Happy 25 years observing the Sun, SOHO! 🌞 🎉
The joint @EuropeanSpaceAgency & NASA Solar and Heliospheric Observatory (SOHO) mission launched on Dec. 2, 1995. Over the years, its set of groundbreaking instruments became a source for numerous scientific findings, an inspiration for follow-on missions, and an outlet for citizen scientists. It's become the longest-running Sun-surveying spacecraft.
SOHO was meant to provide a comprehensive look at the flow of energy and material from the Sun toward Earth. Over the last quarter of a century, researchers learned they could, in fact, begin to monitor our Sun in real time, studying and attempting to predict the space weather it sent our way. Beyond the day-to-day monitoring of space weather, SOHO has been able to provide insight about our dynamic Sun on longer timescales as well.
SOHO's coronagraphs allow researchers to see, in breathtaking detail, giant eruptions of solar material and magnetic fields known as coronal mass ejections (CMEs). This video, using images taken on July 22-24, 2012, shows SOHO's coronagraph view of a massive CME that erupted off the Sun's right side and zoomed out into space.
