NASA scientists had been looking for evidence of alien life on planets that lie far from the earth. Scientists believe that the alien will be found in 20 years, despite the evidence that has been found so far do not show a proof of intelligent alien life. This study states that there are about 100 billion galaxies which led to an understanding that life may not only exist on earth.
Data from NASA’s WISE infrared telescope observatory plays an important role as a source of information for scientists. Jason T, assistant professor of astronomy and astrophysics at Penn State Center for Expoplanets and inhabited world, stating that the core idea of the scientists are advanced alien civilization could be detected at mid-infrared wavelengths.
“The idea behind our research is that, if an entire galaxy had been colonized by an advanced spacefaring civilization, the energy produced by that civilization’s technologies would be detectable in mid-infrared wavelengths — exactly the radiation that the WISE satellite was designed to detect for other astronomical purposes,” stated Jason T. Write lead investigator and assistant professor of astronomy and astrophysics at Penn State’s Center for Expoplanets and Habitable Worlds.
Infrared detection was first suggested by Freeman Dyson , a physicist who theorized in a published paper that a sophisticated alien civilization would likely use most of its sun’s energy in which the process causes emission of light outward in slight amount that intensify levels of infrared radiation. The data taken from NASA’s WISE satellite made it clear that Dyson’s theory is attainable.
“Whether an advanced spacefaring civilization uses the large amounts of energy from its galaxy’s stars to power computers, space flight, communication, or something we can’t yet imagine, fundamental thermodynamics tells us that this energy must be radiated away as heat in the mid-infrared wavelengths,” Wright stated. “This same basic physics causes your computer to radiate heat while it is turned on.”
Finding alien life may have resulted negative, yet 50 galaxies showing high levels of mid-infrared radiation has caught researcher’s attention. Scientist are headed towards investigating the source of such inconsistency.
“This research is a significant expansion of earlier work in this area,” stated Brendan Mullan, director of the Buhl Planetarium at Pittsburgh’s Carnegie Science Center. “The only previous study of civilizations in other galaxies looked at only 100 or so galaxies, and wasn’t looking for the heat they emit. This is new ground.”
