Solar flares can impact Earth, infra, astronauts, other living organisms! NASA explains

tech.hindustantimes.com:

Solar flares and solar eruptions keep on happening. Though the intensity of the flares vary, they can cause problems on Earth, that is, solar flares can prove to be dangerous for living organisms. Meanwhile, if you are not yet aware of solar flares, it can be known that a solar flare is an intense burst of radiation on the Sun. "Flares are our solar system's most powerful explosive events – the most powerful flares have the energy equivalent of a billion hydrogen bombs, enough energy to power the whole world for 20,000 years. Light only takes about 8 minutes to travel from the Sun to Earth, so that's how long it would take the energy from a flare to reach our planet," NASA said in a blog post.

NASA has been very active in informing about the solar flares that are happening and their impact on Earth. But what needs to be noted is that solar flares only affect Earth when they occur on the side of the Sun facing Earth or else they will pass elsewhere into space. Solar flares are rated in different classes based on their strength, or energy output, and the effect a flare will have on Earth depends on what class it is (B, C, M, and X classes, with X being the most intense), NASA informed.

Solar flares can last from minutes to hours. Sometimes the same active region on the Sun can give rise to several flares in succession, erupting over the course of days or even weeks. Here is how it can impact Earth and living beings.

Flares are not directly harmful to humans on ground as Earth's atmosphere absorbs most of the Sun's intense radiation. However, the radiation from a flare can be harmful to astronauts outside of Earth's atmosphere,
