The Viewpoint: New research casts doubt on ‘impossible’ signals from Antarctica
After a dedicated search found no evidence of exotic particles traveling through the planet, the mystery of Antarctica's "impossible" signals only deepens.
10 years ago, gravitational waves changed astronomy. A new discovery shows there’s more to come
Carl Knox, OzGrav, Swinburne University of Technology Simon Stevenson, Swinburne University of Technology Ten years ago, scientists heard…
Scientists use supercomputers to ask: What was before the Big Bang?
Scientists are turning to powerful supercomputer simulations to solve Einstein's equations and finally explore what happened before the Big Bang.
The Viewpoint: A new observatory is assembling the most complete time-lapse record of the night sky ever
Now operational, the Vera C. Rubin Observatory is creating a 10-year movie of the universe to investigate everything from the nature of dark matter to the threat of nearby asteroids.
Head-on ‘Eye of Sauron’ blazar jet solves cosmic neutrino mystery
A rare, head-on view of the blazar PKS 1424+240 reveals how relativistic effects make it a top source of cosmic neutrinos and gamma rays, solving a decade-long mystery.
JWST confirms most distant black hole from early universe
Using the James Webb Space Telescope, astronomers have confirmed the most distant black hole ever found, a behemoth that challenges our understanding of how cosmic giants form so early in the universe's history.
UC Santa Cruz physicist offers 2 new dark matter theories
A UC Santa Cruz physicist proposes two novel theories suggesting dark matter emerged naturally from the extreme gravitational conditions of the early universe.
