Greetings stargazers. Occasionally, the calendar aligns so that I get to complain about daylight saving time in this column on the same weekend it goes into effect. I need to take the chance to do ...

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 ...

Cepheid variable stars are a vital rung on the “ladder” astronomers use to determine the distance to astronomical objects. These pulsating stars, which change in brightness as they also change in ...

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 ...

The newest delta Scuti (SKOO-tee) star in our night sky is so rare it's only one of seven identified by astronomers in the Milky Way. The star -- like our sun -- is in the throes of stellar evolution, ...

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. Open clusters act as ...

Sparkling with an exceptional blue-toned brilliance and exhibiting wild variations in both brightness and spectrum, the luminous blue variable (LBV) is a relatively rare and still somewhat mysterious ...

Spring is galaxy season. If you have a small telescope, this is a good time of year to get it out to find galaxies in the sky. Because most will appear as dim fuzzy blobs, a detailed star chart is ...

We present the first analysis of results from the SuperWASP Variable Stars Zooniverse project, which is aiming to classify 1.6 million phase-folded light curves of candidate stellar variables observed ...

Yardsticks are very useful around the house when you need a measurement. (I have also used them to fish out toys the cat knocked under a low piece of furniture.) They are standards by which we can ...

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 ...
