Green and Red Lines

  • Wrarthis by Wrarthis

    Hi all, I am wonder if the green and red lines are human made or natural?

    Welcome to Galaxy Zoo, Wrarthis!

    They're satellite trails (or, possibly, an aircraft or meteor). This one is unusual in that both red and green trails are recorded (green is much more common; red and blue less so).

    Happy hunting! 😃
