Superflares Ejected By The Sun Might Ruin The Earth In The Future

Saturn-like planet orbiting not 1 but 2 stars

Astronomers have been looking at the edges of the Milky Way galaxy have seen some very intense superflares originating from stars. Even Mature Stars Produce Superflares Superflares are incredible bursts of energy that are so powerful that it's visible hundreds of light-years away.

Superflares used to be thought of as a younger-star phenomenon, researchers said in a statement about the new study, but the new work suggests it can happen on the sun at rare intervals, of perhaps once every few thousand years.

They found that while superflares occur much more frequently in young stars-about every week or so-older stars do produce them, albeit, on average, every few thousand years.

In the new research paper, scientists using data from the Kepler space telescope surveyed stars like our own Sun to determine how common superflare events are.

If a superflare erupted from the sun, he said, Earth would likely sit in the path of a wave of high-energy radiation.

There is a likelihood that we on Earth could experience a disastrous superflare within the next 100 years or so, experts warn, as they underscored the vital importance of developing increased protection for electronic systems. In uncommon occasions, the light from far off stars appeared to get all of a sudden, and immediately, more splendid.

The list of superflares was narrowed down to 43 main-sequence stars that are similar to our Sun, and the researchers analysed the superflare energy and the star's properties to estimate how frequently similar stars emit these types of explosions. Astronomers assumed that this meant stars like the Sun have either grown out of their superflare phase or that such events were so rare that it wasn't really worth worrying about. Superflares from the sun aren't expected to be frequent, but it's still important to be cautious.

"But we didn't know if such large flares occur on the modern sun with very low frequency", he said. In any case, more established stars like the Sun - which is 4.6 billion years of age - likewise produce them occasionally.

To discover, specialists diverted to information from the European Space Agency's Gaia shuttle and from the Apache Point Observatory in New Mexico.

According to the study published in The Astrophysical Journal, these pyrotechnic events can occur on older suns and the sun is no exception, as it could release a massive superflare in the next 100 years. The researchers then subjected those rare events to a rigorous statistical analysis.

Notsu can't be sure when the next big solar light show is due to hit Earth.

Although it is not yet clear when this will exactly happen, Notsu believes that a superflare event might occur within the next century. "People may have seen a large aurora Now, its a much bigger problem because of our electronics", said Yuta Notsu.

Co-authors on the recent study include researchers from Kyoto University, the National Astronomical Observatory of Japan, University of Hyogo, University of Washington and Leiden University.
