The amazing photos of NASA allow you to watch the solar explosion in real time.

The sun is an invisible electromagnetic explosion ball. This amazing ultraviolet image taken by NASA Solar Dynamics Observatory simulates the actual appearance of those rotating electric field lines. NASA Solar Dynamics Observatory, don't panic, but the sun keeps exploding. When the intense nuclear fusion reaction provides energy for the melting plasma tower, the core of the sun at 27 million degrees Fahrenheit (15 million degrees Celsius), the crackling radiation and electromagnetic energy fluctuate constantly on the hot surface of the star, forming the entanglement of light and heat.

It's so cool that the human eye can hardly see it. Fortunately, researchers at NASA's Solar Dynamics Observatory use computer models to capture snapshots of this invisible solar energy every day. Yesterday (August 16), they shared one of the snapshots, which you can see above. [Solar Storm: Incredible Photos of Solar Flares]

In the computer-enhanced ultraviolet photo, we can see a model of solar magnetic field line, which spins out of the star surface in the way of 20 18+65438 August. Each white line represents a powerful electromagnetic explosion, which is caused by the high-energy interaction between overheated and pressurized particles, which constitute the magnetic field of the sun and the plasma rotating around the surface of the star.

As shown in the figure, one part of these energy flows is injected into space, generating solar wind and other space weather, and the other part rises from the surface of the sun, rotates, and then falls in a closed cycle. These magnetic energy rings will further stir the charged particles on the surface of the sun, leading to an increasingly large explosion of solar weather, including solar flares and large radiation belts called coronal mass ejections.

It seems that many things may happen, but historically, the sun is actually experiencing a slow season. Scientists don't know the exact reason, but the solar magnetic field seems to follow a fairly reliable activity cycle of 1 1 year. During this 1 1 year, these solar cycles gradually become larger and more complex, and then reset to a relatively stable state. At the end of each cycle, the more solar radiation, the more frequent sunspots, and powerful solar storms are more likely to shine from the surface of the sun and deep in the sky. Once the magnetic field reaches the maximum active point-or the maximum value of the sun-the magnetic pole of the star turns over, and a new period of relative inactivity begins again. (This new beginning, you can infer, is called "solar minimum period") "KDSP" and "KDSP" are the last solar maximum period in April of 20 14. According to NASA data, the standard of solar history is quite weak. One of the biggest solar storms in history, such as the so-called Carrington event, occurred at 1859 near the solar maximum. When a huge solar wave hits the earth, the wires are short-circuited, resulting in an explosion and fire. Beautiful auroras (usually only seen in the polar regions) twinkle in the sky as far away as Cuba and Hawaii. Fortunately, 20 14 doesn't have that much to do.
