A study published in The Astrophysical Journal identifies a new class of exoplanets – Hycean worlds – that could support life different from that on Earth.
Details
These planets are about 2.6 times the size of Earth, have temperatures about 200 degrees Celsius and planet-wide oceans. These could support microbial underwater life.
Exoplanets are planets that orbit a star other than our sun. The prefix exo comes from the Greek and means outside; these worlds are far, far outside our own solar system.
