stunning image



May 11, 2000

For 1-1/2 years, the Hubble Heritage Program has offered the public a monthly visual treat, a sumptuous picture taken by NASA's Hubble Space Telescope.

Now the Heritage program has received a treat of its own. The International Center of Photography (ICP) in New York City will present the Sixteenth Annual Infinity Award for Applied Photography to the Heritage program at an awards ceremony May 11. The Heritage program team, composed of astronomers and other technical experts, is based at the Hubble telescope's science operations center, the Space Telescope Science Institute in Baltimore, Md.

The Infinity Awards, which are given in eight categories, honor excellence in the field of photography and writing. The Applied Photography category encompasses architectural, fashion, and scientific photography. The awards' selection committee, consisting of an international team of photography experts, cited the project for valuing "both scientific information and aesthetic presence" in producing celestial photographs.

Hubble Heritage Program Scientist Keith Noll is pleased that the committee understands the project's dual purpose of creating beautiful photographs without sacrificing scientific details.

"These are not just fluff photographs," he says. "We plan all our observations, keeping in mind the immense scientific value of Hubble images. We want the end products to be both beautiful images and research papers, and this has already happened."

Adds Jayanne English, one of the Heritage program's image processing specialists: "We attempt to preserve the scientific integrity of a celestial object while enhancing it visually. They're not mutually exclusive. For example, we may take a well-known image and rotate it, so that it's not the same orientation astronomers are accustomed to seeing in the astronomy catalogues of celestial objects. That small change can make the image more dynamic and adds depth."

The Hubble Heritage program provides the public with some of the very best celestial snapshots taken by the orbiting observatory's visible-light camera, the Wide Field and Planetary Camera 2. The team produces a new picture every month by either mining the rich feast of images in the telescope's archive or using Hubble to make new observations of heavenly bodies that were selected by the public.

"Although astronomers don't usually make the comparison, Hubble is, essentially, a giant digital camera in orbit," Noll says. "What makes using Hubble different is that we need a lot of specialized skills to make beautiful images."

One won't find any past winners in the Applied Photography category using a camera that comes close to the size and breadth of Hubble's visible-light camera. The past winners include some of the biggest names in photography, including Annie Leibovitz, whose work has appeared in "Rolling Stone," "Vogue," and "Vanity Fair."

ICP, founded in 1974 by photojournalist Cornell Capa, celebrates photography's diversity through exhibitions, educational programs, and collections.

Hubble Heritage team members are Keith Noll, Howard Bond, Carol Christian, Jayanne English, Lisa Frattare, Forrest Hamilton, and Zolt Levay.


What are the interesting features in this picture?

The spiral arms of the foreground galaxy appear dark where the dust is silhouetted against the light from the more distant galaxy. The bright blue stars forming a pinwheel shape near the center of the foreground galaxy have formed recently from interstellar gas and dust.

A small, red patch near the center of the image is the bright nucleus of the background galaxy. It is reddened for the same reason the setting sun looks red. When light passes through a volume containing small particles (molecules in the Earth's atmosphere or interstellar dust particles in galaxies), its color becomes redder.
