117 light-years away, a star called HD 20781 has at least five planets orbiting around it! Scientists are learning how these worlds formed and why some planets zoom around their star in just five days. Could any of them be like Earth?
How Did We Find TOI-4513 b?
TOI-4513 b is a scorching hot planet 335 light-years away that no one has ever seen directly — so how do scientists know it exists? Clever starlight detective work using two cool methods cracked the case, and the answers are pretty amazing.
Is Kepler-452 b in the Goldilocks Zone?
Kepler-452 b is a faraway planet that circles a star very much like our Sun, taking 385 days to complete one orbit. Scientists think it sits in the Goldilocks Zone, but there is still so much we do not know about this mysterious world.
TOI-5624 d: A New World Around TOI-5624
Astronomers confirmed a new planet called TOI-5624 d in 2026, and it is a wild one — a scorching hot world that zips around its star in just 13.7 days! It is one of five planets in its system, and scientists are still figuring out what it is made of.
How Far Away Is YZ Cet b?
YZ Cet b is one of the closest exoplanets to Earth, sitting just 12.1 light-years away — but even at that short cosmic distance, it would take over 100,000 years to reach it with today's fastest spacecraft. Find out what makes this tiny, fast-moving world so fascinating.
