The formation of the Milky Way is one event that we’re no able to physically observe (obviously). We’re inside the galaxy at its current point in history, and so we can see how it currently looks. We ...

EVANSTON, Ill. --- The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A string of detections -- ...

A study published today in Astronomy & Astrophysics marks a significant milestone in our understanding of the formation and dynamical evolution of multiple stellar populations in globular clusters ...

An international team led by ICREA researcher Mark Gieles, from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), has ...

Globular clusters are the most massive and oldest star clusters in the Universe. They can contain up to 1 million of them. The chemical composition of these stars, born at the same time, shows ...

Globular clusters, among the oldest bound stellar systems in the Universe, offer a unique laboratory for understanding stellar evolution and dynamics. Traditionally considered simple stellar ...

As we carefully map the stars of our Milky Way, we're able to identify features that tell us of its history. These include local details, such as the stars that have passed through an area from which ...

A team of astrophysicists has unveiled how colossal stars thousands of times more massive than the Sun shaped the earliest star clusters and galaxies. These short-lived giants not only forged the ...

Our Milky Way Galaxy is surrounded by about 200 compact groups of stars, containing up to a million stars each. At 13 billion years of age, these globular clusters are almost as old as the universe ...
