Rare 'superflares' from Sun could disrupt Earth's communications

Updated: few hours ago

Washington, Jun 12 (PTI) Superflares erupted from the Sun could disrupt electronics across the Earth, causing widespread black outs and shorting out communication satellites in orbit, scientists warn.

Astronomers probing the edges of the Milky Way have in recent years observed superflares -- huge bursts of energy from stars that can be seen from hundreds of light years away.

Until recently, researchers assumed that such explosions occurred mostly on stars that, unlike Earth's, were young and active.

Scientists from University of Colorado (CU) Boulder in the US have found that superflares can occur on older, quieter stars like our own -- albeit more rarely, or about once every few thousand years.
