A solar flare is a sudden and massive explosion on the Sun that happens when energy stored in 'twisted' magnetic fields is suddenly released.
NASA in a report said that flares are our solar system's largest explosive events.
The solar flares are seen as bright areas on the Sun and they can last from minutes to hours.
They produce sudden and intense light flashes, sending high-energy particles and a burst of ultraviolet rays into space. Those articles can reach the Earth in a few hours or in days.
The particles create a magnetic storm in the Earth's atmosphere that can last for days.
The flares can cause radiation storms in the upper atmosphere, radio blackouts around the world, and mobile phone outages.
Some people have reported feeling sick or having headaches due to solar flares, but there's no research to prove it.
