Astronomers have spotted the most distant supernova ever seen
Nicknamed "Mingus", it was described at the 221st American Astronomical Society meeting in the US.
These lightshows of dying stars have been seen since ancient times, but modern astronomers use details of their light to probe the Universe's secrets.
Ten billion light-years distant, Mingus will help shed light on so-called dark energy, the force that appears to be speeding up cosmic expansion.
Formally called SN SCP-0401, the supernova was something of a chance find in a survey carried out in part by the Supernova Cosmology Project (SCP) using the Hubble space telescope, first undertaken in 2004.
