
By Ben Turner published
A new set of simulations suggests that the unusual brightness of early galaxies discovered by the James Webb telescope could be because of a strange, rapid-burst mode of star formation.
Ancient supernova in James Webb telescope image could help solve one of the universe's biggest mysteries
By Harry Baker published
NASA's James Webb Space Telescope has spotted a distant supernova that appears three times in the same photo. The new observations could help solve one of the universe's biggest inconsistencies.
Nuclear 'pasta' cooked up by dead stars could unravel the secrets of stellar afterlife
By Paul Sutter published
In the extreme hearts of neutron stars, fundamental particles are twisted into strange 'pasta' shapes that could reveal untold secrets about how dead stars evolve.
$100,000 Breakthrough physics prize awarded to 3 scientists who study the large scale structure of the universe
By Ben Turner published
Mikhail Ivanov, Oliver Philcox, and Marko Simonović won the New Horizons Award for their work on large scale structures — the strands and filaments of our universe which contain buried clues to its most fundamental properties.
