Few have dared to enter into these forbidden
realms;
few have returned to tell us of them...

TitleA Cosmic Magnifying Glass
Full DescriptionScanning the heavens for the first time
since the successful December 1999 servicing mission, NASA's Hubble Space Telescope imaged a giant, cosmic magnifying glass,
a massive cluster of galaxies called Abell 2218. This 'hefty' cluster resides in the constellation Draco, some 2 billion light-years
from Earth. The cluster is so massive that its enormous gravitational field deflects light rays passing through it, much as
an optical lens bends light to form an image. This phenomenon, called gravitational lensing, magnifies, brightens, and distorts
images from faraway objects. The cluster's magnifying powers provides a powerful "zoom lens" for viewing distant galaxies
that could not normally be observed with the largest telescopes. The picture is dominated by spiral and elliptical galaxies.
Resembling a string of tree lights, the biggest and brightest galaxies are members of the foreground cluster. Researchers
are intrigued by a tiny red dot just left of top center. This dot may be an extremely remote object made visible by the cluster's
magnifying powers. Further investigation is needed to confirm the object's identity. The color picture already reveals several
arc-shaped features that are embedded in the cluster and cannot be easily seen in the black-and- white image. The colors in
this picture yield clues to the ages, distances, and temperatures of stars, the stuff of galaxies. Blue pinpoints hot young
stars. The yellow-white color of several of the galaxies represents the combined light of many stars. Red identifies cool
stars, old stars, and the glow of stars in distant galaxies. This view is only possible by combining Hubble's unique image
quality with the rare lensing effect provided by the magnifying cluster.

Galaxies are pinpoints of light in the vast nothingness of black, empty, Deep Space. Galaxies are nothing...
|
|
|
|
| A train in the woods, on a definite path to nowhere... |

The impact of this
possibility
is enormous. A lense of such immensity
may allow us to see outside of our
enclosed galactic universe of billions
of galaxies into what-- more empty space?
Or something different again? The mind
boggles at the possibilities it cannot
even imagine.
