Scientists have found that someone blocks signals from outer space

Scientists have discovered that someone blocks signals from spaceAfter the experiment it became clear that in the low frequency range without a radio signal.

The radio station (FRB) is a signal coming from an unknown source in deep space. They were registered in 2007. Since then, several dozens of such outbreaks have been reported.

The FRB is considered to be the consequence of the event, releasing a large amount of energy. They take only a few milliseconds and make it difficult to identify their source.

A team of scientists at the Australian University of Painting, led by Marcin Sokolowski, found that the FRB was not observed at low frequencies. The researchers sent the same patch with two telescopes: the MWA and the CSIRO Australian SKA Pathfinder. The latter was used to detect dozens of signals from the deep space, which was written by Nature. But at that time, like the ASKAP, they discovered a new FRB, but the other – the telescope did not mind.

"When the ASPAP sees these extremely bright events, and MWA – no, it indicates to us that there is something really unexpected, or that the fast cosmic system is not transmitted at low frequencies, or signals are blocked on the way to the ground," said Sokolovsky.

Scientists were able to track down one of the FRB dwarf galaxies over three billion light years from Earth. There was a repeating signal, which is very unusual. All other FRBs were one-off events and tracked their activity.
