The sun was photographed from the closest distance in human history. What does the sun look like?

The sun is a luminous sphere. People call the spherical part of the sun that emits strong light a "photosphere". Usually what everyone can see is that the sun is just the surface of this ball of light. On the surface of the photosphere, there often appear some black spots, which are vortices rolled up by the churning hot air on the surface of the photosphere. These vortices are called "spots". These sunspots vary in size, ranging from hundreds to a thousand meters in diameter to large ones reaching more than 100,000 kilometers in diameter, and dozens of Earths can fit inside them.

The sun is the center of the solar system and it is not stationary. In addition to orbiting the center of the Milky Way, the sun is also constantly spinning. Because the sun is a gas ball, its rotation does not rotate as a whole like the solid earth. The sun spins faster near the equator and slower as it gets closer to the poles. The rotation period of the sun's surface is different

The National Aeronautics and Space Administration (NASA) and the European Space Agency (European Space Agency) recently released the closest photos of the sun taken so far. Earth's closest star is only 48 million miles away. The photo was taken by Solar Orbiter, an international mission between the two agencies that accomplished the feat of approaching the Sun for the first time. Holly Gilbert, NASA scientist in charge of the mission, said in a statement: "These stunning images will help scientists piece together the Sun's atmosphere, which is important for understanding how the Sun drives nearby Earth." and space weather throughout the solar system is very important. "We did not expect such good results so early," said Daniel Muller, a project scientist at the European Space Agency. ?These images confirm that the Solar Orbiter is off to a good start. ?

The Solar Orbiter has helped researchers piece together various layers of the solar atmosphere and analyze the shape of the sun. The power of technology is truly great.
