6 FAQs about [Solar flare power]
What is a solar flare?
A solar flare is an intense burst of radiation, or light, on the Sun. These flashes span the electromagnetic spectrum — including X-rays, gamma rays, radio waves, and ultraviolet and visible light. Solar flares are the most powerful explosions in the solar system — the biggest ones can have as much energy as a billion hydrogen bombs.
How long do solar flares last?
Solar flares can last anywhere from minutes to hours, and they release radiation across the entire electromagnetic spectrum—meaning they give off X-rays, ultraviolet light, and radio waves. You can think of it like the Sun suddenly turning on a super powerful flashlight that floods the space around it with energy.
How does a solar flare impact the Earth?
Solar flares are electromagnetic wave bursts, which can disrupt radio communications on dayside Earth (Fig. 3.1). The flare impact starts instantaneously as it is electromagnetic radiation. Note also that it takes ∼8 minutes for traveling from the Sun to the Earth by the speed of light (Fig. 2.1).
What is the most powerful type of solar flare?
According to NASA, X-class flares are the most powerful solar flares. There are five classes of solar flares, according to NOAA. Their designation depends on the intensity of X-rays emitted. Each class letter represents a 10-fold increase in energy output, similar to the Richter scale that measures the strength of earthquakes.
What causes solar flares?
Solar flares are caused by the sudden release of magnetic energy that builds up in the solar atmosphere. These outbursts are intrinsically linked to the solar cycle, an approximately 11-year cycle of solar activity driven by the sun's magnetic field.
What does a solar flare look like?
NASA’s Solar Dynamics Observatory captured this image of a solar flare — seen as the bright flash on the left side of the Sun — on March 28. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in red. Credit: NASA/SDO Solar flares are powerful bursts of energy.
