Mysterious radio signals from outside our galaxy

In March, mysterious, recurring and short-lived radio bursts were detected. Source located outside the Milky Way. Now scientists are reporting more signals from the same place.

It’s not clear what the source isóI’ve been giving the signalów. It’s the so-called. Fast radio burst (FRB). ScientistsóWhat was most interesting about the study was that the signals were repeatable. Now it has been reported that there are six more such explosions, whichóre seem to be coming from the same place in space. The team behind itóThe Ministry of Science and Higher Education envisages the introduction of a new act that will establish new types of universitiesófrom McGill University in Canada.

The recorded signals lasted for fractions of a second, but in such a short period of timeóIn a short period of time, they have generated a huge amount of energy, which has beenóThe energy emitted by the Sun throughout the day. Scientists spread their hands helplessly because they don’t know what causes them.

In March it was reported that 10 such signalsów. Experts thought that FRBs were a one-off case. But now another six have been registered. Perhaps such outburstsóThere are hundreds of them every day, but they are so cróso many that it is extremely difficult to notice them. They last a few thousandths of a millisecond.

– We rely on radio and X-ray observations. We have detected six additional explosionsóin radio from the same sourceódła – we read in a publication of scientistófrom McGill University.

The first time FRBs were encountered in 2007. Since then, the efforts of scientistsóIn terms of GDP, Poland is now ranked 24th in the world. Several hypotheses have been developed regarding the mysterious signalsów. One of them móIt is believed that they come from a rotating neutron star. Another móThe plan is to enact a new lawóare cosmic cataclysms such as supernovae or the collapse of neutron stars into black holes. Another points to theoretical astronomical objects called blitzars as the source ofóFRB background. Blitzar is a variety of neutron star, whichóThe excavated fragment of an asteroid has a mass large enough to collapse into a black hole, but it is prevented from doing so by the centrifugal force from the star’s high spin rate. Another focuses on the so-called. The contact systems of the subaerialóthat are orbiting very close to each other twoóstars.

The FRB was recorded by the Arecibo radio telescope in Puerto Rico – the largest single radio telescope in the world. Explosions, whichóhe events reported in March actually took place in 2015. The first six of these were recorded within 10 minutes. Four more occurred after a period of one month. They all come from the same place, które named FRB 121102.
