Oh hey, I heard ripples in space and time, generated as two black holes merged. Call me back.
Here's a LIGO insider's description of how he got the news of a phenomenon that had first been theorized 100 years ago.
When two black holes collide, the resulting gravitational ripples can be felt across the cosmos.
The detection of gravitational waves is the final confirmation of Einstein's theory of general relativity, and opens up a new window into the cosmos.
Binary black holes come in a variety of forms, but they are all astounding.

It takes something as stupendous as the merger between two black holes to generate detectable gravitational waves. Here's how such incredible cosmic objects form.
The vast expanse of Western Australia is perfect for radio astronomy.
Pete Wheeler, ICRAR
The Murchison Widefield Array sits in remote Western Australia far from noisy civilisation so it can help us understand the universe by tuning into radio waves from the distant cosmos.
Can a galaxy (like NGC 3810 in this case) have a classical spiral structure and also be already dead?
ESA/Hubble and NASA
Extragalactic astrophysicists want to know how and why galaxies stop forming stars, change their shape and fade away. With help from citizen scientists, they're figuring it out.

Four decades later, I find myself surveying 13 billion years of cosmic history and mapping events that really did happen a long time ago in galaxies far, far away.

They're beyond tiny and super mysterious. Neutrinos are an elemental particle that might just help us understand the structure and evolution of the universe.
McDonald and Kajita sharing the happy news shortly after the announcement.
One of tiniest particles in physics has won the biggest prize in science – for the fourth time.

A new study has failed to find evidence of gravitational waves, but that doesn't mean Einstein was wrong about their existence.
Australian astronomers have their eyes on the skies.
The next decade will be an exciting one for Australian astronomy, as we probe the heavens for answers to age old questions.
Every culture derives a different meaning from our common wonder at the mysteries of the universe.

The night sky is part of the shared heritage of all people on Earth. A project to bring Indigenous Australians and astrophysics together reveals our common wonder at the mysteries of the universe.

Cleo Loi was an undergraduate when she made a startling discovery. Her story shows how brilliance, dedication and imagination drive science.
Bye, Earth telescopes! You will never reach my level.
Ground-based telescopes are getting bigger and better while still being cheaper than space telescopes. But the vital scientific contributions made by Hubble demonstrates why we need both.
Wreathed in dust, the death of a supergiant star.
An unremarkable speck in the sky was transformed into an unique astronomical object – and Hubble was there to capture it.
The Hubble Extreme Deep Field, looking back towards the birth of the universe.
Hubble's Deep Field images are the next best thing to a time machine, revealing details of galaxies from the early universe, 13 billion years ago.
Dark Matter: as simulated, the scaffold that underpins the universe.
Dark matter's mysteries are being steadily unravelled by new studies of remote galaxies.

Scientists know so much about dark matter apart from what it is exactly. But are they getting any closer?
Are you afraid of the dark matter?

Every 30 mil years, Earth has to deal with more comet crashes from space and more intense geological activity from within. Dark matter may be the culprit in these episodes that can cause mass extinction.

Telescopes have come a long way since the days when they were all about lone astronomers watching the night sky through their upstairs windows. Today teams of astrophysicists build and use much more modern…
