Q. Solar and Heliospheric Observatory (SOHO), recently seen in the news, is a project of international collaboration between which two space agencies?
Answer:
ESA and NASA
Notes: A citizen scientist recently discovered the 5,000th comet using Solar and Heliospheric Observatory (SOHO) data. SOHO, a collaboration between ESA and NASA, launched in 1995 to study the Sun from the first Lagrangian Point. Equipped with 12 scientific instruments, it continuously observes the solar atmosphere, helioseismology, and solar wind. Despite its mission ending in 1998, SOHO persists, providing invaluable insights into the Sun's dynamics and discovering numerous comets, making it the longest-lasting Sun-watching satellite.
