According to astronomers 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 left experts completely baffled.
Is there any possibility that Aliens really are trying to contact Earth? According to experts, the latest intercepted alien signal is beyond fascinating.
Some 10 years ago, Fast Radio Bursts or FRB’s were detected for the first time. A Decade later, these enigmatic signals remain as one of the biggest mysteries in astrophysics.
The latest fast radio burst that is called FRB150215 may be the most mysterious of them all.
Researcher from the the Netherlands Institute for Radio Astronomy who have been trying to figure out where it came from have detected FRB150215 for the first time in 2015. 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.
The leader of the study, Emily Petroff, in an interview with Gizmodo, 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) present a high-energy astrophysical phenomenon of unknown origin that manifests as a transient radio pulse that last only a few milliseconds. They are bright, unresolved, broadband (spanning a large range of radio frequencies), millisecond flashes found in parts of the sky outside the Milky Way.
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, 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.
22 Fast Radio Bursts have been detected only in the last decade. 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. 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 said: “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.”
The 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 says: “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.”
