ESAのソーラーオービター宇宙船から新たに分析されたデータは、太陽ディスク全体の高解像度画像を初めて提供した。
Newly analyzed data from ESA’s Solar Orbiter spacecraft offer the first high-resolution view of the entire solar disk
The entire solar disc in unprecedented detail – this is shown by images of the visible surface of the sun, which researchers at the Max Planck Institute for Solar System Research have now created from 25 individual images taken by the Esa space probe Solar Orbiter. During the observations in March 2023, the satellite was only half as far away from the sun as Earth. Here, the solar disk was already too large to fit into a single photo. If you zoom in on the images from the various instruments that have now been published, you can see where the Sun is displaying its temper. The surface resembles a boiling water surface. Here, plasma is rising from the Sun’s interior. Dark sunspots are also spots of particularly strong magnetic fields. And wide magnetic field loops, larger than the Earth, form a racetrack for solar plasma, which whizzes along there at over 100,000 kilometers per hour.
No body in our Solar System is as dynamic and complex as the Sun. In order to understand as many of its caprices as possible, the ESA’s Solar Orbiter spacecraft set off in February 2020 with a total of six measuring instruments in the direction of our home star, in order to look under and into the various layers of our star. The Max Planck Institute for Solar System Research sent hardware for four of the instruments on the journey to the fireball. For example, EUI captures the Sun’s particularly short-wave ultraviolet radiation which originates primarily in its hot outer atmosphere, the solar corona. The double telescope PHI focuses on the visible surface below, the photosphere. The light emitted from there also contains information about the strength of the Sun’s magnetic field and the velocity of the solar plasma. The images published today are derived from EUI and PHI data from March 22, 2023.
