NASA’s TESS spots its first exoplanets and supernovae

From its first data set, astronomers have already discovered new and exciting exoplanets and pivotal distance-measuring supernovae

Black holes are ruled out in explaining dark matter

Astronomers are still hunting down the mysterious dark matter that makes up most of the matter in the Universe

NASA’s Kepler Space Telescope has uncovered an unusual category of supernova explosion

A supernova is challenging astronomers’ models of how exploding stars distribute their elements

They release a billion times more energy, rivalling supernovae in their explosive power

Galaxies “waste” large amounts of material generated by star formation, according to new research

Evidence of a series of massive supernova explosions near our Solar System, which showered our planet with radioactive debris, has been found

Rapidly spinning neutron stars called magnetars could explain two extremely unusual stellar explosions

We’re made of star stuff, so how many Earth-like planets can one stellar explosion make?

Meet the stars that teach us something interesting about our own Sun
