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 ...

A vast, but previously unknown structure has been discovered around our own Milky Way galaxy by an international team of astronomers. The announcement is being made on behalf of Drs. Annette Ferguson, ...

Using ESA's XMM-Newton satellite, astronomers have conducted deep observations of a massive galaxy known as NGC 5746. As a ...

Scientists have identified a never-before-seen supernova, SN2021yfj, which exploded after losing nearly all of its outer layers. Instead of light elements, it revealed silicon and sulfur from deep ...

A primordial stellar stream discovered in the outer reaches of the Milky Way has a lower proportion of heavy elements than any known stellar system in our galaxy. Observations with the Gemini ...

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 ...

Stellar groupings orbiting in the outskirts of the Milky Way shed new light on the evolution of our galaxy as well as the elusive dark matter that surrounds it. Scientists from the Carnegie ...

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 ...
