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.

There's now strong evidence that Europa might be a worthwhile place to search for life.
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.
Except for a few blue foreground stars, the stars are part of the Milky Way’s nuclear star cluster, the most massive and densest star cluster in our galaxy.

Each fortnight I get the amazing opportunity to speak about my top stories in space on ABC Breakfast News TV but for those of you who hate early mornings I wanted to make sure you got to hear of these…
2015 saw us complete our exploration of all nine planets (including dwarf planet Pluto) in our solar system.
2015 was a year where we expanded our view of the universe, embraced new technologies and got a hint of the profound changes to come.
The light shining through an exoplanet’s atmosphere can give us a hint of whether the planet supports life.

A hint of oxygen and a whiff of methane in a distant exoplanet's atmosphere may be the first evidence we discover of alien life.

A giant golden mirror is on the brink of opening up a glimpse of the very first galaxies to be formed.
It’s crowded up there - the many objects tracked in low Earth orbit.
Near-Earth orbits are filled with useful satellites, and also flying junk. If we're not careful they may collide - literally.
Bigger but not better than Hubble. The James Webb’s primary mirror.
It's urgent that we turn our attention to a high definition space telescope that will allow us to directly image exoplanets.
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.
The galaxies NGC 4038 and NGC 4039, locked in a destructive embrace.
After a slow start, Hubble's ultraviolet vision changed the face of astronomy.
Astronomers from around the world identify their favourite images sent back to Earth by the Hubble Space Telescope.
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.
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.
The Hubble Space Telescope hovers at the boundary of Earth and space.
Twenty-five years on and the Hubble Space Telescope is still taking some amazing images. But there have been a few glitches over the years, right from day one.
Dark Matter: as simulated, the scaffold that underpins the universe.
Dark matter's mysteries are being steadily unravelled by new studies of remote galaxies.

2015 is already shaping up to be a big year in astronomy and planetary exploration, with the best yet to come. Here are some highlights to keep your eye on throughout the year. Opportunity January 25 marked…
Jupiter’s Great Red Spot was much bigger when photographed by Voyager back in 1979.
NASA revealed today that the iconic Great Red Spot on Jupiter has shrunk to its smallest size ever – and astronomers have no idea why. The Great Red Spot is a giant anticyclone storm that has been raging…
The Large Magellanic Cloud galaxy completes a rotation every 250 million years, astronomers have found. Using NASA’s Hubble…
