Hidden Structure Of Iconic Supernova Seen By JWSTJWST captured this detailed image of SN 1987A (Supernova 1987A). At the center, material ejected from the supernova forms a keyhole shape. Just to its left and right are faint crescents newly discovered by Webb. Beyond them an equatorial ring, formed from material ejected tens of thousands of years before the supernova explosion, contains bright hot spots. Exterior to that is diffuse emission and two faint outer rings. Hidden Structure Of Iconic Supernova Seen By JWSTJWST captured this detailed image of SN 1987A (Supernova 1987A).

Fast And Bright Stellar Explosion Could Be A New Cosmic CollisionArtist's impression depicting a compact object – either a black hole or a neutron star – feeding on gas from a companion star in a binary system. Since gas cannot fall in from all directions in a rotating system, it forms a swirling disc around the compact object.

Remains Of The First-Ever Supernovae In The Universe Finally SpottedThis diagram illustrates how astronomers can analyse the chemical composition of distant clouds of gas using the light of a background object like a quasar as a beacon. When the light of the quasar passes through the gas cloud, the chemical elements in it absorb different colours or wavelengths, leaving dark lines in the spectrum of the quasar. Each element leaves a different set of lines, so by studying the spectrum astronomers can work out the chemical composition of the intervening gas cloud.Remains Of The First-Ever Supernovae In The Universe Finally SpottedThis diagram illustrates how astronomers can analyse the chemical composition of distant clouds of gas using the light of a background object like a quasar as a beacon.
