Cambridge, MA – The existence of black holes is perhaps the most fascinating prediction of Einstein’s Theory of General Relativity. When any mass, such as a star, becomes more compact than a certain ...

In 2023, scientists detected the gravitational waves from a black hole collision that seemed impossible. New research finally explains how this "forbidden" black hole came to be, and what it can teach ...

An extraordinarily brilliant point of light seen in a distant galaxy, and dubbed ASASSN-15lh, was thought to be the brightest supernova ever seen. But new observations from several observatories, ...

Astronomers from the University of Hawaiʻi Institute for Astronomy (IfA) have uncovered the turbulent past of a distant red ...

The James Webb Space Telescope (JWST), launched in 2022, continues to reshape how we view the cosmos. Designed to look deeper into space and further back in time than any previous instrument, it has ...

The colossal black hole lurking at the center of the Milky Way galaxy is spinning almost as fast as its maximum rotation rate. That's just one thing astrophysicists have discovered after developing ...

Researchers conducted innovative simulations of spinning black holes grounded in general relativity, which clarified that the ultraluminous accretion disk (i.e., gaseous spiral surrounding a black ...

The LIGO-Virgo-KAGRA Collaboration detected two unique black hole merger events, GW241011 and GW241110, which featured a rapidly spinning black hole and the first observed black hole spinning backward ...

Black holes exert a tremendous influence on their surroundings, meaning that when they spin, they literally drag the very fabric of space and time around with them. That means nothing can sit still ...

NASA's exoplanet-hunting spacecraft TESS has heard the song a star-quaking red giant sings to its partner black hole.
