http://www.pbs.org/nova/sciencenow We can't
see dark matter, and some skeptics doubt its
existence, but many scientists think it makes
up 20-some percent of our universe.
Astronomer Doug Clowe explains how the Bullet
Cluster, a group of galaxies billions of
light years away, may shed some light on this
mysterious stuff.

COSMOS Video News Release
For the first time ever, astronomers have
been creating a three—dimensional map of
how the dark matter is distributed across the
Universe. An international team of
scientists, among them groups from Marseille,
the Max-Planck Institutes and Paris have been
using data from the NASA/ESA Hubble Space
Telescope. The results are published in
nature online of 8 January 2007, and at the
meeting of the American Astronomical Society
in Seattle. This Video News Release discussed
this discovery. More on:

| Hubblecast 05: Hubble finds ring of dark matter |
 |
An international team of astronomers using
the NASA/ESA Hubble Space Telescope has
discovered a ghostly ring of dark matter
formed long ago during a colossal collision
between two galaxy clusters. This is the
first time that dark matter has been found
with a distribution that differs
substantially from the distribution of
ordinary matter. Read more at:
