On the surface of a young star in the constellation of Orion recorded a flash, which, when compared with flashes of this kind occurring on the sun, exceeds the power of an incredible 10 billion times. Photographs of the phenomenon were presented in the Astrophysical Journal.
“We were studying the stars close to us in order to find out how our solar system was formed. Previously, we have never witnessed the appearance of such powerful flashes on young luminaries. With their appearance, we had the opportunity to study well the physical properties of these space objects, ”said Steve Meirs, employee of the East Asian Observatory in Hawaii (United States of America).
On the Sun, flashes occur at times, which are powerful, lumps of energy produced by light, heat, and X-rays. Such phenomena can be very dangerous for radio communications and satellites, astronauts who are in orbit, who are many times more susceptible to radiation hazardous to health, are also affected.
Sometimes these outbreaks acquire simply incredible power, and, accordingly, bring with them a lot of trouble. As it happened, for example, back in 1859, when the geomagnetic storm set a record that has not yet been broken. The consequences were the failure of telegraph systems throughout Europe and North America, the appearance of the northern lights in almost all corners of the globe. Experts have determined that during this historical phenomenon about 10 yo-tojoules (10 to 25 degrees) of energy were allocated, and this is two dozen times more than when a giant meteorite fell 65 million years ago, which later destroyed dinosaurs. Powerful storms also occurred in 1921 and 1960, causing great communication problems.
In the spring of 2012, scientists discovered several hundred G-class stars, to which, incidentally, our Sun also belongs, and flashes were recorded on their surface, exceeding the geomagnetic storm of 1859 by several million times. Then the terrible thought occurred to the experts that similar events could take place on the Sun.
Watching the still very young and small-sized stars inside the Orion Nebula, the team of Steve Meirs suddenly was surprised to realize that much more powerful flashes could occur there.
In November 2016, an unusual high-brightness flash was recorded next to the newborn star JW 566, which is 1500 light-years away from Earth. Using all available tools, scientists have calculated the power of the flash, which exceeded the solar one 10 billion times.
Science has yet to figure out how often such powerful flashes occur on the surface of JW 566 and other young luminaries. In addition, you need to find out what processes occurring in the upper layers of their atmosphere, provoke these supergiant emissions of energy. Meirs and his colleagues hope that answers to these questions will be received next year.
