Alien planets are far away but extreme lasers on Earth are giving scientists a way to investigate what they're like.

A new study shows that stars with low magnetic activity are likely to support exoplanetary systems, making the hunt for these celestial objects less random.

By applying machine learning to vast TESS datasets, researchers have built one of the most precise catalogs of nearby exoplanets to date.

Talk about a hot mess. Scientists have uncovered a hellish “lava world” where temperatures soar to a blistering 2,700 degrees ...
