Almost two years and about four months after its launch on June 15, 2020, made his first visit ” near “ of our Le Soleil est l’étoile la plus proche de la Terre, dont elle est distante d’environ 150 millions de kilomètres. Le Soleil est situé à 8,5 kparsecs du centre de la Voie lactée. Dans la classification des étoiles, le soleil est une étoile de type G2.

The probe (ESA, ) then passed 77 million kilometers from our . About half the Earth-Sun distance. A great opportunity especially for researchers to test the ten instruments on board the machine. But the goal has not yet been achieved.
Since then, Solar Orbiter has benefited from several operations oftrusting our Earth and to finally, this Saturday, March 26, 2022, bring our star closer to less than a third of the . Or about 30 million miles from its bubbling surface alone. The probe thus penetrated the . And all ten of his instruments worked perfectly, collecting data and images of our Sun as the I’ve never seen it before.
Over the next several years, Solar Orbiter will make several passes near our star. Certainly sending valuable information to researchers, especially as the probe will also increasingly be aimed at . Regions that have rarely been observed.
The Sun in Extraordinary Resolution
Waiting for these unpublished photos to be published and to reveal a little more of the secrets of our star, researchers working on the Solar Orbiter mission are already sharing an image of a amazing. about 83 million . A resolution ten times better than that of our 4K screens, simply the best image ever obtained of the corona and the entire disk of our Sun.
The image was taken on March 7. Using theExtreme image generator (EUI), when Solar Orbiter was about half the distance between Earth and the Sun. The image, or rather, the images. Because the spatial resolution of EUI is such that at 75 million kilometers, 25 images are needed to cover the entire surface of our Sun. At a rate of about ten minutes per shot, the probe will have taken no less than four hours to immortalize our star.
Since it is in the extreme ultraviolet range that EUI observes our Sun, at a of 17 astronomers will be able to obtain information from high of our star. An environment in which rises to about a million .
Another set of awesome images.
The instrument called Spectral images of the coronal environment (SPICE) also returned exceptional images. The first of its kind in 50 years. And in fact, by far the best.
The instrument is designed to pierce the layers of the sun’s atmosphere, from the corona inward to the chromosphere, by analyzing wavelengths of La lumière blanche
