Astronomers study stars by looking at the different colors of light they emit—colors they capture and analyze using ...

Astronomers developed a technique that uses a star's spectrum to chart variations in its temperature to the nearest tenth of ...

Like a boiling soup on a stovetop, the star's scorching material erupts on its surface in bubbles, which astronomers estimate swell to a whopping 75 times our sun's size. "It is spectacular that ...

Astronomers have captured a sequence of images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained ...

Astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained in July and ...

Aside from the Sun, only a few nearby, bloated stars appear large enough to capture any features on their surface, however crude. New images released Sept. 11, however, capture one of the most ...

Astronomers were able to capture detailed observations of massive gas bubbles moving on the surface of a star, named R.

For the M-dwarfs and brown dwarfs, the team aspires to obtain long-sought data regarding their sizes and temperatures ... from the Earth's surface. For example, the stars that are the smallest ...

Astronomers have observed the detailed motions of giant gas bubbles on the surface ... causing the star’s core to collapse. This pressure on the core also increases the star’s temperature ...

Astronomers have observed the detailed motions of giant gas bubbles on the surface of a nearby star for the first time, which rise and fall like the inside of a lava lamp. The massive hot gas bubbles ...
