98.5% of the Sun is made up of two light chemical elements, hydrogen and helium, while the remaining 1.5% consists of other heavier elements such as carbon, oxygen, and iron. The abundance of these ...

The study of stellar astrophysics and galactic structure investigates the life cycles of stars and the organisation of galaxies. At its core, the field explores how stellar evolution, from the ...

An international team of researchers including astrophysicists from the international Pristine collaboration published a paper today in Nature announcing their discovery of the remnants of a star ...

Researchers have uncovered evidence for our sun joining a mass migration of similar "twins" leaving the core regions of our galaxy, 4 to 6 billion years ago. The team created and studied an ...

Learn how new high-resolution images of two nova eruptions offer fresh insight into how these stellar explosions release material and generate shock waves. For the first time, astronomers have caught ...

A deep-space photo of the Jellyfish Nebula in Gemini shows a brain-like structure, capturing the supernova remnant IC 443 and surrounding interstellar gas and stars.

Distribution of very dense groups of stars in the Milky Way, called globular clusters, superimposed on a map of the Milky Way compiled from data obtained with the Gaia Space Observatory. Each dot ...
