In the early history of our solar system, scientists theorize that a Mars-sized object called Theia smashed into the infant Earth, vaporizing massive amounts of rock and blasting it into space. Some of that material coalesced into the Moon, where NASA’s Artemis program is returning humans, preparing for Mars, and shaping the future of space

NASA’s Hubble Space Telescope completed its 200,000th orbit around Earth on Sept. 19, marking another new milestone for an observatory that continues to transform our understanding of the universe. Hubble has traveled more than 5 billion miles around Earth over its 36-year lifetime, exceeding 1.7 million total observations. An observation completed on the day of

Using data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) observatory, astronomers have directly observed a giant star’s outflow, called a stellar wind, being captured by its compact companion and providing the power source for strong X-ray flares. The research is part of NASA’s exploration of the extreme universe to better understand how the

Though the spiral galaxy in this new image from the NASA/ESA Hubble Space Telescope seems serene, it hides a chaotic secret. This galaxy is NGC 4698, and it lies about 55 million light-years away in the constellation Virgo. It’s one of over a thousand galaxies in the Virgo Cluster, the nearest large cluster of galaxies bound together by

Astronomers have confirmed a world that’s less than a million years old as the youngest known planet, using data from NASA-funded archives. Called Elias 2-24 b, the baby planet is still whirling in its natal disk of dust and gas. “Our planet-formation models already struggled to explain the previous record holders for the youngest known
