Scientists detect odd signals coming from dwarf star

It is located 11 light years away from Earth and is 2,800 times less radiant than the Sun.

Unusual signals emitted from a nearby star have been spotted by astronomers.

"We realised that there were some very peculiar signals in the 10-minute dynamic spectrum that we obtained from "Ross 128" (GJ 447), observed May 12", wrote professor Abel Mendez, planetary astrobiologist and director of the Planetary Habitability Laboratory at the University of Puerto Rico in a blog post.

Astronomers at the University of Puerto Ricohave detected mysterious radio signals coming from outer space.

Mr Mendez said that the signal was "almost periodic", and although it is unlikely that it originates from alien beings, it can not be ruled out.

As such, official alien hunters have been notified.

"We do not know the origin of these signals but there are three main possible explanations: they could be emissions from "Ross 128" similar to Type II solar flares, emissions from another object in the field of view of "Ross 128", or just burst from a high orbit satellite since low orbit satellites are quick to move out of the field of view", Mendez said. This finding has been revealed to SETI (Search for Extraterrestrial Intelligence) - an alien-hunting authority.

"The field of view of (Arecibo) is wide enough, so there is the possibility that the signals were caused not by the star but another object in the line of sight".

A senior astronomer at SETI Institute named Seth Shostak explained that they were well aware of the signals and they wish to use California's powerful Allen Telescope Array to examine them.

He said: "Success will be to find the signal again in the star but not in its surrounding [s]".
