During a solar eclipse, astronomers who study heliophysics are able to study the Sun's corona – its outer atmosphere – in ...

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 ...

Multi-agent system is promising in space applications, because of its high flexibility and robustness. This work considers controlling a large-scale spacecraft swarm to generate a specified spatial ...

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 ...

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.
