A digitized 35mm astrophoto of Comet Hale-Bopp (C/1995 O1) taken a few days after its perihelion passage on April 1, 1997. The image shows the comet's distinct dust and ion tails against a backdrop of stars. The photo was hand-guided for 10 minutes using a telephoto lens piggybacked on a small telescope.

Negative image of Comet Hale-Bopp in the constellation Pictor. Taken with a 1-meter telescope, this long-exposure shot reveals the comet's substantial tail and a unique anti-tail pointing towards the sun, composed of large dust grains unaffected by solar wind. The comet, last visible in 1997, is currently 400 million miles from the sun.

Shadow Of A Comet

False-color image from SOHO's SWAN instrument showing the shadow of Comet Hale-Bopp cast against the sun's ultraviolet light scattered by interstellar hydrogen. The dark streak represents a 150 million kilometer-long shadow created by the dense hydrogen envelope around the comet's nucleus, indicating a water production rate of approximately 300 tons per second. The bright spot is ultraviolet sunlight scattered by the hydrogen cloud surrounding Hale-Bopp.
