Spotting LHS 1903 d: The Transit Method

In 2026, scientists discovered a new planet called LHS 1903 d, orbiting a dim red star 116 light-years away. Find out how astronomers used tiny dips in starlight to spot this distant world — and what those dips reveal about the planet's size and orbit.

Meet LHS 1903 c: A Mini-Neptune Around a Small Red Star

LHS 1903 c is a planet unlike anything in our solar system — bigger than Earth but smaller than Neptune, orbiting a dim red star so closely that one year there lasts less than a week. Find out what scientists have learned about this strange, faraway world!

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.
TOI-1718 b: A New World Around TOI-1718
TOI-1718 b is a scorching hot planet nearly four times wider than Earth, racing around its star in less than six days. It belongs to a type of world that doesn't exist in our solar system — and scientists are just beginning to uncover its secrets.
How Long Would It Take to Reach Gl 725 A b?
Gl 725 A b is one of the closest exoplanets to Earth, but even at 11.5 light-years away, it would take our fastest spacecraft about 209,000 years to get there. Find out what that distance really means and what we know about this nearby world.
