Latest Research Shows Milky Way Could Be Teeming With Alien Life

Researchers presently constant that submit are potentially tens of billions of planets in the Rich Way galaxy everywhere alien life may perhaps exist.

Scientists from College of California, Berkeley, and College of Hawaii, Manoa second hand data from NASA's Kepler space diminish and the W. M. Keck Observatory to statistically detect that one in five Sun-like stars in our galaxy sustain Earth-sized planets that may perhaps host life. Erik Petigura, a UC Berkeley graduate learner who led the study's data study, explains in a press release issued by the W. M. Keck Observatory, "Like this means is, a long time ago you measure up at the thousands of stars in the night sky, the near sun-like term among an Earth-size planet in its habitable zone is most probably easily twelve light living out cold and can be seen among the bare eye. That is unanticipated."

Andrew Howard, an astronomer among the Found for Astronomy at the College of Hawaii, adds, "For NASA, this number - that every fifth term has a planet more willingly adjoining Burrow - is accurately means, the same as progeny missions to Kepler behest try to take an existing picture of a planet, and the vastness of the diminish they sustain to tell somebody to depends on how fail the near Earth-size planets are."

The research bash included UC Berkeley schoolteacher of astronomy Gfrey Marcy who explained on the program "PBS Newshour":

Of course, the properties of a planet that physique it correct for life is -- the essentials sustain to be water, the same as our own human bodies are complete of water. All life-forms on the Burrow depend on water. And so we bring -- most likely incorrectly -- that life out submit among the stars would furthermore depend on liquid water.

But Marcy furthermore cautions that not all these planets are robotically ardent to life. He explains, "Convinced may sustain stumpy atmospheres, invention it so hot at the floor that DNA-like molecules would not stoppage. Others may sustain gruff surfaces that may perhaps yachting marina liquid water correct for occupation organisms... We don't concede what size of planet types and their environments are correct for life."

The team's research was published on November 4 in the chronicle "Record of the Confusion Ivory tower of Sciences".
