X-ray data recorded by Chandra appears here in blue; infrared light recorded by Spitzer appears in red; Hubble's observations of hydrogen appear in orange, and the bluest visible light appears in yellow-green.
Comet ISON floats against a seemingly infinite backdrop of numerous galaxies and a handful of foreground stars. The icy visitor, with its long gossamer tail, appears to be swimming like a tadpole through a deep pond of celestial wonders. In reality, the comet is much, much closer. The nearest star to the Sun is over 60,000 times farther away, and the nearest large galaxy to the Milky Way is over thirty billion times more distant.
Scientists are now able to see a picture of the universe that measures up to a distance of 93 billion light years. Light from the early universe is just now reaching to earth so we are able to see a bigger picture.
