Their discovery would not have been possible without a special cosmic yardstick—exploding stars, or supernovae—specifically the variety known as Type Ia. Because Type Ia supernovae are visible ...

Explore the dynamic life of the spiral galaxy NGC 337 as captured by the Hubble Space Telescope, featuring a mix of old and ...

This is particularly true for one particular kind of supernova known as Type Ia. An overview of the different proposed Type Ia supernova progenitors has been published on the arXiv preprint server.

In common types of supernova, a blast at the centre of the star ejects material at high speed into surrounding space. The expansion of this material releases energy, causing the object to shine ...

This is a supernova explosion. Astronomers aim to understand what types of stars produce different kinds of explosions. Do more massive stars result in brighter explosions? What happens if a star ...
