Spotting DMPP-7 b: The Wobble (Radial Velocity) Method

Astronomers found a giant planet 331 light-years away — without ever taking its picture! They used the wobble method, which detects tiny movements in a star caused by a planet's gravity. Find out how this clever trick revealed a world called DMPP-7 b.

KIC 9663113 b: A World Where Water Might Be Possible
More than 5,000 light-years away, a planet called KIC 9663113 b orbits a star a lot like our Sun. Scientists think it might be in just the right spot for liquid water — but there are still many big questions to answer.
TOI-808 b: A New World Around TOI-808
A newly confirmed planet called TOI-808 b orbits its star in less than 10 days and reaches temperatures hot enough to melt metal. Scientists are still puzzling out how this scorching world ended up so close to its star — and what it can teach us about planets beyond our solar system.
How Far Away Is GJ 1061 c?
GJ 1061 c is a planet just 12 light-years away — practically next door in space! But even the fastest spacecraft ever built would take around 18,000 years to get there. Find out what we know about this super-Earth and its tiny, dim star.
TOI-4898 b: Getting to Know a Mini-Neptune
TOI-4898 b is a strange world 322 light-years away that doesn't look like anything in our solar system. It's bigger than Earth but smaller than Neptune, and scientists think it might have a thick atmosphere and a deep layer of icy material hidden inside.
