Sun Could Still Unleash Dangerous Superflares: What Would Happen To Earth Then?


While hunting for planets around distant stars using the Kepler Space Telescope, however, NASA scientists noticed that far-flung stars can on rare occasions release bursts of energy that are similar to flares, but up to thousands of times more intense. A new study suggests that older stars like the sun can produce superflares - huge bursts of energy visible across hundreds of light-years.

"When our Sun was young, it was very active because it rotated very fast and probably generated more powerful flares", said Notsu in Boulder.

It was previously thought that older stars like our Sun - a healthy 4.6 billion years old - didn't really have the power to eject superflares, however a group of eggheads led by the University of Colorado Boulder in the USA this week showed this isn't the case.

It was long thought that these superflares only took place on young and active stars and that our sun-which is much older-would not be capable of producing them.

It is already known that solar flares can disrupt essential electrical equipment, including power lines, electronic devices, and satellites.

"Our study shows that superflares are rare events", Notsu explains.

To investigate, Dr Notsu and his colleagues from Japan, the United States and the Netherlands studied superflares detected from 43 Sun-like stars using data from the European Space Agency's Gaia spacecraft and New Mexico's Apache Point Observatory. However, a team of astronomers in the United States has shockingly announced our own Sun could unleash one of these flares before the end of next century. Be that as it may, what the Kepler information was appearing at being a lot greater, on the request of hundreds to thousands of times more dominant than the biggest flare at any point recorded with present-day instruments on Earth.

Initially, scientists believed that superflares were only limited to be an occurrence in younger stars.

"Be that as it may, we didn't have the foggiest idea if such enormous flares happen on the cutting edge sun with low recurrence", he said.

Data from the Gaia spacecraft and the Apache Point Observatory also played an important role in the research.

Notsu clarified that ordinary measured flares are basic on the Sun.

Stars are unpredictable. They occasionally and randomly let out belches of plasma, particles, and radiation, in the form of solar flares or coronal mass ejections. The researchers then subjected those rare events to a rigorous statistical analysis. In any case, more established stars like the Sun - which is 4.6 billion years of age - likewise produce them occasionally. But he said that it's a matter of when, not if.

"If a superflare occurred 1,000 years ago, it was probably no big problem", said Notsu. "People may have seen a large aurora", Notsu said in a published statement, referencing phenomena like the Northern Lights.

According to the researcher, citizens, private companies and government agencies should begin investing on practical solutions aimed at protecting electronics from radiation. "Now, it's a much bigger problem because of our electronics".
