Jupiter-like planet 8 UMi b, named Halla, orbits its host red giant star Baekdu closely. The red giant's merger with a white ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

Earth’s history has been punctuated by at least five major ice ages. Some of these frigid periods of prolonged global cooling saw much of our planet locked in ice and snow for 100 million years. It ...

UCLA astrophysicists have now measured the shape of the orbits of exoplanets—from the size of Jupiter down to the size of Mars—and shown that small planets have nearly circular orbits, while giant ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

The classical picture of star and planet formation suggests that a star’s rotational axis and the orbital planes of its planets should be aligned. However, exoplanetary systems have considerable ...
