Astronomers say that a fast radio burst called FRB 150215 may be one of the most mysterious ever found.  Given the direction from space the FRB came from, scientists concluded that FRB 150215 should NOT have been detected because it had to travel through an extremely dense region of our galaxy in order to reach us. FRB 150215 has left experts completely baffled. While it can be observed to several telescopes, the FRB has NOT left any detectable signal or trace of light.

Is it possible that Aliens really are trying to contact Earth? According to experts, the latest intercepted alien signal is beyond fascinating.

Fast Radio Bursts or FRB’s were detected for the first time some 10 years ago. A Decade later, these enigmatic signals remain as one of the biggest mysteries in astrophysics.

The latest fast radio burst—called FRB150215 may be the most mysterious of them all.

FRB150215 was detected for the first time in 2015 by researchers from the Netherlands Institute for Radio Astronomy who have been trying to figure out where it came from. However, despite spending two years using telescopes to find more data about, experts say they are clueless about where this FRB might have originated from.

In an interview with Gizmodo, Emily Petroff, who is leading the study, said: “We spent a lot of time with a lot of telescopes to find anything associated with it.We got new wavelength windows we’ve never gotten before. We’re still trying to figure out where this one came from.”

Fast radio bursts (FRBs) are a high-energy astrophysical phenomenon of unknown origin manifested as a transient radio pulse lasting only a few milliseconds. Fast radio bursts are bright, unresolved (pointsource-like), broadband (spanning a large range of radio frequencies), millisecond flashes found in parts of the sky outside the Milky Way. Unlike many radio sources, the signal from a burst is detected in a short period of time with enough strength to stand out from the noise floor. The burst usually appears as a single spike of energy without any change in its strength over time.

However, the interesting part is that experts are not sure what could produce such a short and sharp burst.

There are several theories and they could be anything from stars colliding to artificially created messages by advanced alien beings.

In the last decade, 22 Fast Radio Bursts have been detected, however, astronomers believe that there could be up to 2,000 FRBs in the universe EVERY day.

Normally, experts are able to use radio telescopes to pinpoint the likely source of FRBs. However, FRB 150215 has left the Dutch team completely baffled. While it can be observed to several telescopes, the FRB has NOT left any detectable signal or trace of light.

In a scientific paper published in arXiv, scientists wrote: “The burst was followed up with 11 telescopes to search for radio, optical, X-ray, gamma-ray, and neutrino emission. Neither transient nor variable emission was found to be associated with the burst, and no repeat pulses have been observed in 17.25 hours of observing.”

What is even more mysterious is the fact that given the direction from space the FRB came from, scientists concluded that FRB 150215 should NOT have been detected, because it had to travel through an extremely dense region of our galaxy in order to reach us.

Scientists explain that our galaxies magnetic field should have altered the way light from the FRB traveled, but it did not.

Ms. Petroff added: “It probably traveled through some kind of hole in the Milky Way that makes it easy to find compared to normal searches in the galaxy.”
