RAINBOW IMAGE OF A DUSTY STAR
Resembling a rippling pool illuminated by underwater lights, the Egg
Nebula offers astronomers a special look at the normally invisible dust
shells swaddling an aging star. These dust layers, extending over
one-tenth of a light-year from the star, have an onionskin structure
that forms concentric rings around the star. A thicker dust belt,
running almost vertically through the image, blocks off light from the
central star. Twin beams of light radiate from the hidden star and
illuminate the pitch-black dust, like a flashlight shining in a smoky
room. The artificial "Easter-Egg" colors in this image are used to
dissect how the light reflects off the smoke-sized dust particles and
then heads toward Earth.
The Egg Nebula is located 3,000 light-years away in the constellation
Cygnus. This image was taken with Hubble's Advanced Camera for Surveys
in September and October 2002.
