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 ...

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, ...

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 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 ...

NASA’s Hubble Space Telescope has been trained on a single variable star that in 1923 altered the course of modern astronomy. V1 is a special class of pulsating star called a Cepheid variable that can ...

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 ...

A previously unknown kind of variable star is on brilliant display 7,000 light-years from Earth in a new photo taken by a telescope in the Southern Hemisphere. For years scientists have known that the ...

A large-language-model-based system for classifying stellar light curves, integrating specialized components for text, image, and audio data processing. AI tools are transforming how we observe the ...

R. M. SCOTT has an article on the long-pariod variable stars in the Telescope of September-October, which provides a popular description of the type of star of which Mira is a prototype. The spectra ...
