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.

On the journey to discovery with the ‘gifted mentor’ Takaaki Kajita, one of this year’s Nobel Prize winners, from some one who studied with him.
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.
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.
The next decade will be an exciting one for Australian astronomy, as we probe the heavens for answers to age old questions.
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.
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.
An unremarkable speck in the sky was transformed into an unique astronomical object – and Hubble was there to capture it.
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’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?
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…
Interstellar’s protagonists spend a significant portion of the movie’s 169-minute running time giving mini-lectures – sometimes with props and a little whiteboard – on theoretical physics. The characters…
Poor old Richard Branson. SpaceShipTwo has only just stopped smouldering after struggling to get more than 20km from the Earth and there’s the Nolan brothers getting Matthew McConaughey and Anne Hathaway…
Millions of asteroids of all shapes and sizes are littered throughout the inner solar system. In the past three decades, scientists have spotted as many as 500,000 but many more remain unseen. Many of…
One of the main aims of the Apollo missions of the 1960s was to determine whether the moon had any water on it. If man were to build a colony on the moon, having water present would make living there easier…
Katherine Mack, astrophysicist at the University of Melbourne, answered questions posed by the public on Reddit. The Conversation has curated the highlights. Dark Matter How do you explain dark matter…
