TOI-5789 b: A Planet We Cannot See Directly
Scientists have never taken a photo of TOI-5789 b, yet they know it exists, how big it is, and how scorching hot it gets. Find out how astronomers use tiny wobbles and faint dips in starlight to uncover worlds 66.7 light-years away.
Could TOI-2257 b Be Friendly to Life?
TOI-2257 b is a planet 188 light-years away that sits in the zone where liquid water might be possible. Scientists don't know yet if it could support life, but the clues so far make it one of the most interesting worlds worth watching.
Say Hello to TOI-5789 e, a Mini-Neptune
Meet TOI-5789 e, a planet more than three times wider than Earth that completes a full year in just 63 days! Scientists confirmed it in 2026, and studying it helps us understand why so many planets in the universe turn out bigger and gassier than our own.
How Long Would It Take to Reach Barnard d?
Barnard d is one of the closest exoplanets to Earth, but even the fastest spacecraft ever built would take thousands of years to get there. Find out how far six light-years really is and what this small, scorching world is actually like.
