New research can help us understand how supermassive black holes formed – and why many of them appear to be more massive than expected.

If a star gets too close to a black hole, it gets shredded and produces a complex ball of light. These videos are the first time this dramatic event has been simulated in detail.
X-rays emitted around black holes can tell astrophysicists about how fast they’re growing.
2024 marks 25 years since NASA’s Chandra X-ray Observatory started detecting X-rays from energetic astronomical events.
MeerKAT has made remarkable contributions to South African and international science.
The discovery raises big questions about widely accepted models of galaxy formation.
The black hole J0529-4351 is 500 trillion times brighter than the Sun.
Pictures of black holes have a white outline around them when photographed, due to one of black holes’ unique and key features.
Do all big black holes in very massive galaxies emit radio waves? We used the latest radio telescopes to find out.
An astronomer and ‘black hole historian’ explains how the parts of the universe black holes grow in might influence how quickly they become bright, supermassive objects.
By timing radio pulses from an array of galactic pulsars, scientists see hints of gravitational waves from supermassive black hole pairs in a breakthrough that may reveal hidden details of galaxy evolution.
Astronomers have found that mysterious dark energy may originate in black holes.
One of the objects is a ‘fossil’ radio source – a leftover from the death of a supermassive black hole that once shot out huge jets of plasma.
Sagittarius A* is a massive black hole at the center of the Milky Way. Now that astronomers have imaged it, they can begin to learn more about black holes within other galaxies across the universe.
We finally know that Sagittarius A* really exists.
Despite the name, some black holes effectively “shine” as they suck up nearby material with such force that it begins to glow. New research reveals a new method for detecting these active black holes.
We have to look back to the Big Bang to find out.
Astronomers have taken a close-up look at the jets of plasma streaking away from a supermassive black hole - one of the strangest and most energetic features of galaxies.
New research can help explain how black holes can produce powerful jets.
Some of the baby radio galaxies found may not be ‘babies’ at all. Rather, they may be ‘angsty teens’, rapidly growing into adults much faster than researchers had anticipated.
