Explanation:
G1, pictured above, is the brightest known
globular cluster in the whole
Local Group of galaxies. Also called Mayall II,
it orbits the center of the largest nearby galaxy:
M31.
G1 contains over 300,000 stars and is almost as
old as the entire universe.
In fact, observations of this
globular cluster show
stars as old as the oldest of the roughly 250 known
globular clusters in our own
Milky Way Galaxy.
This image
was taken with the
Hubble Space Telescope in July of 1994.
It shows, for the first time, the same fine detail in a
distant globular cluster
as can be discerned from a ground-based telescope of a
globular cluster in
our own Galaxy.
