Astronomers think they've identified which galaxy was the source of a blast radio energy, over in a fraction of a second. And it's much closer to us than the others detected, so far.

Astronomers found something not predicted by current theory when they took a closer look at the emissions from a neutron star with a very strong magnetic field.

Astronomers are getting ready to say good bye to the radio emission from a neutron star merger – one of the most energetic events in the universe – that was detected last year.
The Vela pulsar makes about 11 complete rotations every second, it also has a glitch.

Signals from the first stars to form in the universe have been picked up by a table-sized detector in a west Australian desert. The find also hints at an early interaction with dark matter.

In mid 1967, PhD student Jocelyn Bell at Cambridge University was helping to build a telescope. She went on to discover a little bit of "scruff" - the first evidence of a pulsar.

What caused the Big Bang is still a mystery. And that's just one of the many unanswered questions, in spite of everything we do know about the birth of the Universe.
People used to think that when they looked up at the night sky, they were seeing all of space. Then American astronomer Edwin Hubble found out something so amazing, NASA named a telescope after him.
The Australian Square Kilometre Array Pathfinder uses several telescopes to survey the sky.

After months of running in test-mode, the Australian Square Kilometre Array Pathfinder telescope is now gathering data at an incredible rate to give us a new look at how our universe works.
Very few African universities offer postgraduate degrees in astronomy. This gap in knowledge and training can be addressed through international partnerships and collaboration.

Astronomers are making new discoveries about our galaxy thanks to a more detailed map of the Milky Way.
Jets generated by supermassive black holes at the centers of galaxies can transport huge amounts of energy across great distances.

It's difficult to get jets - powerful, lightning fast particles - to give up their secrets. The new Square Kilometre Array radio telescope could hold the key to solving jets' mysteries.
What's particularly exciting about "first light" images from South Africa's MeerKAT radio telescope is that they prove Africa is a rising star in the world of astronomy.
