Like a cosmic butterfly in the sky, radio galaxy PKS 2014-55 was observed by CSIRO researchers with the Australian SKA Pathfinder telescope.
New research does away with dark matter by putting ‘entropy’, a measure of disorder, at the heart of the universe.
When you look at the squiggly lines on Joy Division’s famous album cover, you’re seeing a record of lightning in outer space.
Astronomers have suspected them for ages –now a team as finally spotted a ‘fountain’ in a galaxy far, far away.
There are probably more than a million planets in the universe for every single grain of sand on Earth. That’s a lot of planets. My guess is that there probably is life elsewhere in the Universe.
Astronomers traced a single star as it passed close to the black hole at the centre of our galaxy, and detected the telltale signature of Einstein’s gravity in action.
A giant detector at the South Pole has observed a neutrino from a black hole in a distant galaxy for the first time.
Exactly 99 years after Einstein’s theory of general relativity was proven right in our own solar system, scientists show that it also holds true for entire galaxies.
Astronomers have indirectly spotted some of the first stars in the universe by making their most distant detection of oxygen in a galaxy that existed just 500m years after the Big Bang.
Astronomers are gathering an exponentially greater amount of data every day – so much that it will take years to uncover all the hidden signals buried in the archives.
As galaxies get older they get rounder, and fall victim to the middle-aged spread that catches many of us humans here on Earth.
Black holes may come in many sizes, but there’s still a gap in the middle. The hunt is on to solve the mystery of where are the intermediate size black holes.
Massive, far distant galaxies contain 100 times more gas than we thought possible.
Star Trek: Discovery explores our corner of the block – just a fraction of the galaxy. Some stars are better candidates for intelligent alien life, and it may not be anything like we imagine.
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.
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.
So where did all the dark matter come from?
Understanding how the billions of stars in our galaxy formed and evolved is the subject of a huge galactic archaeology project.
Astronomers have taken a forensic approach to study the stellar halo of a galaxy to reveal hidden secrets on how such galaxies were formed.
Astronomers are making new discoveries about our galaxy thanks to a more detailed map of the Milky Way.
