Giant tornadoes form on the sun. “We finally know what makes them” [FILM] – NeeWS

Scientists from the University of Warwick and the Italian Space Agency have taken a closer look at the most spectacular phenomena we have ever seen on the surface of our daily star. It is a tornado made of plasma heated to almost 3 million degrees Celsius and about a few times larger than our planet. These structures are terrifying with their dynamics.

Numerical simulations suggest that the rotating structures observed in the solar chromosphere are markers of magnetic structures that, through centrifugal forces, force the solar plasma to move up along the magnetic field lines“- said Mariarita Murabito, researcher at Rome-INAF.

Astronomers had several ideas on the essence of their formation and functioning, but so far they have no evidence. Now it has changed. Finally, we know what creates them, and with this knowledge, we will be able to better prepare the cosmic weather, which has a significant impact on our expansion to the Moon or Mars and the construction of the first colonies there. The sun can thwart our plans for research missions to alien worlds. It was like that in the past. Now it is to change.

It turns out that these giant tornadoes are formed as a result of powerful and rapidly changing magnetic field lines. They lift plasma heated to millions of degrees Celsius and tear it to all sides, creating vortex-like swirls. They can be thousands of kilometers long. We can observe them in the chromosphere, i.e. the atmospheric layer, whose name comes from the red color observed during total solar eclipses.

Astronomers are pleased that solar research is entering a new era with the next generation of telescopes, such as the 4-meter solar telescope Daniel K. Inouye in Hawaii. Two months ago, astronomers working at the Solar Telescope Daniela K. Inouye, presented the most accurate image of the surface of the Sun in history. We can see giant convection cells on it. Each of them has the size of Poland, and the smallest diameter is not less than 35 kilometers. Bright centers are places where solar material rises up, meanwhile the dark stripes surrounding them are places where the plasma falls, cools and sinks.
