Exoplanets: As the Data Streams Back… the Picture Comes In

China is now focusing on the search for a planet like Earth, using the Earth 2.0 Telescope (ET). Astronomer Jian Ge believes his team can find 17

In recent exoplanet news: ● China is now focusing on a search for a planet like Earth: Most likely, such a planet does exist, but in the relatively nascent field of exoplanet research, no one has yet been able to find it. That is not for lack of trying. Kepler spent nine years searching over 150,000 stars, and while it detected almost 3,000 new exoplanets, none met the criteria of being Earth-sized in the habitable zone of a sun-like star. Bad luck might have played a role – the new paper’s authors even calculated that statistically, Kepler probably should have found at least one Earth-sized planet in a habitable zone.

Some Cold Giant Planets May Be Habitable, Researchers Say

Life could exist outside the expected habitable zone if a massive planet can hang onto insulating gases in its atmosphere

Rocky exoplanets with an atmosphere of hydrogen and helium gases could have liquid water on the surface, like Jupiter’s moon Europa, and could thus host life. The question is whether the surface water sticks around long on “cold super-Earths,” that are ten times the mass of our planet: Now, new calculations described in a paper published Monday in the journal Nature Astronomy suggest that the surface conditions of these worlds could have been temperate for more than enough time for life—for 5 billion to 8 billion years. Earth is only about 4.5 billion years old, by comparison, and life emerged here about 3.7 billion years ago.
