2024年11月2日 · The ESA-sponsored Solar and Heliospheric Observatory (SOHO) carries 12 scientific instruments to study the solar atmosphere, helioseismology, and the solar wind. Information from the mission has allowed scientists to learn more about the Sun’s internal structure and dynamics, the chromosphere, the corona, and solar particles.

2023年12月2日 · The Solar and Heliospheric Observatory (SOHO) is stationed 1.5 million kilometres away from Earth. There, it constantly watches the Sun, returning spectacular pictures and data of the storms that rage across its surface.

SOHO is on the sunward side of the Earth, where it enjoys an uninterrupted view of the Sun. Every day it sends thrilling images from which research scientists learn about the Sun's nature and behaviour. And experts around the world use SOHO images and data to help them predict bad space weather affecting our own planet.

2011年12月2日 · SOHO (SOlar Heliospheric Observatory) is a space-based observatory, viewing and investigating the Sun from its deep core, through its outer atmosphere - the corona - and the domain of the solar wind, out to a distance ten times beyond the Earth's orbit.

Stationed 1.5 million kilometres away from Earth, SOHO constantly watches the Sun, returning spectacular pictures and data of the storms that rage across its surface. SOHO's studies range from the Sun's hot interior, through its visible surface and stormy atmosphere, and out to distant regions where solar wind battles with a breeze of atoms ...
