Stanford SOLAR Center -- Ask A Solar Physicist FAQs - Answer

Solar flares release a lot of radiation into space. If a solar flare is very intense, the radiation it releases can interfere with our radio communications here on Earth. A loop of solar material, a coronal mass ejection CME , can also be seen rising up off the right limb of the Sun.

NEW: What’ll happen when superflare hits Earth

Solar flares are sometimes accompanied by a coronal mass ejection CME for short. CMEs are huge bubbles of radiation and particles from the Sun.

When charged particles from a CME reach areas near Earth, they can trigger intense lights in the sky, called auroras. When particularly strong, a CME can also interfere in power utility grids, which at their worst can cause electricity shortages and power outages. Solar flares and CMEs are the most powerful explosions in our solar system.

Round-up: sunspots and solar flares

The Short Answer:. Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots. More about the Sun!

    A tech-destroying solar flare could hit Earth within 100 years

    Solar flares fling tremendous amounts of energy into space, including high-energy particles protons, electrons, and atomic nuclei and electromagnetic radiation ranging from gamma rays and X-rays to radio waves. Particles travel more slowly, taking anywhere from about 30 minutes for higher energy particles to several days to reach the earth.

    When electromagnetic radiation and particles from flares do reach the earth, they can cause space weather effects , including disruptions in communications. Look for current solar flares using live data. Solar Flares Solar flares are short-term outbursts on the sun, caused by the sudden release of energy stored in twisted magnetic fields in the solar atmosphere.
