James Webb: Telescope reveals new detail in famous supernova

31 August 2023

By Jonathan Amos
Science correspondent

It's like a celestial pearl necklace.

This is an image of a supernova - an exploded star - taken by the new super space telescope James Webb (JWST).

SN1987A, as it's known, is one of the most famous and studied objects in the southern hemisphere sky.
