The planet Halla looks like it should have been devoured by its host star, a red giant called Baekdu – but a secret in the star’s past may hold the answer to the planet’s present.
Our Sun will likely go out quietly – but not all such stars do. A new radio detection of a supernova can help us better understand these cosmic cataclysms.
The binary star WR140 is surrounded by an astonishing array of nested shells of dust swirling into space.
Surprising findings on an exquisite and huge star system in our Milky Way suggest future potential for an extremely rare gamma-ray burst. This event has never been observed in our galaxy.
Why isn’t there an endless variety of planets in the universe? An astrophysicist explains why planets only come in two flavors.
Radio flare may be the result of a giant star orbiting some unusual object – a combination we have never seen before.
The signal came in on ANZAC Day, ripples in space-time from the merger of two neutron stars an estimated 500-million light years away. But where it happened is still a mystery.
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.
A cosmological event could have unleased the huge comet or asteroid that led to the demise of the dinosaurs.
Magnetars are stars that are incredibly dense, rapidly spinning, amazingly hot and – as their name suggests – are the most magnetic objects known in the universe. The magnetic field on the surface of a…
