On Christmas Eve, NASA's Parker Solar Probe flew closer to the sun than any human-made object ever — a stunning technological feat that scientists liken to the historic Apollo moon landing in 1969. Now, we know it survived.

NASA's record-breaking Parker Solar Probe will smash its own personal bests for proximity to the sun and fastest speed by a human-made object when it whizzes past our star on Christmas Eve (Dec. 24). It is unlikely to get significantly closer to the sun before the end of its mission.

Due to a delay with SpaceX's Dragon capsule, NASA's Butch Wilmore and Suni Williams, who were meant to spend 10 days in space in June 2024, will now not return to Earth until late March 2025 at the earliest, NASA announced.

Io is the most volcanically active world in our solar system. Now, NASA scientists have revealed how and why.

"She still has one final gift for us, which is that she's now going to continue on as a weather station of sorts."

China's planned mission to bring rock samples to Earth from Mars would beat both NASA and the European Space Agency to the punch.

New Hubble Space Telescope images of a black hole-powered quasar reveal 'weird' structures and gigantic jets of energy that scientists are just beginning to explain.

"Budget overruns, bureaucratic malfeasance, congressional oversight, review-​board reckonings, the whole process of rethinking how to test a space telescope from the ground up: Webb had survived them all. One other factor, however, continued to create havoc with the budget and the launch timeline deep into the 2010s — what Menzel called 'stupid mistakes.'"

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.
