Images sent back by the European Space Agency's probe show pillar-like structures made of plasma, as well as explosions and rain falling on the surface of the relatively cooler material, he wrote. Watchman.
Scientists say observations of the complex dynamics of the Sun's surface could help answer the question of why the Sun's atmosphere is hotter than its surface, a long-standing paradox in solar physics.
The brightest regions have a temperature of about 1 million degrees Celsius, while cold material below 10,000 degrees Celsius appears darker. The image was taken by the Extreme Ultraviolet Imager (EUI) instrument on September 27, 2023, when the spacecraft was about a third of the distance from Earth to the Sun.
The video shows the delicate lace-like patterns that stretch across the sun, called coronal mosses. These structures appear at the base of large coronal magnetic field loops. On the horizon, peaks of gas, called spicules, extend from the heliosphere to an altitude of about 10,000 km.
In the center of the field of view, you can see a small explosion, as the cold material mostly rises and then recedes. Although small in size compared to major events, this explosion is still larger than the diameter of the Earth.
On registration Coronal rain is also visible, which with its temperature below 10,000 degrees Celsius appears dark against the bright background of the large coronal loops at about a million degrees Celsius. Rain consists of dense clumps of plasma that fall toward the sun under the influence of gravity.
Launched in 2020, the $1.3 billion mission will begin observing the Sun's previously uncharted north and south poles next year.
