Are sun flares dangerous?
Solar flares and CMEs pose no direct threat to humans—Earth’s atmosphere protects us from the radiation of space weather.
(If an astronaut out in space is bombarded with the high-energy particles from a CME, he or she could be seriously injured or killed..
What if the 2012 solar flare hit Earth?
Analysts believe that a direct hit by an extreme CME such as the one that missed Earth in July 2012 could cause widespread power blackouts, disabling everything that plugs into a wall socket. Most people wouldn’t even be able to flush their toilet because urban water supplies largely rely on electric pumps.
What is the biggest solar flare in history?
April 2, 2001At 4:51 p.m. EDT, on Monday, April 2, 2001, the sun unleashed the biggest solar flare ever recorded, as observed by the Solar and Heliospheric Observatory (SOHO) satellite. The flare was definitely more powerful than the famous solar flare on March 6, 1989, which was related to the disruption of power grids in Canada.
How many hydrogen bombs worth of energy is created by the sun every second?
To put this into a crazy context, every second the sun produces the same energy as about a trillion 1 megaton bombs! In one second, our sun produces enough energy for almost 500,000 years of the current needs of our so-called civilization.
What happens if a sun flare hits Earth?
The most powerful solar storms send coronal mass ejections (CMEs), containing charged particles, into space. If Earth happens to be in the path of a CME, the charged particles can slam into our atmosphere, disrupt satellites in orbit and even cause them to fail, and bathe high-flying airplanes with radiation.
Can a solar flare destroy Earth like in knowing?
Most importantly, however, even the biggest solar flares are not powerful enough to physically destroy Earth. This is not to say that space weather can’t affect our planet. The explosive heat of a solar flare can’t make it all the way to our globe, but electromagnetic radiation and energetic particles certainly can.
