NASA compares the universe's biggest black holes with "each other and to our solar system," in this Goddard Space Flight ...

There's a universe full of black holes out there, spinning merrily away—some fast, others more slowly. A recent survey of ...

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 ...

Astronomers compile a large sample of an unusual class of objects in an effort to connect the dots to the early universe.

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, ...

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

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 ...
