The Guardians of the Galaxy team are rocking the universe again in the latest volume of the science fiction blockbuster. But how does the science stand up to some number crunching?
New research shows the insects use the brightness of different stars to work out which direction to go.

Astronomers are surprised by what they're finding out about galaxies that formed in the early days of our universe, now that sensitive telescopes allow direct observation, not the inference of old.
Untangling the history of the Milky Way.
Understanding how the billions of stars in our galaxy formed and evolved is the subject of a huge galactic archaeology project.
Mysterious Milky Way.
A new discovery can help determine where all the stars in the universe's galaxies actually come from.
The Milky Way as seen from Earth.
Astronomers are making new discoveries about our galaxy thanks to a more detailed map of the Milky Way.
Australians have gazed in wonder at the Milky Way since long before Captain Cook’s time.

What did Isaac Newton, Captain Cook and Eddie Mabo all have in common? Each, in their own way, looked to the heavens to make sense of the world, and the importance of their place in it.
Gaia’s first sky map.
The Gaia catalogue’s incredible precision is only possible due to accurate tracking of Gaia itself from the ground.

Something mysterious is pulling our Milky Way through space at a much faster rate than expected. So what could it be?
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…
Can a galaxy (like NGC 3810 in this case) have a classical spiral structure and also be already dead?

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.
CSIRO’s Compact Array telescope under the Milky Way.
Astronomers think they may have found evidence within our galaxy of some of the missing matter thought to make up our universe.
Elliptical galaxy SDSS J162702.56+432833.9 could be full of life.
A new model suggests that elliptical galaxies are more likely to be habitable than spiral galaxies like our own. Does that mean we're a freak event and elsewhere is teeming with life?

Astronauts living on the ISS get to experience the wonders of the universe's natural phenomena like no one else.
What secrets will space reveal?
Why the Breakthrough Listen project is a step in the right direction in our hunt for life beyond Earth.
Are you afraid of the dark matter?
European Southern Observatory
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.
Observations of the dusty cloud G2 as it approaches and then swings around the supermassive black hole at the centre of the Milky Way.
The best observations yet of a mysterious gas cloud that was heading for the black hole at the hear of our Milky Way reveal it may have more stellar origins.
This artist’s impression of the Milky Way galaxy. The blue halo of material surrounding the galaxy indicates the expected distribution of the mysterious dark matter.
While invisible, dark matter completely dominates our Milky Way, recent measurements of just how much dark matter there is have revealed a bit of a mystery. In a paper published today in the Astrophysical…
The Large Magellanic Cloud (right) visible in the southern sky is a nearby galaxy to our own.

If the solution to a problem does not reveal itself straight away then why not let your initial guesswork evolve? That’s the approach we’ve taken in trying to determine the mass of our galaxy by mapping…
Being spiral in shape, our Galaxy is already in permanent rotational motion. But astronomers have found that the Milky Way…
