* Ultraviolet (UV): SOHO's instruments like SUMER and CDS observe the Sun in various UV wavelengths, providing information about the Sun's upper atmosphere (corona) and its temperature and composition.
* Extreme Ultraviolet (EUV): SOHO's EIT instrument captures images of the Sun in EUV wavelengths, revealing the hot plasma in the corona and solar flares.
* Visible Light: SOHO's LASCO instruments observe the Sun in visible light to study the corona, coronal mass ejections (CMEs), and other solar phenomena.
* X-rays: SOHO's X-ray instruments like XRT monitor solar flares and other energetic events that emit X-rays.
SOHO also carries instruments to detect:
* Solar Wind Particles: The CELIAS instrument measures the composition and properties of the solar wind, the stream of charged particles flowing from the Sun.
* Radio Waves: The WAVES instrument detects radio emissions from the Sun, which provide insights into solar flares and other energetic events.
Therefore, SOHO's diverse array of instruments allows it to observe the Sun across a broad range of the electromagnetic spectrum, providing valuable information about the Sun's activity and its influence on the solar system.
