Black holes that have been obscured by clouds of dust still emit infrared light, enabling astronomers to spot them for the ...

How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 ...

Sgr A*, at the heart of the Milky Way and clocking in at 4.3 million solar masses, is the closest supermassive black hole we have access to. It's also on the quiescent end of the activity scale, which ...

A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could ...

Astronomers theorize that a low-mass white dwarf, a compact core of a dead star about as large as Earth, could be the culprit. A cosmic mystery surrounding a black hole some 270 million light ...

2024 — Astronomers have discovered a supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang that is consuming matter at a phenomenal rate -- over 40 times the ...

The energy beam from this black hole has travelled to us, just over 100 million years after the Big Bang took place -- setting a new record for the distance from which we've observed such a ...

A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). Most galaxies have a large black hole at their core. The mass of the black hole in the new observations, ...

Most galaxies have a large black hole at their core. The mass of the black hole in the new observations, called 1ES 1927+654, is about a million times greater than the mass of our sun. The ...

The early universe experienced a phase of rapid expansion, known as inflation. For decades, cosmologists assumed that this ...
