Find out the source of 'aliens'

Scientists have recently traced the source of the mysterious signal over the past decade, in a galaxy 3 billion light-years from Earth.

According to the Daily Mail, astronomers have had to "headache" for a decade since they first caught the mysterious signal from the universe.

Astronomers have discovered the source of the mysterious signal over the past decade.

Some even argue that this signal is a sign of aliens trying to contact Earth.

Specifically, fast radio waves (FRB) have only appeared 18 times since 2007 and are one of the largest astronomical mysteries. The FRB wave has a very strong intensity but only lasts no more than 1/1000 seconds.

This signal source has recently been identified by astronomers as originating from a dwarf galaxy more than 3 billion light-years from Earth.

"Now, we know these signals come from a dwarf galaxy 3 billion light-years away, " said Dr. Shami Chatterjee from Cornell University. " This is a big step in understanding this phenomenon."

The team used the extremely large glass complex Karl Jansky (VLA) in New Mexico and the Arecibo telescope in Puerto Rico to specifically identify the signal source.

The mysterious signal could be the beam of matter coming from the rim of a supermassive black hole.

"In the past, there were some explanations that the origin of the FRB came from within or near the Milky Way. However, this new finding excluded the above theory ," said Dr. Shriharsh Tendulkar, a member of the group. McGill University research in Montreal, Canada, said.

Despite the location of the source of FRB, astronomers still do not know what it is. This phenomenon could be a super-thick Neutron star with a strong magnetic field or a beam of matter fired from the rim of a supermassive black hole.

Dr. Shami Chatterjee said the team still had a lot of work to do to better understand the "aliens" signal source as well as why this signal appeared.
