Exoplanet news, features and articles

There are estimated to be trillions and trillions of planets orbiting the stars beyond our solar system. These alien worlds are called exoplanets, and Live Science is as curious as you are about what might be on them.
That's why our expert writers and editors track interstellar research, whether it's the discovery of a new class of exoplanet, a mirror-like exoplanet that "shouldn't exist," or the possibility of the first exoplanet outside the Milky Way. So whether it’s extreme exoplanets or just memorable facts, get the latest exoplanet news, features and articles here.

Aimed at the nearby star PDS 70, the James Webb Space Telescope is watching newborn planets take shape before our eyes in uprecedented detail.

Newly discovered super-Earth orbits in and out of its star's habitable zone. Could life survive its extreme climate?
By Keith Cooper published
The climate on such a world must be beyond bizarre.

'Supersonic jetstream' with winds 130 times faster than a Category 5 hurricane spotted in the Milky Way
By Harry Baker published
The record-breaking winds are circling the nearby "puffy" exoplanet WASP-127b, and are traveling six times faster than the alien world spins.

'Mathematically perfect' star system discovered 105 light-years from Earth may still be in its infancy. Could that change its prospects for life?
By Jenna Ahart published
Once thought to be 8 billion years old, the star HD 110067 — famous for its six synchronized exoplanets — may be only 2.5 billion years old, new research suggests.

Surprise discovery in alien planet's atmosphere could upend decades of planet formation theory
By Sharmila Kuthunur published
The odd atmosphere of a fledgling exoplanet is causing astronomers to question leading theories of how planets form.

Nearby exoplanet has grown a tail 44 times longer than Earth — and it's acting like a giant 'stellar windsock'
By Harry Baker published
Researchers have detected a giant tail of gas leaking from an exoplanet near Earth. The giant structure, which is up to 350,000 miles long, is being blown away from the alien world by stellar gusts, allowing researchers to use it like a windsock.

'Baby' exoplanet, equivalent to 2-week-old infant, is the youngest alien world ever spotted — and it's orbiting a wonky star
By Harry Baker published
A new study has identified an exoplanet that is just 3 million years old — around 1,500 times younger than Earth — alongside a misaligned protoplanetary disk that researchers cannot explain.
