Record-breaking supernova in the CANDELS Ultra Deep Survey (compass and scale)

This is a NASA/ESA Hubble Space Telescope view looking long ago and far away at a supernova that exploded over 10 billion years ago — the most distant Type Ia supernova ever detected. The supernova’s light is just arriving at Earth, having travelled more than 10 billion light-years (redshift 1.914) across space.

This image reveals the sky around the supernova, known as SN UDS10Wil, which is shown inset within its host galaxy.
