It shows a "magnetic map of the Sun" that reveals the magnetic field strengths on the solar surface. The image in the middle of the first column, was taken by the Polarimetric and Helioseismic Imager (PHI) instrument on 18 June 2020.
The middle image shows projected, simultaneous solar images from EUI FSI (red) at Solar Orbiter's position during its first perihelion, the closest point in its orbit to the Sun, and the NASA Solar Dynamic Observatory mission (gray) in Earth orbit. So, EUI will be able to image the far side of the Sun as well as the solar poles. Solar Orbiter will travel around the Sun and out of the ecliptic plane, which loosely defines where the planets orbit. In this region, which is only about 100 km thick, the temperature increases by a factor of up to 100 to reach the one million degrees of the corona. The red images, taken at a slightly longer wavelength of 30 nanometres, show the Sun's transition region, which is an interface between the lower and upper layers of the solar atmosphere. The yellow images, taken at the extreme ultraviolet wavelength of 17 nanometres, show the Sun's outer atmosphere, the corona, which exists at a temperature of around one million degrees.
PHI SOLAR ORBITER FULL
The Extreme Ultraviolet Imager (EUI) Full Sun Imager (FSI) took the images in the top row and far right column across the week following, and contributed to the central image. The data collected during the flyby could help scientists unlock some of the biggest remaining solar mysteries, including why and how the temperature rises through the sun’s atmosphere.ĮSA's Solar Orbiter is revealing the many faces of the Sun. The spacecraft also carries high-resolution telescopes. Solar Orbiter’s 10 instruments will be running simultaneously, ready to measure the solar wind and keep an eye out for mini flares, called campfires, that researchers spied in the mission’s first images in 2020. You can track Solar Orbiter’s progress using a tool developed by ESA to follow the sun explorer’s journey.
PHI SOLAR ORBITER DOWNLOAD
The European Space Agency, which jointly manages the mission with NASA, will share the first images and data within a few weeks because it will take time to download and analyze everything gathered during the flyby, according to ESA.
This will take Solar Orbiter inside the orbit of Mercury, the closest planet to the sun. The spacecraft will come within 31 million miles (50 million kilometers) of the sun, less than one-third the distance between the star and Earth. The Solar Orbiter mission will make its closest flyby of the sun Saturday since launching in February 2020.
