The findings brings astronomers a step closer to understanding the origins of these mysterious signals from outer space. They belch out across the cosmos without rhyme or reason, with no discernible pattern, making them incredibly hard to study. The recently detected FRB sends out bursts during a 90-day window, followed by 67 days of silence, in a loop that repeats every 157 days, the astronomers said.
The presence of a repeating pattern may indicate the bursts are linked to the orbit of a massive star, a neutron star or a black hole, the scientists said. It's thought they come from huge explosions happening in deep space that fade away in less than a second. If this observation is confirmed then it would be the first FRB spotted in our galaxy. FRBs are bursts of radio waves in space that last just a millisecond.

The signals have mystified scientists ever since the first FRB was found in 2007. "Further observations of a larger number of FRBs will be needed in order to obtain a clearer picture about these periodic sources and elucidate their origin.". Despite the relative consistency we still don't know their source. The FRB was first discovered in 2012 and was seen repeating in 2016 — but this study is the first to identify its pattern. Although this may seem eerily similar to the plot of Independence Day, the signals aren't thought to be coming from aliens ready to attack the planet. Elon Musk has said SpaceX's Starship rocket, which he hopes will put Americans on Mars, is now the company's "top priority". In other news, Pluto may be hiding a vast ancient ocean that formed 4.5billion years ago. Election Day could turn into "Election Week" with rise in mail ballots, Astronomers detect mysterious radio signals. 10 FEBRUARY 2020 .

Some have wondered if FRB's could be a message from aliens — and without more research, there's no way to know.
This FRB pattern is significantly longer than its 16-day counterpart, indicating the potential range for these types of emissions. Fast radio bursts (FRBs) are a space phenomenon that have baffled astronomers for years. Another theory links the pattern to periodic wobbles in the rotational axis of a highly magnetized neutron star. Do you think there is alien life out there? Boris Johnson announcement: What time is the PM's speech today, Monday November 2? Hundreds have been spotted, but only a handful have ever repeated themselves — and they appear to come from locations all over the universe. The repeating radio waves coming from one point in the sky have presented more questions than answers. "This is an exciting result as it is only the second system where we believe we see this modulation in burst activity," lead author Dr. Kaustubh Rajwade said in a news release.

Some scientists think the source of the repeating signal is 500 million light years in an area of active star formation. The Sun website is regulated by the Independent Press Standards Organisation (IPSO).

The repeating radio waves coming from one point in the sky have presented more questions than answers. Sophie Lewis is a social media producer and trending writer for CBS News, focusing on space and climate change. Scientists are puzzling over powerful, millisecond-long flashes of energy from deep space, known as “fast radio bursts,” that some think are alien signals. The signals are said to build up and then down again over a period of 16 days. One theory is that the radio wave eruptions could come from neutron stars, wobbling as they rotate. With more mail-in ballots, officials urge patience on election night, Americans and the right to vote: Why it's not easy for everyone, Why some mail-in ballots are rejected and how to make sure your vote counts. Kiyoshi Masui, an MIT assistant professor of physics, said: "This FRB we’re reporting now is like clockwork.

But the lengthy precession period makes this theory unlikely. First published on June 9, 2020 / 4:00 PM. Their study of the FRB was published Sunday in the journal Monthly Notices of the Royal Astronomical Society. Another theory links FRBs to neutron stars orbiting each other or a blackhole and passing material between them. Astronomers announced this weekend that they've detected a mysterious fast radio burst coming from a dwarf galaxy three billion light-years away. They were first picked up by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope in Canada. How do I vote in my state in the 2020 election?

In April, a signal that could have been an FRB was spotted coming from a magnetic star 30,000 light years from our planet. MICHELLE STARR .
The burst — known as an FRB — appears to be transmitting signals that reach Earth in a repeating, 157-day pattern, the group said.

An international team led by University of Manchester astronomers at the Jordell Bank Observatory was able to track emissions from FRB 121102, which has been studied for years.
This study has been published published in the journal Nature. "Detecting a periodicity provides an important constraint on the origin of the bursts and the activity cycles could argue against a precessing neutron star.".
