The superterres could be poorer than expected water
NASA has just made an announcement that at first feels warmer. This is not the first time that Hubble detects water in the atmosphere of exoplanets as gas giants Wasp 12b and HD 209458b. But the measures have become precise enough to conflict with models of formation and migration of hot Jupiter. http://enjoycoloring.com/tag/halloween/ They are poorer in water than expected and this finding could be extended to superterres.
As far as we know, life needs water to appear and grow. The exobiologistes must have the means to detect the presence of water on an exoplanet before to seek to detect biosignatures or even technosignatures . With this program in mind, astronomers have of course tried to analyze the chemical composition of the atmosphere of exoplanets. But to find the traces of molecules of water in the spectrum of one of these atmospheres, place a telescope outside our own, otherwise the produced water vapor signal on Earth that will drown coming from another world.
