What is a supernova?

A supernova is a star’s colossal explosion at the end of its life, potentially outshining its entire galaxy. Read about the causes and types of supernovae here. Source: https://earthsky.org/astronomy-essentials/definition-what-is-a-supernova…

CTA prototype LST-1 detects very high-energy emission from the Crab Nebula pulsar

Between January and February 2020, the prototype Large-Sized Telescope (LST), the LST-1, observed the Crab Pulsar, the neutron star at the centre of the Crab Nebula. The telescope, which is being commissioned on the CTA-North site on the island of La Palma in the Canary Islands, was conducting engineering runs to verify the telescope performance and adjust operating parameters.

This supernova ‘pizza’ in a lab mimics the cosmic blast’s splendid aftermath

Nestled in the constellation Taurus, a spectacle of swirling cosmic gasses measuring half a dozen lightyears across glows in shades of emerald and auburn. The Crab Nebula was born of a supernova, the explosion of a giant star, and now, a lab machine the size of a double door replicates how the immense blasts paint the astronomical swirls into existence.

The force is strong in neutron stars

Physicists at MIT analyzed data from earlier experiments in particle accelerators, in order to probe the workings of the strong nuclear force that operates inside atoms. Their work sheds light on this force – one of the 4 fundamental forces of nature – and also illuminates the structure of a neutron star’s core.

Image: Foreground asteroid passing the Crab Nebula

When astronomers use the NASA/ESA Hubble Space Telescope to study the deep sky, asteroids from our solar system can leave their marks on the captured pictures of far-away galaxies or nebulae. But rather than be annoyed at the imprinted trails in Hubble images, astronomers realised they could use them to find out more about the asteroids themselves.

The Crab Nebula was an exploding star

The Crab Nebula, about 6,500 light-years from Earth, is the scattered fragments of a supernova, or exploding star, observed by earthly skywatchers in the year 1054. Source: https://earthsky.org/clusters-nebulae-galaxies/crab-nebula-was-an-exploding-star…
