NASA is already pulling together plans for what could become its first long-lived robotic rover on the moon's surface, designed to sniff out water and targeting a landing date of 2022.
The 1995 discovery showed that the sun isn't the only star to host a family of planets — something we had long figured but never demonstrated — and also that the universe is really, really weird.
Some ice deposits on the moon are younger than expected, researchers say, and it appears these deposits came from multiple sources at different times in our solar system's history.
The European-Russian ExoMars 2020 mission will have to find some parachute fixes fast if it wants to be ready for launch next summer.
Right now, it's a solar system known only by the designation HD 17156. Before 2019 ends, it will bear an entirely different second moniker — perhaps one suggested by you.
A mysterious bird and its seemingly huge talons photobomb an all-sky camera's view of the cosmos in this lucky shot from the La Silla Observatory in Chile.
Was Venus once covered in a liquid water ocean? A new study suggests it was not, which could diminish hope that eons ago, warm and wet conditions allowed life to arise on the planet.
Observations of the interstellar Comet Borisov have been flooding in for six weeks, and the more astronomers duplicate one another's work, the more confident they are in their analysis of the object.
A new video from NASA shows how a supernova explosion morphs and changes during a 13-year period, including unusually fast-moving shock waves.
A new meteorite addition to the Field Museum's collection resembles a malodorous mud brick, but it holds important clues about the origins of life on Earth.
A fast-moving visitor is approaching our cosmic neighborhood. Dubbed 2019 SX5, this near-Earth object is about the size of the Great Pyramid of Giza.
When 'Oumuamua passed through our solar system in 2017, no one could figure out where the object came from. But astronomers think they've worked out how Comet 2I/Borisov got here.
Polish scientists are developing a first-of-its-kind cubesat mission to Mars that could launch as early as 2022.
An Indian spacecraft may be orbiting the moon, but it's also gathering valuable data about other key players in our solar system.
