Scientists used data from both observatories, along with data from Nuclear Spectroscopic Telescope Array (NuSTAR), and Neil Gehrels Swift Observatory, to confirm measurements [...]
2 Min Read NASA Launches Research Program for Students to Explore Big Ideas NASA is now accepting concepts for a new research challenge. The Opportunities in Research, Business, Innovation, and Technology (ORBIT) challenge is a multi-phase innovation competition designed to empower university and college students to develop next-generation solutions that benefit life on Earth [...]
Photo of the Day What’s happening over that tree? Two very different things. On the left is the Andromeda galaxy, an object that is older than humanity and will last billions of years into the future. Andromeda (M31) is similar in size and shape to our own Milky Way Galaxy. On the right is [...]
After 25 years of continuous human presence in space, the International Space Station remains a training and proving ground for deep space missions, enabling NASA to focus on Artemis missions to the Moon and Mars. The orbiting laboratory is also a living archive of human experience, culture, and connection. Creating community Expedition 34 crew members [...]
