What might JWST reveal about TRAPPIST-1?

We spoke with the scientists leading the first observations of TRAPPIST-1 using the James Webb Space Telescope (JWST) in order to understand what mysteries their observations will help unlock.

A little too close for comfort

From gas orbiting a supermassive black hole to asteroids orbiting near the Earth, sometimes the vastness of space can feel a bit tight.

When will we explore Enceladus to find alien life?

While NASA will launch Dragonfly later this decade to Titan, another potentially habitable moon of Saturn, no space agency is currently funding a mission to Enceladus.
