A "superflare" phenomenon, or eruption, releases a star's intense and sudden energy. It could happen to our sun within a century from now. and may have a serious impact on the Earth's atmosphere
Previously, scientists believed that A super-flare energy eruption that is only more intense than thousands of solar storms. It is only found in young stars that rotate rapidly around themselves. until a high level of electromagnetic movement Not for a star that is quite old and rotates slowly like the sun.
The 11-year solar cycle occurs because the planets are aligned.

Dr. Yuta Nozu, an astronomer at the University of Colorado. US Boulder Campus A recent study published in The Astrophysical Journal states that the results of an analysis of superflare phenomena occurring in deep space. which the Kepler space telescope has recorded several times. suggesting that sun-like stars can also emit energy at the level of superflares.
“Superflare is a rare phenomenon. It is also less common for slow-rotating stars like the Sun than fast-rotating, young stars. however There is a chance that Earth will be affected by the sun's superflare in about a hundred years," said Dr Nozu.
The results of the analysis of astronomical data above indicate that There are 43 Sun-like stars that have erupted at the level of superflare in the past. This extreme energy release occurs on average every 200-300 years.
Several previous studies have indicated that Solar flares can destroy the technology networks that form the world's infrastructure, such as telecommunication systems, GPS, power distribution systems. as well as potentially destroying the Earth's atmosphere to be thinner until harmful radiation in space escapes
however Dr Nozu also stated that more studies are still needed. To confirm the possibility that the world will be endangered by the Super Flare again. Because the number of case studies analyzed is not enough. And it is necessary to study that What exactly is causing the superflare to occur on sun-like stars?
