Just like volcanologists monitor volcano activity to predict eruptions, astronomers can monitor stars to predict explosions.

If dark energy isn’t constant, we may need to rewrite the standard model of cosmology.
One hundred years ago, one star changed our view of the universe, proving that the Andromeda “nebula” was a galaxy like our Milky Way.
Analysis of two major cosmic blasts deepens the mystery of where the universe’s ‘heavy’ elements come from.
Where specialized algorithms fail to classify star-borne pulses, human volunteers with just a little training can step in.
Analysis of fragments of the first solids that emerged out of the birth of the sun date our supernova as being 4.6 billion years old.
There are signs that Betelgeuse may be evolving rapidly – meaning a supernova explosion may happen sooner rather than later.
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.
Different measures of the rate of the Universe’s expansion give different results – and a new measurement technique only makes matters more complicated.
Astronomers have found that mysterious dark energy may originate in black holes.
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.
Gamma-ray bursts occur when a massive star explodes or when two neutron stars merge. A newly discovered burst has puzzled astronomers, as it lasted much longer than astronomers would have expected.
Radio telescopes produce enormous amounts of data, and we need immense computing power to produce even a single image like this one.
It’s long been a mystery how black holes form, now astronomers are on the verge of cracking it.
The discovery of an ancient star in the Milky Way’s halo is providing evidence for another source that would have produced the galaxy’s heavy elements.
Gravitational waves reveal the demise of super-dense neutron stars spiralling into their black hole companions - the first time such strange and exotic star systems have ever been observed.
Traces of radioactive iron from the ocean floor, Antartica and the Moon reveal several waves of dust from distant stars over the past 10 million years.
New discovery settles a wager between astrophysicists: black holes can merge repeatedly.
Albert Einstein may have been the ultimate example of a visionary genius, but that did not stop him from twice losing his way due to beliefs that were perhaps not so scientific.
When scientists created the Higgs particle with protons, they needed the 10km-wide Large Hadron Collider. A muon machine could achieve it with a diameter of just 200 metres.
