NGC 5139 - Globular Cluster Omega
Centauri |
|
Description of object:
Omega Centauri is the largest globular cluster of our galaxy. It
contains far more than 1 million stars in a spatial volume of 150 light years
diameter. In its center the density of stars is 40 times higher than close to
the sun. The distance from the earth is approximately 17000 light years. Recent
studies show that Omega Centauri is probably the remnant of a former dwarf
galaxy, whose outer stars were absorbed by the milky way. It is possible to
clearly see this star cluster as a fuzzy spot in the sky. The brightest part of
the cluster covers an area of the size of the moon.
It is fascinating to look at Omega Centauri through a
telescope and see thousands of tiny stars on a black, velvety background. It is
an experience not to be missed. This is one of the first images taken with 17"
