No Alien Radio Signals Spotted in Space Irregularity

Update Date: Nov 10, 2015 09:05 AM EST

According to Search for Extraterrestrial Intelligence Institute, the star system that had led to the speculation of ET life has given nothing more than silence on the radio. For two weeks, they have been observing an irregular light pattern in a star system. Also known as Tabby's Star or KIC 8462852, this star system has been under observation because of its uncommon light variation. This system was discovered by Planet Hunters, an astronomy crowdsourcing site, a few years back. As per the data that was collected from NASA's Kepler telescope, the light from this star system is known to sometimes drop by 20%. This star is located some 1500 light years away, between Lyra and Cygnus constellations. SETI started investigating the light source after procuring data from Kepler team, who is on a mission to find earth like planets by observing the light patterns to signify if a planet is passing by, after the scrutinized data revealed an irregular light pattern, reports CNN.

SETI has so far not found any radio signals that the institute is monitoring using the Allen Telescope Array, that uses large number of small dishes that studies the wavelength. This telescope is located in the California's Cascade mountains and looks for two type of signals. First type of signal is a narrow-band which emits the "hailing signal", something that a society is likely to use to proclaim its existence. These are the signals that are most habitually pursued in radio experiments. The second type of signal is called the broadband-signal that is likely to be there if an alien structure is present in the star system, as per Q13 Fox.

Even though nothing has been found so far, senior astronomer at SETI, Seth Shostak said that not all hope is lost. He told CNN, "There is estimated to be in our galaxy alone a trillion planets. And we can see 100 billion galaxies. It's believed that one in 10 stars may have a habitable world capable of supporting life. That's a lot of real estate", reported Newsmax
