This solar eclipse was created by 2 satellites flying in formation, allowing astronomers to photograph the Sun’s corona.

During a solar eclipse, astronomers who study heliophysics are able to study the sun's corona—its outer atmosphere—in ways they are unable to do at any other time.

Astronomers have spotted signs of an unusual, rainbow-like pattern decorating the surface of WASP-76b, a "hot Jupiter" exoplanet some 637 light-years away. The circular "glory" lights, if ...

The eight planets in our solar system (yes, it's still weird for me to write "eight," too) orbit the sun in roughly circular paths, although they're ever-so-slightly ellipses instead of circles. A ...

Planets with a similar size to Earth have been found to follow a similar circular orbit, which could have implications in the search for life. Circular orbits can support a relatively stable climate.
