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 ...
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 ...
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 ...
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 ...
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 ...
