SCIENTISTS ANNOUNCE MYSTERIOUS RADIO WAVES REACH EARTH FROM OUTER SPACE

Astronomers have reported a mysterious radio burst also known as Fast Radio Bursts (FRBs) coming
from the same spot in deep space on a regular cycle returning “right on schedule’,
Fast Radio Bursts are radio signals which emit very short-duration bright radio pulses from deep space.
The first burst was detected in 2007 and their origins have since baffled experts
The new discovery of a repeating pattern from an FRB has helped scientists to “pin down the origin of its
location to something like a neutron star or even a black hole.”
According to reports, in June, 2020, University of Manchester researchers confirmed that a Fast Radio
Burst called FRB 121102 was not “just repeating but was doing so on a 157 day cycle.”
The researchers predicted it would “return sometime in July or August and that is exactly what
happened, according to new observations of the source of the burst.”
The FRB 121102 is said to be located in an “unknown dwarf galaxy about three billion light years away.”
In a related report, Chinese astronomers have predicted the current active cycle will end by September
9.”
In an article published in the Astronomer’s Telegram, “a team from the National Astronomy Observatory
of China used the 1,640ft Aperture Spherical radio telescope to monitor the location the busts and
predict it is actually on a 156.1 day cycle.”
The Chinese team predicted that the “active phase is due to end between August 31 and September 9 –
when a renewed 67 day silent phase is expected to begin.”
The report however noted that continued evidence thst there is still radio bursts coming from that
region of space after September 9 will “mean the burst has either evolved or the predictions are wrong.”
‘If the source is continuously on after the projected turning-off time, it suggests that the putative period
of the source is not real or has evolution,’ the team wrote.
FRB 121102: THE FIRST REGULAR RADIO BURST CYCLE FOUND
Fast radio bursts (FRBs) are brief, bright pulses of radio emissions from distant but so far unknown
sources.
Only one FRB has been found to repeat, an object known as FRB 121102 in a galaxy about three billion
light-years away.
More than 200 high-energy bursts have been observed coming from FRB 121102, since it was first
detected in 2012.
In June 2020 a team from the University of Manchester confirmed that the burst was happening on a
repeating and predictable cycle.
They discovered it went through a 90 day silent phase then a 67 day active period where burst could be
detected.
Nobody knows exactly what causes the bursts but predictions include a black hole system or a type of
neutron star called magnetars.
‘We encourage more follow-up monitoring efforts from other radio observatories.’
The Chinese team combined data from the original University of Manchester observations using the
Joddrell Bank Radio Telescope and more recent observations by the Max Planck Institute using the
Effelsberg 100m Radio Telescope.
Observations by the German team using the Effelsberg telescope up to 2020 found 36 bursts from the
source of FRB 121102 and led to a 161 day cycle prediction.
The Max Planck team predict the active period will end on October 14, 2020 – more than a month after
the end of the active period predicted by the Chinese team.
The Chinese team say their predictions are more recent and combine data from all previous studies to
create an accurate prediction of the end day of the active phase.
Researchers from the University of Manchester, who discovered the fact the burst was repeating at
scheduled intervals, predict it could come from a black hole.
Over the past four years, astronomers have used the 240ft Lovell Telescope to study one of these
unusual bursts – known as FRB 121102 – to look for patterns.
They found that at the time, in June, the source was off but should be back on before August 28 – a
prediction proved to be correct by recent observations.
This is only the second time an FRB has been shown to repeat – the first, known as FRB
180916.J10158+56, has a 16-day cycle.
The team say proving these bursts have a regular pattern helped the team rule out some origins for
these mysterious astronomical phenomenon.
