Higher latitudes on the moon with slopes facing the poles "are not only scientifically interesting but also pose less technical challenges for exploration in comparison with regions closer to the poles of the moon."

India's Aditya-L1 spacecraft captured detailed observations of a powerful solar flare last year, helping scientists better understand our star's eruptions.

A modest NASA space telescope with grand ambitions will soon launch into an orbit around Earth. Here's why scientists are excited about it.

NASA's Europa Clipper will fly past Mars today to adjust its trajectory and position itself for a critical phase of its 1.8-billion-mile (2.9-billion-kilometer) trek to the Jupiter system.

"Everyone in the United States relies on NOAA in their daily lives whether they realize it or not, something that will come into focus for many in the weeks and months ahead."

Astronauts in isolated space habitats could benefit from the intentional fostering of diverse microbes from humanity's evolutionary past, a new study suggests.
