Random Note

When the freaky green star you are looking at through the apple tree suddenly darts left, you may be observing a lightening bug.

Sadly, there are no stars we preceive as green.


  1. Sad indeed, being that green is the best of all colors. Are there other objects out there that appear green?

  2. Some of the stars in your banner picture sure look green! 😉

    I’ve been listening to Astronomy Cast for awhile now, but just stumbled on your blog today…I live in O’Fallon, IL, not far from SIUE… It’s nice to know there’s a fellow astronomy geek girl nearby!

  3. According to George on the BOUT forum our sun outputs most in green… not sure how for he got though we lost touch about 5 months ago 🙁

  4. It’s all a mater of perception! Stars that have a temperature between 5000 and 6000 K will have a peak color between yellow-green, and green blue (with Crayola green in the mid-5000s). Our eyes struggle with this color in low light conditions, however, so we don’t generally precieve stars to be green when using our eyes. Cameras can integrate the light over time to build up pretty pictures that include green stars and galaxies. From the Earth’s surface, the universe is best seen in technicolor using a camera.
