As winter's brilliant stars slip toward the western horizon and the constellations of spring climb higher, Northern Hemisphere observers discover a quieter but richly rewarding sky. Spring is ...

Using the James Webb Space Telescope (JWST) and its predecessor Hubble, astronomers took a close look at thousands of young star clusters in four galaxies and studied these clusters at different ...

A computational model of the early-to-present-day Universe predicts that some of the first stars formed in structures that challenge conventional classification. Read the paper: The emergence of ...

Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open clusters closely associated both in position and kinematics. They provide ...

the constellation Orion with the Orion Nebula Cluster as the central “star” in the sword of Orion, the Pleiades and the Hyades. All three open clusters are highlighted by large yellow circles. Orion ...

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 ...

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 ...

The most massive black holes in the Universe detected by the ripples they make in space time were not born directly from collapsing stars, according to a new study. These cosmic giants instead build ...
