What’s out there? Deep space radio burst sending signals to earth every 157 days, study finds
FRBs are bursts of radio waves in space that last for a very short time, just a millisecond.
Astronomers and space scientists and even amateur alien theory enthusiasts around the world have for years tried to decipher signals that are received from space. It's a job profile that requires years of study, a good understanding of sound frequencies
Despite years of research, no concrete evidence of extraterrestrials sending signals to earth has been found yet. But now, a new study promises to pique interests of all space observers and alien theory enthusiasts around the world.
The study says a mysterious fast radio burst signal has been detected coming to earth from a dwarf galaxy that is three billion light-years away. The burst - known as an FRB - appears to be transmitting signals that reach earth every 157 days, reported CBS News.

The study says a mysterious fast radio burst signal has been detected coming to earth from a dwarf galaxy that is three billion light-years away. The burst - known as an FRB - appears to be transmitting signals that reach earth every 157 days, reported CBS News.
The study adds the discovery of such a signal is only the second time that scientists have identified an FRB that repeats in a pattern. Back in February, scientists had revealed that an object 500 million light-years away appears to transmit signals to earth every 16 days.
What are FRBs?
FRBs are bursts of radio waves in space that last for a very short time, just a millisecond. While many FRBs have been traced back to their home galaxies, scientists are yet to figure out the cause of such signals.
The study further added that emissions from FRB 121102 were tracked by a team of astronomers from the University of Manchester at the Jordell Bank Observatory.
As for the recently detected FRB, it sends out radio signals during a 90-day window and then follows it up with 67 days of silence. It's a loop that repeats every 157 days, said an astronomer studying the pattern.
The same FRB was first detected in 2012 and was seen repeating itself in 2016. The recent study was the first that was able to establish a pattern.
"This is an exciting result as it is only the second system where we believe we see this modulation in burst activity," Dr. Kaustubh Rajwade, lead author of the study, said in a news release.
"Detecting a periodicity provides an important constraint on the origin of the bursts and the activity cycles could argue against a precessing neutron star," he added
