The Milky Way above a single MeerKAT antenna in the Northern Cape Province of South Africa. Inset: EHT image of the Milky Way black hole.
Sagittarius A* lies in the southern sky, passing directly above South Africa.
This image shows Sagittarius A*, the black hole at the center of the Milky Way galaxy.
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.
Revealed: Sagittarius A*.
We finally know that Sagittarius A* really exists.
The Hubble Space Telescope was born from a previous decadal survey. What leaps forward will come from this one?
The astronomy and astrophysics decadal survey for the 2020s lays out plans to search for life on distant planets, understand the formation of galaxies and solve deep mysteries of physics.
Concept of a black hole acting as a lens on background light.
Some black holes are isolated in space and therefore near impossible to detect.
You can imagine a white hole as being a black hole in reverse — but is such a thing really possible?
Image of a Wolf Rayet star – potentially before collapsing into a black hole.
It’s long been a mystery how black holes form, now astronomers are on the verge of cracking it.
Some stars travel at high speeds through the universe and sometimes leave spectacular clouds of dust and gas in their wake.

Hypervelocity stars were discovered only 15 years ago and are the closest things in existence to real shooting stars. They travel at millions of miles per hour, so fast that they can escape from galaxies.

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.
New technologies have enabled us to learn more about black holes.
Advanced technologies and the information they collect have revealed how black holes form and behave.

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.

Gravitational waves reveal the demise of super-dense neutron stars spiralling into their black hole companions - the first time such strange and exotic star systems have ever been observed.

New research can help explain how black holes can produce powerful jets.

The black hole is part of a binary star system within our Milky Way galaxy. It orbits a colossal supergiant companion star.

A small add-on to existing gravitational wave detectors could reveal what happens to matter as it becomes a black hole, a process like the big bang in reverse.

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.
Could we travel to other universes using wormholes?
Calculations show that wormholes should create a spectacular display of gamma rays that we could try to observe.

Not all planets orbit stars. Rogues float through the galaxy in darkness and are almost impossible to see.
Falling into a black hole is easily the worst way to die.

The scariest beast in the universe has an insatiable appetite and shreds its victims.
Roger Penrose helped resurrect Einstein’s general theory of relativity, and Reinhard Genzel and Andrea Ghez showed there was a black hole in the middle of our galaxy.
