1 00:00:00,700 --> 00:00:02,669 What does the Sun look like? 2 00:00:02,669 --> 00:00:05,138 Well, it depends on how you view it! 3 00:00:05,138 --> 00:00:07,507 Since its launch in February 2010, 4 00:00:07,507 --> 00:00:11,344 NASA's Solar Dynamics Observatory, or SDO, has produced 5 00:00:11,344 --> 00:00:14,781 some of the most iconic images of our star — including this one. 6 00:00:16,649 --> 00:00:18,118 In this visualization, 7 00:00:18,118 --> 00:00:20,520 each “slice” represents a different wavelength 8 00:00:20,520 --> 00:00:23,990 of ultraviolet light that SDO uses to view the Sun. 9 00:00:24,591 --> 00:00:27,460 Each wavelength highlights a specific temperature range 10 00:00:27,460 --> 00:00:30,463 that helps scientists study different solar activity. 11 00:00:30,930 --> 00:00:34,501 This wavelength reveals features at around 1.8 million 12 00:00:34,501 --> 00:00:36,770 degrees Fahrenheit, like solar flares, 13 00:00:37,771 --> 00:00:39,773 while this one emphasizes features 14 00:00:39,773 --> 00:00:43,076 at 1 million degrees Fahrenheit, like coronal loops. 15 00:00:43,910 --> 00:00:48,581 Scientists use these different SDO views to paint a full picture of our constantly 16 00:00:48,581 --> 00:00:52,252 changing star and its effects on Earth and technology in space.
