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.

Australia’s new partnership with the European Southern Observatory will give our astronomers access to much bigger telescopes.
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 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.
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.
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.
A new telescope aims to figure out what became of the universe’s original atoms once the first stars began to shine.
Hundreds of images of thousands of galaxies have given astronomers one of the most detailed galaxy studies ever compiled.
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.
Galaxies are supposed to be the place where new stars are formed. So what causes some to stop this stellar production line?
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?
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.
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.

Tanya Hill speaks with Meg Urry about distant galaxies and the supermassive black holes that lurk in their centres.
A giant golden mirror is on the brink of opening up a glimpse of the very first galaxies to be formed.
The next decade will be an exciting one for Australian astronomy, as we probe the heavens for answers to age old questions.
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.
Our universe’s most exciting days are well behind us, with new research showing the universe is now slowly but surely dying.
