Interstellar comet 3I/ATLAS wasn’t supposed to be there — meet the astronomer who discovered it
On the night everything changed For most observers, July 1, 2025 began like countless other evenings at the University of Hawaii’s Institute for Astronomy. Data streams arrived in quiet rhythm, signaling another routine sweep of the sky. But for senior software engineer and astronomer Larry Denneau, the moment carried an unfamiliar weight. A routine routine,…

Study Claims First Direct Evidence of Dark Matter Shaping the Cosmos
New claims spark renewed interest in one of science’s biggest mysteries Researchers are reporting what they describe as the first direct evidence for dark matter, the elusive substance thought to bind galaxies and weave a vast cosmic web. The claim, still under scrutiny by the scientific community, could mark a turning point in our understanding…

Could NASA’s Fermi Telescope Have Seen Dark Matter for the First Time
Overview: A Possible First Glimpse of Dark Matter In a development that could rewrite our understanding of the universe, scientists are evaluating whether NASA’s Fermi gamma-ray space telescope has finally detected dark matter. For decades, dark matter has eluded direct observation, leaving astronomers to infer its existence through gravitational effects on galaxies and cosmic structures.…

New Study Claims Direct Evidence for Dark Matter, Stirring Global Debate
A Landmark Claim in the Dark Matter Debate For nearly a century, scientists have wrestled with the mystery of dark matter — a nonluminous substance believed to make up most of the matter in the universe. The idea emerged from observations of galaxy rotation, gravitational lensing, and the cosmic web that links galaxies over vast…

Dark Matter Seen? NASA Fermi Signals First Direct Detection
What would a dark matter detection mean? For decades, scientists have looked for direct evidence of dark matter, the invisible substance that makes up about 85% of the matter in the universe. While its existence is inferred through gravitational effects on galaxies and cosmic structures, a confirmed direct detection would transform astrophysics and particle physics.…

Study Claims to Provide First Direct Evidence of Dark Matter: What It Means
New Claims of Direct Evidence for Dark Matter A recent study has sparked renewed debate in astronomy by claiming to provide what researchers describe as the first direct evidence of dark matter. For nearly a century, scientists have inferred the existence of dark matter from gravitational effects on galaxies, clusters, and the large-scale structure of…
