SOHO’s coronagraph — one of 12 instruments — was a gamechanger. Coronagraphs use a disk to block out the Sun’s bright face and reveal the faint outer atmosphere, the corona, to see how it changes and track giant eruptions of solar material called coronal mass ejections.pic.twitter.com/KUz06rbzPM

Coronal mass ejections can impact robotic spacecraft in their path, or — when intense and aimed at Earth — threaten astronauts on spacewalks and even disrupt power grids on the ground. Today, SOHO’s coronagraph images are the backbone of space weather models.

Beyond day-to-day monitoring, SOHO has also provided insight into our Sun over a full magnetic cycle, when the Sun’s magnetic poles flip from north to south and back again, a process that takes 22 years.pic.twitter.com/9SCKilqYFb

SOHO’s trove of data has led to revolutions in solar science: from revelations about the behavior of the solar core to new insight into space weather events that explode from the Sun and travel throughout the solar system.

The legacy of SOHO’s instruments — such as the extreme ultraviolet imager, the first of its kind to fly in orbit — also paved the way for the next generation of NASA solar satellites, like the Solar Dynamics Observatory and STEREO.pic.twitter.com/bDT9C4yb0a

SOHO has also become the greatest comet finder of all time, thanks to its coronagraph instrument. The mission’s data has revealed more than 4,000 comets to date, many of which were found by citizen scientists. https://go.nasa.gov/33x53Qb pic.twitter.com/ab3eYWWpfI

oh! yes, thanks to soho we can see and analyze the sun obtaining beautiful images of large CME's.

Mango tree. The number of mangos. Albert Einstien is one of the mangoes. Just I am the second mango. how? E = mc^2 is correct. But E is free. Because perpetual motion machine is researched out. E can be produced without loss of mass. Now you be third mengo. Go to my profile.
