About 88 light-years away, a star called HD 158259 has five planets packed surprisingly close together — all zooming around in just days! Scientists are still piecing together what these crowded worlds are made of and why they orbit in such a tight, orderly chain.
Spotting TOI-5624 e: The Transit Method
A planet called TOI-5624 e was discovered 332 light-years away using a clever trick — scientists watched for tiny dips in starlight to find a world they could never see directly. Find out how this hot, mysterious planet was spotted and what scientists have learned so far.
Is Kepler-705 b in the Goldilocks Zone?
Kepler-705 b is a planet 903 light-years away, and its estimated temperature puts it right at the edge of the zone where liquid water could exist. But does that make it a good place for life? The answer might surprise you.
Say Hello to TOI-5624 b, a Mini-Neptune
TOI-5624 b is a planet 332 light-years away that completes a full orbit in just 3.39 days and reaches temperatures hotter than Venus! It belongs to a type of planet called a mini-Neptune — and our solar system doesn't have a single one.
How Far Away Is YZ Cet d?
YZ Cet d is a planet almost exactly the same size as Earth, but it's 12.1 light-years away — and getting there would take over 200,000 years even in our fastest spacecraft. Find out what we know about this strange, nearby world.
