NASA's Kepler space telescope has detected some strange signals coming from a star located almost 1,500 light-years away from earth. Now scientists speculate that those strange signals could be of alien life in our universe.

Kepler noticed certain dips in brightness of the star known as KIC 8462852 in the past six years. Astronomers after studying the data found that those dips were quite unusual and were very much different from orbiting planets passing in front.

At their first look at the data everything appeared to be unreal, they all were scratching their heads, Yale University astronomer Tabetha Boyajian told the New Scientist.

"Kepler for years has been giving us a catalog of over 1,000 extra-solar planets and this is the first oddball out of hundreds of thousands of stars scanned. This is the first one that does not fit the usual scenario", said CBS News science contributor Michio Kaku.

Boyajian and his team concluded that the reason behind dips was most likely exocomets that pass close to the star. They said the exocomets would have broken by the stars gravity, resulting in huge amounts of dust and gas, according to New Scientist.

Boyajian shared her data with Penn State astronomer Jason Wright, who helped to develop a protocol for find any evidence of alien civilization.

Wright told The Atlantic that the unusual light pattern from the star indicates that there is a swarm of megastructures that could be taking energy from the star.

Wright along with two other astronomers are planning to point a massive radio dish at the star and will be sending signals to check if it can pick up signals associated with technological activity.
