Up until now, exoplanet surveys have mostly focused on nearby, bright stars that are sun-like or are red dwarfs, which are known to frequently host planets. While astronomers have discovered thousands ...

NASA's DART mission didn’t just change the orbit of Dimorphos, the asteroid it hit. It changed the orbit of the larger ...

Did you know that satellites are constantly falling? To understand how satellites stay in orbit, imagine standing on a very tall mountain and throwing a ball straight out in front of you. Gravity ...

It provides a dynamic, time-resolved view of planetary transformation, a missing link between young inflated worlds and the compact sub-Neptunes that populate the galaxy.
