Milky Way billions of years ago. This remarkable journey, revealed through the most detailed catalog of similar stars to date, transforms our understanding of the solar system’s origins. Published in ...

Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme ...

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

A team of researchers has obtained conclusive evidence placing the Sun, approximately 4.6 billion years ago, as part of a vast migratory stream of stars that left the central regions of the galaxy.

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 ...

Astrophysicists are closing in on one of the strangest possibilities in stellar evolution, a compact remnant that might sit between neutron stars and black holes. These hypothetical “quark stars” ...

The evolution of stars and their interactions with compact objects, such as black holes and neutron stars, remain pivotal in our understanding of the cosmos. Stellar evolution describes the life ...

New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to Type II supernova explosions.

One of the best places to study stars is inside “open clusters”, which are groups of stars that formed together from the same material and are bound together through gravity. Open clusters act as ...

Stellar astronomy and planetary systems form a cornerstone of astrophysical research, uniting our understanding of the life cycles of stars with the intricate architecture of the systems that form ...

This image from the ALMA telescope shows star system HD101584 and the complex gas clouds surrounding the binary. It is the result of a pair of stars sharing a common outer layer during their last ...
