K2-18b has long been considered the premier candidate for a "hycean planet" — an ocean world bigger than Earth with a hydrogen-rich atmosphere. Hycean planets, much like Earth, ...

The exoplanet known as K2-18b was first discovered in 2015 more than 120 light-years from Earth during NASA's planet-hunting K2 mission.. A whopping 8.6 times bigger than Earth, K2-18b orbits a ...

Even if K2-18b doesn't ultimately prove to host life, the techniques and insights gained from studying it will be useful for future investigations of other potentially habitable worlds, said Musilova.

K2-18b — which is eight times the size of Earth and 124 light-years away — shows signs of the unique molecule dimethyl sulfide, according to a new study published in the Astrophysical Journal ...

K2-18b is around 8.6 times as massive as Earth, putting it smaller than Neptune but obviously larger than our own planet, according to NASA.

Recently, a group of scientists claimed they found possible signs of life on a planet called K2-18b. The news made headlines. Researchers said they'd detected sulphur-based gases that, on Earth ...

The planet in question, K2-18b, was discovered in 2015 by NASA's Kepler mission, which revealed that planets outside our solar system are so common that they outnumber stars.

K2-18b, an exoplanet 120 light-years away, may be the best hope to confirm that life exists beyond Earth. Here's what to know. News Sports Autos Entertainment Advertise Obituaries eNewspaper Legals.
