The solar system still has only eight confirmed planets that are orbiting the sun. It recently had nine planets, but it all changed after NASA and other space agencies decided to demote Pluto to a ...

What can star variability—changes in a star's brightness over time—teach astronomers about exoplanet habitability? This is ...

Science is always an unfinished project. That’s what makes it so much fun. The process—collecting data, building models to explain how the world works, and then dethroning them with new models—is full ...
