An illustration of a young solar system immersed in high-energy cosmic rays from a nearby supernova. Unlike considering only direct injection of supernova ejecta, this process naturally explains key ...

A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary 'guest star,' now labeled supernova (SN) ...

It looks like the same mechanism that breaks up airplane contrails might be at play in forming the clumps of hydrogen gas that ring the remnant of supernova 1987A, researchers report. Physicists often ...

Cambridge, MA – Since Galileo first pointed a telescope at the sky 400 years ago, a myriad of technological advances have allowed astronomers to look at very faint objects, very distant objects, and ...

An artist's concept of a highly magnetized neutron star. According to current theory, axions would be created in the hot interior of the neutron star. UC Berkeley astrophysicists say that the strong ...

The creation of dust in spiral galaxies like the Milky Way has been attributed to exploding stars, but most dust in elliptical galaxies may come from a different type of supernova. While on Earth dust ...
