The total solar eclipse of April 8 is just 4 days away. The corona, or sun’s outermost atmosphere, will be the star of the show when the moon covers the sun completely. You can't see the corona with your own eyes at any other time. So the wispy, white streamers - surrounding the black moon - will be a sight you'll never forget! Learn about it here.
