Our galaxy should be full of traces of dead stars. Until now, we have found surprisingly few of these supernova remnants, but a new telescope collaboration is changing that.
Many galaxies are too faint or small for us to observe easily – but science can help us work it out.
Sagittarius A* lies in the southern sky, passing directly above South Africa.
The pulsar PSR J0523-7125 is more than ten times brighter than any other radio pulsar outside the Milky Way.
Studying the extreme environment of the Virgo Cluster — which comprises thousands of galaxies — helps us learn what factors can affect and start or stop star formation.
After six decades during which it tracked lunar missions, spotted distant pulsars and quasars, and even expanded our concept of the size of the Universe, the Parkes telescope is still going strong.
The sky on other planets doesn’t look the same as the sky on Earth does. And that’s because of the different gases in Earth’s atmosphere.
Fluctuating radio waves that appear to come from near the heart of the Milky Way are a new puzzle for astronomers.
Scientists have a good estimate on the staggering number of stars in the universe.
The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.
Technology is allowing astronomers to study and analyse galaxies in far more detail than was previously possible.
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?
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.
Based on what we currently know about the density of giant radio galaxies in the sky, the probability of finding two of them in this region is extremely small.
Not all planets orbit stars. Rogues float through the galaxy in darkness and are almost impossible to see.
A new method suggests we should aim to detect dark matter haloes by tracing galactic gas.
