Just 42 light-years away, a star called HD 40307 has at least five planets packed tightly around it. One of them is thousands of times heavier than Earth and blazing hot. What else is hiding in this crowded star family?
How Did We Find TOI-5788 c?
A planet called TOI-5788 c was discovered hundreds of light-years away using two clever tricks — catching its shadow as it crossed its star and watching the star wobble. Find out how scientists uncovered this hot, fast-moving world without ever seeing it directly.
WASP-47 c: A World Where Water Might Be Possible
WASP-47 c is a giant planet 864 light-years away that sits in the zone where liquid water could exist — but is it really a place where life might be possible? The answer is more surprising and complicated than you might think.
TOI-5605 b: A New World Around TOI-5605
Three hundred and ten light-years away, a planet called TOI-5605 b races around its star in less than six Earth days and reaches scorching temperatures. Scientists confirmed this fascinating world in 2026, and it is already helping us understand the amazing variety of planets across our galaxy.
GJ 1061 b: A World 12 Light-Years From Earth
GJ 1061 b is a rocky world almost exactly Earth's size, circling a cool red star just 12 light-years away. Scientists found it by watching the star wobble — and what they learned is pretty amazing.
