We still can't see the dark matter thought to make up about a quarter of the universe, but at least now we have a map of its structure.
In the beginning, the Universe expanded very, very fast.
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.
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.
The truth is we don’t really know if space goes on forever – but maybe, one day, we will find out.
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.
Artist’s impression of ZF-COSMOS-20115, a galaxy that stopped making new stars and rapidly turned into a compact red galaxy.
The recipe book for galaxy formation may need to be rewritten after the discovery of a massive galaxy that stopped making new stars early in the Universe's history.
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.
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.
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.
A small section from the ZFOURGE survey, which contains thousands of galaxies spanning billions of years.
Hundreds of images of thousands of galaxies have given astronomers one of the most detailed galaxy studies ever compiled.
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.
Spiral galaxy NGC 3953 is a veritable star making machine, but why do some galaxies stop forming new stars?
Galaxies are supposed to be the place where new stars are formed. So what causes some to stop this stellar production line?
The new discovery: The C-shaped “wide angle tail galaxy” (pink) surrounded by the galaxies of the Matorny-Terentev cluster (white).
The find by citizen scientists of at least 40 galaxies in a cluster more than a billion light years away is the astronomical equivalent of finding a needle in a haystack.

Something mysterious is pulling our Milky Way through space at a much faster rate than expected. So what could it be?
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.
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.
Supermassive black holes, containing as much mass as millions or billions of suns, exist at the centre of all galaxies, including our own Milky Way.
NASA Goddard Space Flight Center
Tanya Hill speaks with Meg Urry about distant galaxies and the supermassive black holes that lurk in their centres.
Gilt-edged. The James Webb telescope steps up the search.
NASA's Marshall Space Flight Center
A giant golden mirror is on the brink of opening up a glimpse of the very first galaxies to be formed.
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.
There are so many galaxies, you can write with them!
It’s National Science Week and this year the annual citizen science project run by ABC Science is astronomy-themed. No guesses for knowing that I’m excited about that! It’s also a nod to 2015 being the…

Dwarf galaxies are the most abundant galaxies in the universe yet little is known about how they behave, and the impact of larger neighbours.
