Drawing - double star Gamma Andromeda - 150 x 150
 
 

Drawing - double star Pi Aquilae - 150 x 150

The moon, the planets, and the STARS are visible in color to the human eye. Deep space objects like nebulae and galaxies are not. That's because the moon, planets and stars are bright, whereas deep space objects like nebulae are dim, and the human eye cannot distinguish color in dim light. 

The moon and planets shine at us with reflected light. The stars supply their own, and they openly display their genuine personalities; their true colors; the stuff they're made of. The many colors we see of stars are validations of their true identities. And some of them display those identities with striking boldness! For instance, aging carbon stars glow red; hot young stars are white or bluish; aging giants appear orange and red-orange. There are other colors such as violet, purple, pink, and even green and blue-green (although the color green in stars is an illusion). Our own Sun is yellow.

The page you see here is the result of an ongoing effort to render a Double Star Catalog of unsurpassed quality. Wherever possible, the colors shown represent an accurate rendition of actual observations. 

At left are just two examples of the many attractive double stars posted on our Double Star Drawings page.

In our Drawings you may notice that some doubles are presented in more than one color combination. That's because on subsequent nights they appeared differently, due in large part to changes in local atmospheric conditions. In these cases we offer more than one rendition, as we're not sure which one is most accurate. Keep in mind that we make no claim as accomplished artists or cartographers.


Note: Our website is rendered with Netscape Composer. This utility, though very adequate, is not without its crappy little bugs. One of these annoying bugs is its insistance on deleting spaces after a colored font. You may notice that we had to include invisible periods after each color indicator so the text would not "bunch-up". We tried to catch them all. Every now and then we find more and we fix them.
