"Although water vapor can exist in the atmosphere, liquid water namely oceans would not exist on the surface of this planet," he said. Recent observations from the Thick clouds with not a chink between them hide a huge, but dim sun. Due to the lack of any water in its liquid form, combined with a high temperature and pressure, it is highly unlikely that life could exist on this planet, but there is a possibility. Only negligible fluctuations in the level of light indicate transitions from nights to days and nights again. The max value is 1 meaning its an ellipse. measured in milliarcseconds. exoplanets is important partly because most lifeforms on Earth need water to survive. N.p., 21 Feb. 2012. Then, they speculate that it gradually migrated inwards, melting the ice and, thus, accounting for the presence of liquid water. Astronomers have determined that the atmosphere of super-Earth Gliese 1214 b is likely water-rich. To use this method, the observation point must be somewhat edge on in order to observe a planetary eclipse of the host star. 22 Oct. 2013. The Ecliptic is the path that the Earth takes as it orbits the Sun. A nearby alien planet six times the size of the Earth is covered with a water-rich atmosphere that includes a strange "plasma form" of water, scientists say.
