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. Subscribe to our ...

Astronomers using the Swiss 1.2-metre Euler telescope at ESO’s La Silla Observatory in Chile have found a new type of variable star. The discovery was based on the detection of very tiny changes in ...

The brightness of variable stars, exemplified by Algol (Beta Persei), can be estimated by comparing their visual magnitude to nearby stars of known magnitudes. Algol, an eclipsing binary star system, ...

The article details various types of deep-sky objects observable by amateur astronomers, including double stars, variable stars, open and globular star clusters, emission, planetary, and reflection ...

What can star variability—changes in a star's brightness over time—teach astronomers about exoplanet habitability? This is what a recent study accepted for publication in The Astronomical Journal ...

AUSTIN, Texas — University of Texas at Austin astronomers Michael H. Montgomery and Kurtis A. Williams, along with graduate student Steven DeGennaro, have predicted and confirmed the existence of a ...

Variable stars play a key role in understanding the Milky Way and the universe. The era of astronomical big data presents new challenges for quick identification of interesting and important variable ...

A new ancient star type and a bunch of erupting protostars were discovered by astronomers monitoring around a billion Milky Way stars over 10 years. When you purchase through links on our site, we may ...
