Mysterious cosmic signals of aliens challenge the scientific world

Radio signal of FRB 150215 was discovered by scientists on February 15, 2015 but so far, its origin remains one of the biggest mysteries of astrophysics.

Radiofrequency, or fast-flashing (FRB), is a random, random wave of radio waves that makes it difficult to find and research them. Although it only lasted for a few milliseconds, the energy of these fast-wave explosions was really terrible, equal to the sum of the energy of the 500 suns combined. The origin of this short and radio wave is still a mystery for scientists. Many believe that this fast flash is the message sent by aliens to Earth.

FRB 150215 is the 22nd radio flashing (FRB) that scientists discovered in the past 10 years. Among them, FRB 150215 is the most bizarre and confusing flash that makes researchers curious.

In order to find out the origin of FRB 150215, scientists are constantly using telescopes and specialized devices to find the clues of FRB 150215 but every effort so far has not been rewarded.

With other FRB signals, scientists can use telescopes to find the origin of the signal. But with FRB150215, it leaves no trace, although it can be observed through several telescopes.

Dr Emily Petroff of the Dutch Radio Astronomical Institute said: "We spend a lot of time decoding FRB 150215. To trace the source of FRB 150215, 11 telescopes specialize in detecting energy gamma rays. High, optical, neutrino emission, radio waves . are deployed all over the world but there is no source, repetition rate recorded. "

Is this a message sent by aliens to Earth?

The more mysterious is to go to Earth, the flash of FRB 150215 must pass a few billion light-years across and must "pierce" through the thick "magnetic walls" of the Milky Way.

The strong magnetic field of the Milky Way can completely change the light of other radio waves but with FRB 150215 it is quite the opposite.

It is these special things that make some scientists hypothesize, FRB 150215 may be a powerful signal of aliens trying to communicate with humans on Earth.
