Solar probe Solar Orbiter sent to Earth all science data gathered during the first rendezvous with the star, held in June 2020. Preliminary analysis has allowed astronomers to find numerous microspace in the Sun, which can help in solving the problem of abnormal heating of the corona, reported on the ESA website.
Solar Orbiter was launched into space on 10 February 2020. For nine years, he will explore coronal mass ejections, formation of prominences, to determine the magnetic field in active regions of the Equatorial belt of the Sun to study the corona of the star and the acceleration mechanisms of the solar wind, and also for the first time to observe the polar regions of the Sun and get them direct the full image. To perform scientific tasks, the station is equipped with a set of ten scientific instruments, most of which is covered under layered sun shield.
June 15, 2020, the probe successfully passed its first perihelion, being at a minimum distance of 77 million kilometers from the Sun. Image of stars taken by the instrument EUI extreme ultraviolet wavelength range, has allowed scientists to identify numerous small flares, which received the unofficial designation of “fires” (campfires). They are several million times less intense than usual solar flare, was observed around the disk of the Sun. Astronomers have yet to understand the mechanisms of generation of such outbreaks, however, the hypothesis that “fires” can play a role in the supply of energy in the solar corona, providing anomalous heating.
