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.

Merging supermassive black holes would emit gravitational waves, allowing scientists to detect them.
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.
By sharing a location with the SKA, HIRAX will be able to conduct science in “radio-clear” skies across its wide frequency range.
Astronomy is accessible to anyone with a view of the sky.
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.
Pulsars are rapidly rotating neutron stars and some of them are know to have a "glitch", and astronomers have captured one as it hapened.
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.
New radio technology has managed to detect the first light in the universe.
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.
All it took was a single email alert to send the world's astronomers searching for the source of the latest gravitational wave detected.
Technology is driving a revolution in the way radio astronomers study the universe, and it could lead to new discoveries.
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.
Astronomers in Puerto Rico have picked up signal from a faint star that's not like anything they've seen before.
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.
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.
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.
