The stadium-sized asteroid 2020 XR is due to make its closest approach to Earth on record early on Dec. 4, and the encounter will be livestreamed for everyone to see.

Using Einstein's theory of general relativity, physicists found that clocks on the moon would run 56 microseconds faster than clocks on Earth. That finding will help future lunar missions navigate.

Canada will soon roll a rover onto the moon, and you can help name the pioneering machine.

This week, the James Webb Space Telescope zooms in on the iconic Sombrero Galaxy, revealing the first-ever mid-infrared observations of the hat-shaped wonder.

Was alien life in "hot water" on Mars billions of years ago? New evidence from the Martian meteorite "Black Beauty" suggests so.

Curiosity has just finished the latest leg of its 12-year Mars mission and will now set out to explore miles of web-like surface features left behind by ancient water on the Red Planet. The zig-zagging rocks could also provide clues about whether Mars once harbored extraterrestrial life.

An asteroid that fell to Earth and exploded above Canada in 2022 was only around 20 inches wide — the smallest space rock ever properly measured, researchers say.

An outburst of solar energy looks primed to hit Earth on Thursday, potentially bringing auroras to the northern U.S. on Thanksgiving and Black Friday.
