Scientists have a good estimate on the staggering number of stars in the universe.
Technology is allowing astronomers to study and analyse galaxies in far more detail than was previously possible.
Australia’s ASKAP radio telescope probes the Universe more deeply than ever before, revealing unseen features of the cosmos.
Astronomers have taken a close-up look at the jets of plasma streaking away from a supermassive black hole - one of the strangest and most energetic features of galaxies.
Billions of galaxies are in the universe, with billions of stars in every galaxy. Could billions of planets be out there too?
More than 60 images capturing huge expanses of sky are sent to us from Chile. Within them we can see thousands of bright spots. What do we find when we look closer?
Astronomers know a lot about what’s in outer space – and think it’s possible it never ends.
Fast radio bursts are the focus of a young and fascinating field of astronomy. Researchers just released data on more than 500 new bursts, quadrupling the total number of detected events.
A galaxy 320 million light-years away has a surprisingly similar structure to the Milky Way, suggesting our galaxy isn’t as unique as it once seemed to astronomers.
Thanks to the discovery of five twinkling galaxies in a rare alignment, astronomers have been able to calculate — for the first time — the properties and geometry of an invisible gas cloud in space.
Some of the baby radio galaxies found may not be ‘babies’ at all. Rather, they may be ‘angsty teens’, rapidly growing into adults much faster than researchers had anticipated.
These results might lead us to revise our understanding of how galaxies stop forming their stars.
A new method suggests we should aim to detect dark matter haloes by tracing galactic gas.
COVID-19 may have messed up school and shut down a lot of entertainment venues. But you can still brighten things up by doing a little stargazing at night, an astronomer says.
Dark energy is probably a sea of constant energy in empty space itself, according to new research.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
Like a cosmic butterfly in the sky, radio galaxy PKS 2014-55 was observed by CSIRO researchers with the Australian SKA Pathfinder telescope.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.
New research using the Hubble Space Telescope reveals that galaxies may be forming at faster rates than previously believed.
This observation means astronomers can now develop and test theories that explain how high-mass stars gain their mass.
