Surface of the Sun

Sun is a star that lights our solar system and is a source of making life’s existence possible. From Earth, we see sun as a yellow spot in the sky. We connote it with many happy and cheerful and hopeful terms for our life. In reality, sun surface is a blazing, extremely hot ball of molten lava and fire that glares and erupts molten fire and rock into space. 

Scientists at NASA have discovered that at any moment about 10 million jets of blazing fire erupts into space from the surface of the sun. The eruptions range up to 6000 miles length and eruptions are 60 miles per second. Scientists call these erupted flares, Spicules. A detailed computer simulation has helped scientists find out the formation of these spicules that cover the surface of the sun.

Sun SurfaceSpicules are the long filaments or strands of solar material. They are highly dynamic and have a very short life for they emerge from the ashes again and again like a phoenix. NASA has used the Swedish 1-meter solar telescope and IRIS to study the origin of these spicules.

Charged and neutral particles interact with the magnetic field to produce these spicules. This interaction causes strands of magnetic field to form that extend to heights causes the solar material to travel across it into lengths of space. The strong magnetic field of the sun might be helpful in spreading a constant heat across the entire solar system from the sun.

By understanding about the spicules, we can infer how energy from the sun moves towards the planets orbiting it. In an article by NASA, Scientists Uncover Origins of the Sun’s Swirling Spicules, it is said that, “in cooler regions of the sun surface, such as the interface region, not all gas particles are electrically charged. Some particles are neutral, and neutral particles aren’t subject to magnetic fields like charged particles are.” Hence they knew that in order to understand these spicules they needed to keep the neutral particles in mind as well.
NASA devised a model based on the basic knowledge of plasma and how it moves in the atmosphere of the sun. Since the sun’s temperature is very high and the constant boiling cause intense magnetic field to form around the sun. Also in the article it is said, “When boiling carries those up to the sun surface and farther into the sun’s lower atmosphere, magnetic field lines rapidly snap back into place to resolve the tension, expelling plasma and energy. Out of this violence, a spicule is born.” (Scientists Uncover Origins of the Sun’s Swirling Spicules, 2017)

This discovery reveals the source of sun’s constant energy and the reason to its extensions throughout the solar system. Spicules give energy to the sun’s atmosphere by constantly forcing plasma out into space. Which keeps energy waves throughout the surface of the sun.
