Do all big black holes in very massive galaxies emit radio waves? We used the latest radio telescopes to find out.

New ASKAP images reveal a giant hydrogen ring around the spiral galaxy NGC 4632.
A phenomenon called gravitational lensing can help astronomers observe faint, hard-to-see galaxies.
The universe used to be filled with a hydrogen fog, before early stars and galaxies burned through the haze. Astronomers are studying galaxies that tell them about this period in the early universe.

One of the few examples of a fast radio burst and the slow-moving, star forming gas in its origin galaxy has been linked together – thanks to observations from a CSIRO telescope.
When two massive objects – like black holes or neutron stars – merge, they warp space and time.

Upgrades to the hardware and software of the advanced observatory should allow astrophysicists to detect much fainter gravitational waves than before.
The sky is big and full of information that AI tools can help astronomers unlock.

Artificial intelligence tools are making waves in almost every aspect of life, and astronomy is no different. An astronomer explains the history and future of AI in understanding the universe.

Machine learning is becoming an indispensable tool in astronomy by sorting through enormous datasets from telescopes.
Astronomers have found that mysterious dark energy may originate in black holes.
While we can’t see inside a black hole, we can spot the intensely bright glowing disc that surrounds one. Now, we might better understand why these discs appear to ‘twinkle’.
The James Webb Space Telescope is providing astronomers with images and data that reveal secrets from the earliest era of the universe.
It has been one year since the launch of the James Webb Space Telescope and six months since the first pictures were released. Astronomers are already learning unexpected things about the early universe.
Spiral galaxies like M100, pictured here, may hold answers about the nature of dark matter.

A comparison of star-forming galaxies suggests, surprisingly, that dark matter and visible matter do interact – taking us closer to understanding what keeps the galaxies together.
James Webb has peered into the distant Universe.
James Webb has spotted extremely distant galaxies formed soon after the Big Bang, but are they old or young? Or is this the wrong question to ask?
Long before the James Webb telescope brought us these deep field images, artists have been capturing notions of space.
This cluster of galaxies, called Stephan’s Quintet, is a composite image produced from two cameras aboard the James Webb Space Telescope.
NASA released five new images from the James Webb Space Telescope, revealing incredible details of ancient galaxies, stars and the presence of water in the atmosphere of a distant planet.

Recent results cast doubt on dark matter.
The mirror on the James Webb Space Telescope is fully aligned and producing incredibly sharp images, like this test image of a star.

It has taken eight months to test and calibrate all of the instruments and modes of the James Webb Space Telescope. A scientist on the team explains what it took to get Webb up and running.

Next-generation radio telescopes unravel the mysteries of ghostly circles in the sky.
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.
