Are there stars other than the Sun that might explode soon close to us? Yes, there are! As long as by ‘soon’ we mean within a million years.
There are lots of places where it’s much, much hotter than the Sun. And the amazing thing is that this heat also makes new atoms - tiny particles that have made their way long ago from stars to us.
A massive star, with a radius 500 times that of our sun, exploded. But the supernova fizzled – it was weak and dim. Figuring out what went wrong led to insights about how rare binary star systems form.
The ‘oldest known nova’ (a star explosion) in the sky was actually not a nova, astronomers show.
Our brain cells do look a lot like a map of the universe – but that doesn’t mean they’re the same thing.
The Swift Observatory passed a milestone: 1 million snapshots of the universe. These exquisite and revealing pictures have captured the births and deaths of stars, gravitational waves and comets.
A team of astronomers captured the moment when a wayward star was pulled into the mouth of a supermassive black hole.
If we survive for another 7.59 billion years, our planet will spiral into the outer layers of the dying sun and melt away forever.
From supernovae explosions to the expansion of the universe and why the sky is blue: you can learn a lot about the universe in the kitchen.
Stargazing seems such a quiet, calm activity. But whether our eyes can see or not, those stars out there are in constant flux. Time-domain astronomy studies how cosmic objects change with time.
Extragalactic astrophysicists want to know how and why galaxies stop forming stars, change their shape and fade away. With help from citizen scientists, they’re figuring it out.

Tanya Hill speaks with Meg Urry about distant galaxies and the supermassive black holes that lurk in their centres.
A new light in the southern night sky is thought to be an exploding star. It comes as astronomers reveal an ancient nova explosion is now thought to have been two stars colliding.
Two white dwarfs found orbiting each other at the centre of a planetary nebula are now known to have enough mass that they will eventually trigger a special kind of supernova, according to research published…
Our understanding of heavy element production in supernovae, exploding stars way beyond our solar system, may need to change following some discoveries we have made looking not to the skies, but deep under…
Research of a supernova in our galaxy will increase the precision of which we can measure distances outside of our own galaxy…
