scientists revealed the secret of dark ovals on Jupiter – TSN, news 1+1 — Science and IT
You can see them only in ultraviolet light.
Researchers have discovered that magnetic tornadoes on Jupiter, which arise as a result of the interaction of magnetic field lines, lead to the formation of giant anticyclones. These structures absorb ultraviolet light and have dimensions commensurate with the Earth.
Nature Astronomy writes about it.
Anticyclones appear as dark ovals, visible only in ultraviolet light, and are formed from thick clouds in the planet's stratosphere. The mechanism of their formation remained a mystery until recently.
The reason for the formation of dark circles is magnetic vortices. They are formed by friction between the magnetic field lines in Jupiter's ionosphere and the plasma torus created by the volcanic activity of Io's moon. These eddies spread into the stratosphere, forming a dense fog that absorbs…
