Artemis II was set to launch in February, but a leaky situation has caused a delay. Find out about the challenges NASA is facing with this moon mission.

NASA said Tuesday the Hubble Space Telescope has revealed a dramatic interplay of light and shadow in what’s called the Egg Nebula.

The discovery is just the latest to come from the asteroid sample, which dates back to the dawn of the solar system.

Mercury has long been cast as the solar system’s burnt-out rock, a relic too small and too close to the Sun to hold many surprises. That caricature is now collapsing. New analysis of NASA’s MESSENGER mission data points to a buried layer of diamonds up to about 16 kilometres,

From famous space missions to making air travel safer, NASA Glenn Research Center, celebrating its 85th anniversary, continues to impact the world, infinity and beyond.

NASA's Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) was built for the ambitious purpose of performing an all-sky survey. The data it collects from more than 450 million galaxies and 100 million stars in the Milky Way over its two-year mission will help scientists explore the origins of the universe and its evolution over time.
