Meet the TOI-1136 System: 6 Worlds Around One Star
About 276 light-years away, a star called TOI-1136 has six planets circling around it. One of them, TOI-1136 f, is almost four times wider than Earth — and scientists are using this crowded system to learn how planet families are built.
How Did We Find DMPP-6 c?
Scientists can't photograph DMPP-6 c, but they still proved it exists — 178 light-years away! Find out how a tiny starlight wobble and a cool trick called the Doppler effect helped astronomers uncover this mysterious world bigger than Earth but smaller than Neptune.
Could Kepler-991 b Be Friendly to Life?
Kepler-991 b is a planet more than 1,200 light-years away that scientists discovered in 2016. It's bigger than Earth, orbits a calm orange star, and has a temperature that might not rule out life — but there's still a lot we don't know.
