The signal is coming from a red dwarf star known as Ross 128 which is 2,800 times dimmer than the sun and is not known to have any planet around it, adding more to the mystery.

Astronomers at the University of Puerto Rico detected the freaky radio signals in May. Researchers said a small and dim red dwarf star called Ross 128 (GJ 447) is sending out odd signals.

In a development that has resulted in much excitement among scientists, unusual signals have been detected coming from a dwarf star that is located around 11 light years from earth.

The "strange" radio signals were detected using the Arecibo Observatory, which is a massive radio telescope built inside of a Puerto Rican sinkhole.

However, Abel Mendez, an astrobiologist at the University of Puerto Rico at Arecibo said that the possibility that the odd signals came from intelligent extraterrestrial life can not be ruled out yet.

The signals were picked up in "almost periodic" bursts and further investigation is required to figure out the original source of the signals, researchers said.

He told Business Insider: "The SETI [Search for Extraterrestrial Intelligence] groups are aware of the signals".

According to Mendez, this type of emission of signals from satellites has not been seen before, and he described it as "very peculiar", he stated in a blog post.

"Therefore, we have a mystery here and the three main explanations are as good as any at this moment", the professor said.

"Success will be to find the signal again in the star but not in its surroundings".

Seth Shostak, senior astronomer at the SETI Institute, said that they are "well aware of the signals" and hope to use California's powerful Allen Telescope Array to "check them out".
