Water found on five distant planets
December 5 , 2013
Scientists recently discovered water in the atmospheres of five plants outside our solar system.
"To actually detect the atmosphere of an exoplanet is extraordinarily difficult," Drake Deming of the University of Maryland said. "But we were able to pull out a very clear signal, and it is water." However, there doesn't seem to be any sign of life on any of the gas giants since they are too close to their suns.
Although, the plants are too hot for life, researchers said the Hubble discovery is a positive step in their search for better-suited planets. Moreover, this is the first time that such water vapor has been confirmed.
The discovery also "opens the door for comparing how much water is present in atmospheres on different kinds of exoplanets - for example, hotter versus cooler ones," a NASA scientist said.
