Astronomers just weighed a 'little red dot' discovered by the James Webb telescope " and found a massive, 'naked black hole' inside
2+ hour, 7+ min ago (802+ words) Astronomers weighed a black hole in a "little red dot" discovered by the James Webb telescope. They found it to be so overmassive that it may have formed before its host galaxy had a chance to develop. Astronomers have found…...

Gigantic, ancient black hole threatens to upend cosmic history
4+ hour, 50+ min ago (652+ words) Debate still swirls around the nature of "little red dots," black holes glimpsed in the early universe by the James Webb Space Telescope. A controversial new weigh-in may settle the matter By Joseph Howlett edited by Lee Billings An artist's…...

4+ hour, 54+ min ago (624+ words) starlust. org NASA's balloon-borne instrument scoured the Antarctic's icy air for high-energy neutrinos Last year in December, a NASA-designed machine called the Payload for Ultrahigh Energy Observations (PUEO) flew at 120, 000 feet above the vast Antarctic ice sheet. Suspended beneath a…...
UT Scientists Help Measure Universe's Expansion with Gravitational Waves
16+ hour, 8+ min ago (177+ words) An era of precision gravitational astronomy has arrived, and UT physicists are helping lead the way. The LIGO'Virgo'KAGRA Collaboration detected these 161 gravitational wave events between April 2024 and the end of January 2025. Each yellow curve represents the rapid shift in frequency…...
Scientists Unveil Multiple Black Hole Formation Methods
18+ hour, 53+ min ago (515+ words) A 'stellar-graveyard' plot showing the masses of all the black holes and neutron stars detected by LIGO-Virgo-KAGRA in the latest catalogue. The LIGO-Virgo-KAGRA (LVK) Collaboration has today released its latest catalogue of gravitational-wave detections. The data analysed for this update…...
A strange gravitational wave looked wrong, and it could be a first hint of dark matter
18+ hour ago (912+ words) For a decade, physicists have caught the ripples from black holes crashing together. Each time, they assumed the same setup: two black holes spiraling in through empty space. The math fit, so nobody tested the assumption closely. One team finally…...

Scientists find the Universe has multiple ways of manufacturing black holes
20+ hour, 6+ min ago (389+ words) Researchers from the LVK collaboration and Monash University say analysis of the latest release, the Gravitational-Wave Transient Catalog (GWTC-5. 0), points to evidence that binary black holes form through multiple distinct pathways rather than a single dominant process. The catalogue draws…...
