Search For Intelligent Aliens Near Bizarre Dimming Star Has Begun

RATE THIS! +19
Posted in Science on 21st Oct, 2015 12:46 AM by AlexMuller

Astronomers have begun using the Allen Telescope Array (ATA), a system of radio dishes about 300 miles (483 kilometers) northeast of San Francisco, to hunt for signals coming from the vicinity of KIC 8462852, a strange star that lies over 1,000 light-years from Earth.

 
NASA's Kepler space telescope found that KIC 8462852 dimmed oddly and dramatically several times over the past few years. The dimming events were far too substantial to be caused by a planet crossing the star's face, researchers say, and other possible explanations, such as an enormous dust cloud, don't add up, either. 
 
The leading hypothesis at the moment involves a swarm of comets that may have been sent careening toward KIC 8462852, possibly after a gravitational jostle by a passing star. But it's also possible, astronomers say, that the signal Kepler saw was caused by huge structures built by an alien civilization, say, a giant assortment of orbiting solar panels.
 
That latter possibility, remote though it may be, has put KIC 8462852 in the crosshairs of scientists who hunt for signals that may have been generated by intelligent aliens. "We are looking at it with the Allen Telescope Array," said Seth Shostak, a senior astronomer at the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California.
 
"No problem with that; I think we ought to, for sure," Shostak told Space.com. But, he added, people "should perhaps moderate their enthusiasm with the lessons of history."
