Huge "solar presence" on the surface of the sun recorded by NASA

NASA has captured a huge solar prominence emerging from the sun's surface. The importance was recorded by the Solar Dynamics Observatory (SDO) satellite on October 25th. She traveled about 80,000 kilometers. The space agency noted that it was "about ten times the diameter of the Earth", which represents a little over 7,900 miles.

Solar preponderance is a largely unexplained phenomenon – scientists do not know exactly how and why they are formed. We see them bursting from the surface of the Sun in the crown, the aura of plasma surrounding our star. They are attached to the photosphere, which is the outer envelope of the sun and the part that emits light and heat.

"Our observatory satellite of solar dynamics has seen a solar prominence rise above the surface of the Sun, twist, and then lengthen and separate from the Sun," he said. NASA in a statement. "Prominences are relatively cold clouds of solar material [called plasma] which are attached above the surface of the Sun by magnetic forces. "

SDO images include an image of the Earth to show the vast scale of prominence.

The material in the loop is the plasma. Plasma is a hot gas composed of electrically charged hydrogen and helium that moves along the magnetic fields generated by the Sun. When a structure on the Sun becomes unstable, the plasma is released and bursts outward. Normally, a solar prominence will form during a day. However, there are cases where they persist and can last several months in the crown.

In case of breakage, a solar prominence can cause a coronal mass ejection during which the hot gas is expelled into the solar system.

Solar protuberances tend to spread over tens of thousands of kilometers in space. However, the biggest kicks can be much larger. According to Universe Today, an important reputation recorded in August 2012 was 500,000 miles long.

Even though humans have been studying the Sun for thousands of years, there are still many aspects that we do not understand. For example, we do not really know why the crown is so much hotter than the surface of the sun, or why sunspots are formed.

In an attempt to answer some of these questions, NASA has launched the Parker Solar Probe, a sensor that will "touch the sun". In October, the space agency confirmed that the probe had become the synthetic object closest to the sun, after having traveled 26.55 million dollars. miles from the solar surface. At the closest approach, the spacecraft will be only 3.8 million miles from the Sun.
