Will the hazy exoplanet GJ 1214b be the spa-resort getaway of the year 2100? BBC reports:
Astronomers have claimed the existence of a new class of planet: a “water-world” with a thick, steamy atmosphere. The exoplanet GJ 1214b, just 40 light-years away, is a so-called “Super Earth” – bigger than our planet, but smaller than gas giants such as Jupiter.
Observations using the Hubble telescope now seem to confirm that a large fraction of its mass is water. The planet’s high temperatures suggest exotic materials might exist there.
