The supernova 1987A lies around 168,000 light years from Earth, and is the closest stellar explosion we have seen in hundreds of years. Now, the James Webb Space Telescope is revealing new details
The blueish area at the centre of the image represents dense clumps of gas and dust expelled by the cosmic explosion.Voyage across the galaxy and beyond with our space newsletter every month.
It is surrounded by a crescent-like structure in red, a previously unseen feature of supernovae remnants. The crescent is probably an outer layer of gas ejecting from the supernova and it is likely to be madeA dazzling ring of matter encircles the blue area and the crescent, arising from material ousted by the original star in the roughly 20,000 years leading up to the supernova explosion.
Neutron stars typically form following a supernova explosion, but SN 1987A’s one remains elusive. “There’s a lot of gas in the centre of the system,” says Matsuura. “The dust grains absorb the light from the neutron star, which is probably why we haven’t picked it up yet.” These images are some of the most detailed ever captured of a supernova, says Matsuura, who hopes to continue monitoring SN 1987A with JWST. “It’s a very interesting object that allows us to see how supernovae will evolve in time,” she says.On 7 October, Richard Ellis will share recent progress and challenges in the search for the cosmic dawn
