Some unique ‘stars’ might be fueled by dark matter annihilation.
Will the universe keep existing forever? An astrophysicist explains how scientists aren’t entirely sure, but they can make predictions.
Phones can often take great photos, but why photos of the Moon typically disappointing? The Moon itself and camera design are both part of the answer.
Radio astronomy opened up the universe for scientists. They could map new elements across galaxies and also search for signals from extraterrestrial civilizations.
The alien question, while fun, generates misinformation and distracts from the science.
A piece of a suspected rocket found on fire in Western Australia highlights the growing problem of space junk – and how humanity is dealing with it.
A failed star just taught us something new about the search for alien life.
Every single day, space technology impacts our lives. But a new report reveals gaps between what Australians think and what they know about space.
New radio astronomy results reveal how galaxies exchange gas with the intergalactic medium – the raw material for stars and the key to galactic evolution.
The world’s largest space telescope, comprising thousands of antennae in the southern hemisphere, will generate massive amounts of data — some of which will be processed in Canada.
A decade after the first discovery, scientists have used these waves to find a unique merger, a massive binary system and a crystal-clear gravitational wave signal.
The largest telescope in space has been trained on a rocky exoplanet.
Could tiny stars a fraction the size of our solar system’s Sun have habitable planets orbiting them? A new study says it’s possible.
The bright explosion revealed its internal structure.
Two new studies challenge scientists’ previous theories on how the very first stars in the universe formed.
The Moon will indeed be black, kind of. But that’s not why you should look up this weekend.
An ‘extremely stripped supernova’ confirms the existence of a key feature of physicists’ models of how stars produce the elements that make up the Universe.
If you’re like most people, you’ve never heard of it. Meet the ringed asteroid-comet hybrid prowling the outer reaches of the Solar System.
This solar eclipse was created by 2 satellites flying in formation, allowing astronomers to photograph the Sun’s corona.
