The Hubble Space Telescope is 30 years old, and in its long career it’s photographed many of the 150 “globular clusters” that surround the Milky Way galaxy—like its latest photo, this week, of NGC ...
This article was originally published on The Conversation. Read the original article. One of the most fundamental questions in modern astrophysics is how galaxies first formed. The Milky Way, the ...
August evenings in the Northern Hemisphere are prime for seeking out globular star clusters. Among the brightest and best for northerners is the Hercules Cluster (M13), which British astronomer Thomas ...
A strange, newly measured clump of stars orbiting the nearby Andromeda galaxy has the lowest level of heavy chemical elements ever seen in one of these mysterious star clusters. Named RBC EXT8, this ...
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 ...
Globular clusters are among the most enigmatic objects in the Universe. They are systems of about 100,000 stars packed into regions of the order of just 10 parsecs (a few tens of light years) in ...
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 ...
“Star cluster” is a generic way for astronomers to refer to a group of stars that formed from the same material and are gravitationally bound for at least some period of time. There are two major ...
