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.

Radio burst sending signals to earth from deep space: Study

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

You may soon be able to ride to the edge of space from Alaska in a Balloon Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune A company wants to use an advanced balloon to fly customers from Earth’s surface in Alaska to the highest reaches of the planet’s atmosphere. Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune,  The Anchorage Daily News  reported on Sunday. The balloon rides will be manned by a flight crew taking eight passengers in a pressurized capsule suspended beneath a hydrogen balloon the size of a football stadium. Each passenger could pay an estimated $125,000 for a six-hour journey. Mark Lester, CEO of Alaska Aerospace Corp., said the high-altitude rides will be available from Kodiak in a few years and will ...

Committee recommends review of planetary protection policies

Committee recommends review of planetary protection policies WASHINGTON — The NASA Advisory Council has recommended that NASA review its existing planetary protection guidelines to balance the needs of science and exploration, an effort that could set the stage for a similar revision at the international level. The council, during a two-day meeting at NASA Headquarters Dec. 10–11, adopted a recommendation calling on NASA to establish an interdisciplinary committee of experts to review the agency’s current requirements for preventing contamination of other worlds by NASA spacecraft as well as any contamination of the Earth by materials brought back from those worlds. “NASA should establish a multidisciplinary task force of experts from industry, the scientific community, and relevant government agencies, to develop U.S. policies that properly balance the legitimate need to protect against the harmful contamination of the Earth or other celestial bodies with the scientific, social, and e...

Surprise! There's more water on Jupiter than anyone thought

Surprise! There's more water on Jupiter than anyone thought Jupiter  appears to have more water than anyone expected. Newly released data from  NASA's Juno probe shows that water may make up about 0.25% of the molecules in the atmosphere over Jupiter's equator. While that doesn't sound like much, the calculation is based on a prevalence of water's components, hydrogen and oxygen, three times more than at the sun. The new measurements Juno obtained are much higher than a previous mission suggested. The surprise result has scientists delving deep again into results from  NASA's Galileo mission to Jupiter , which obtained drier results in 1995 when engineers deliberately threw the spacecraft into Jupiter's atmosphere. (Galileo was low on fuel and NASA didn't want to take the chance, even if it was a slight one, of the spacecraft accidentally crashing on a potentially habitable icy moon.) Reconciling the results from Galileo and Juno is key for sc...
