NASA Telescope Takes its 100 Millionth Picture of the Sun, and Its Gorgeous
On Monday, Jan. 19, 2015 a sensor on NASA’s Solar Dynamics Observatory snapped its 100 millionth image of the sun.
“The instrument is the Atmospheric Imaging Assembly, or AIA, which uses four telescopes working parallel to gather eight images of the sun – cycling through 10 different wavelengths — every 12 seconds,” NASA said in a press release.
Since its launch in February 2010, the Solar Dynamics Observatory has been used “to help scientists better understand how the roiling corona gets to temperatures some 1,000 times hotter than the sun’s surface, what causes giant eruptions such as solar flares, and why the sun’s magnetic fields are constantly on the move,” NASA says.
