Mysterious ‘little red dots’ seen by the James Webb Space Telescope can be explained by a new kind of black hole enshrouded ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

A new study on some 1,600 galaxies based on data from the Chandra X-ray Observatory reveals that many small galaxies do not ...

In May 2019, astronomers picked up something strange in the fabric of spacetime. The LIGO and Virgo detectors recorded a gravitational wave that lasted just one-tenth of a second. The signal, known as ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when all of space, time, and energy were born from a single infinitely dense ...

The James Webb Space Telescope has uncovered traces of colossal, short‑lived stars that blazed out in the universe’s first ...

Over the past decade, the LIGO-Virgo-KAGRA (LVK) network has detected hundreds of black hole mergers, but none quiet as large as GW231123. At 225 solar masses, the black hole resulting from the merger ...

While nearly all massive galaxies possess central black holes, the presence of such black holes in dwarf galaxies remains an open question, with previous estimates identifying them in only 0.5% of ...

To study the origins of our universe is to struggle with profound chicken-or-egg questions. We know the Big Bang happened. Cosmologists can see its afterglow in the sky. But no one knows whether the ...

Black holes, born from dying stars, are cosmic giants that grow by consuming matter and merging with others. While invisible themselves, their feeding frenzy creates brilliant light. Despite their ...

Astronomers say they've discovered a new record holder for the most massive black hole merger to date. The merger is so big — roughly 255 solar masses — that it shouldn't technically be possible ...
