The Record Breaking Filament on the Sun

On February 9, 2015, NASA’s Solar Dynamics Observatory (SDO) captured one of the longest filaments ever recorded. It stood around for almost a week over my birthday week (the 16th of February) and was very apparent for days after that first sighting. The enormous filament extended across the face of the Sun at a distance longer than the Sun’s radius — over 533,000 miles, which is the length of 67 Earth’s lined up by the way.  A filament is simply hot gas held tightly above by the Sun’s magnetic field. The featured images show the filament in a few different lens views. NASA’s SDO celebrated 5 years of amazing footage capture this past year and we look forward to many more years of amazing footage to come!
