A LIGO team member describes how the detection of a gravitational wave from a new source – merging neutron stars – vaults astronomy into a new era of 'multi-messenger' observations.
This enhanced-color image of Jupiter’s south pole and its swirling atmosphere was created by citizen scientist Roman Tkachenko using data from the JunoCam imager on NASA’s Juno spacecraft.
We may need to re-think our models of Jupiter’s formation thanks to the first results from Juno probe orbiting the planet, and new observations from Earth.
ESO provides new ways to access the southern sky for Australian astronomy.

Australia's new partnership with the European Southern Observatory will give our astronomers access to much bigger telescopes.

It's almost impossible for any human to spot something unknown or unusual in the massive amount of data collected by our telescopes. So we're teaching an intelligent machine to search the data for us.
Light from the universe’s first galaxies destroyed the hydrogen atoms that formed during the Big Bang.

A new telescope aims to figure out what became of the universe's original atoms once the first stars began to shine.
SKA South Africa
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.
Jupiter and its moon Io really do look like they do in this latest image by NASA’s Juno probe.
Many images of planets have been manipulated. So have we seen their true colours? Not always, it turns out. But Jupiter's red spot really is red.
Artist’s concept of the supermassive black hole and the gas clouds surrounding it.

Astronomers have detected clumpy gas clouds on the verge of being swallowed by a supermassive black hole, rushing towards it at over 537,000 miles an hour.
Windy black hole.
It was a rare and brief event, but powerful telescopes helped scientists get a glimpse of a black hole letting out a wind at 3,000km per second.
All is not calm in the cosmos.

Stargazing seems such a quiet, calm activity. But whether our eyes can see or not, those stars out there are in constant flux. Time-domain astronomy studies how cosmic objects change with time.

The universe looks very different with X-ray vision, revealing some of the most energetic interactions in our galaxy. Japan's new Hitomi telescope will help us see these wonders.

Dark energy is a completely unknown source making up 70% of the universe. Will any of the new projects designed to find out what it is succeed?

The laws of physics dictate that to pick out ever fainter objects from space and see them more sharply, we're going to need a bigger telescope. And that means we need massive mirrors.

Jupiter had a big influence on how our solar system's planets formed. New research – led by a high school student – tried to nail down how rare Jupiter analogs really are in other planetary systems.
A telescope can open up on the wonders of the heavens.

Stargazing in your back yard or on a camping trip can amaze and inspire. If you're thinking of buying a telescope, here are a few key things you should look out for.
Images of galaxies far away may be forever blurred – no matter how big the telescope.
Telescopes are getting larger and larger as astronomers are hoping to get a good view of the most distant objects in space. But, it turns out, bigger isn't always better.
Wide-eyes: the Square Kilometre Array in the Karoo in South Africa.
The Square Kilometre Array is the world's largest telescope – what will it do and how does it work?

Astronomers aren't mere stargazers these days. One researcher explains the ins and outs of how they collect data from far-off galaxies and what they do with it back at the office.
Hubble in orbit.
The Hubble Space Telescope launched 25 years ago in 1990. But O'Dell started on the project in 1972, garnering support for the world's first telescope free of Earth's atmosphere's blurring effects.

As an astronomer, I get a lot of requests for help. “I’d like to buy a telescope,” the conversation usually goes. “Can you give me some tips on what to look for?” Sadly, there’s little advice I can offer…
