NASA Detects Water on Five Planets

But that's no indication of alien life

Astronaut John Grunsfeld performs work while participating in the first of five scheduled spacewalks while servicing the Hubble Space Telescope on May 14, 2009 in Space.

NASA’s Hubble Telescope has discovered signs of water vapor on five Jupiter-sized planets outside the solar system.

But the fiery planets are not suitable for life, sitting too close to their respective suns to sustain water on the surface, scientists say. The telescope’s Wide Field Camera 3, which measures near-infrared light, detected traces of water by observing each planet as it passed in front its sun, the Los Angeles Times reports.

Scientists expect the James Webb Telescope, which plans to launch in 2018, will be stronger than the Hubble and able to spot signs of water on smaller planets similar to Earth.

Perhaps then, is there life or fossils in other planets? But, isn’t the emergence and maintenance of life a process of radical contingency ? That is, is a unique and unrepeatable past totally necessary? Or rather, does life emerge through space like mushrooms in the field when some conditions are present? So, how many conditions are necessary:  three, four, trillions, infinite? Only one, water or any sort of God? Is God the word  that means infinite conditions? And, how did the life that emerge in a given conditions resist when switching to a different  moment? How does life resist time itself, the effects of entropy? Anyway, is it possible for human beings to recognise a simpler life than their own brain only? On the other hand, is it possible to recognise a complex life than their brain, is this the extra-terrestrial life that some people are searching unsuccessfully? But, is there an origin of life or would it be as finding a cut in the material history of the universe, an infinite void that human language patches now? Is this the same cut between life and death?  What would you and me be without this cut? Along these lines, scientific-humanistic book, a public preview in goo.gl/IUlSMu  Just another suggestion.
