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.
Bigger galaxies tend to dominate the smaller, when the two collide. But the pending battle between our Milky Way and the Andromeda galaxy might be a much fairer fight than we previously thought.
When and where you see the Moon in the daytime depends on what phase it is in.
There are plenty of astronomical things to watch out for this year beyond this week's lunar eclipse, including new Moon landings and a space station falling back to Earth.
Studying lunar eclipse could help us work out what's happening on exoplanets.
There is plenty of excitement about the lunar eclipse this week, but don't believe all you read and hear about this wonderful astronomical event.
From blindingly bright and burning hot to pleasantly 'candle-lit', the first years of the universe would have been spectacular to see.
A bunch of uncommon things all happening at the same time mean this full moon will have some special attributes.
The galaxies, stars and planets in our universe can look very different when you view them through equipment that sees beyond the visible light our eyes can see.
Four star names from Aboriginal Australia have been recognised by the International Astronomical Union. So what are they and where to find them?
Your guide to some of the best meteor showers for 2018. Where to look and when in both the northern and southern skies to catch nature's fireworks.
Scientists looking for signs of alien life from the mystery object passing through our Solar system say they've found nothing "so far".
We’ve only travelled into space in the last century, but humanity’s desire to reach the moon is far from recent.
In mid 1967, PhD student Jocelyn Bell at Cambridge University was helping to build a telescope. She went on to discover a little bit of "scruff" - the first evidence of a pulsar.
A guide to meteor showers – what to look out for and when.
A solitary planet in an eccentric orbit around an ancient star may help astronomers understand exactly how such planetary systems are formed.
A new look at some of the oral traditions of Aboriginal Australians shows a deep understanding of three red-giant variable stars, long before European observers.
Astronomers have detected what is believed to be the first interstellar object ever seen passing through our solar system.
The science of red skies can also help us understand how stars form.
Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.
