SOHO is the longest-lived heliophysics mission still operating and has provided a nearly continuous record of solar and heliospheric phenomena over a full 22-year magnetic cycle (two 11-year sunspot cycles). SOHO's findings have been documented in over 5,000 papers in the peer reviewed literature, authored by more than 4,000 scientists worldwide.

Besides watching the Sun, SOHO has become the most prolific discoverer of comets in astronomical history: as of late 2017, more than 3,400 comets have been found by SOHO, most of them by amateurs accessing SOHO real-time data via the Internet.
