A Clash of Clusters Provides New Clue to Dark Matter |
|
A powerful collision of galaxy clusters has been captured by NASA's Hubble Space Telescope and Chandra X-ray Observatory. The observations of the cluster known as MACS J0025.4-1222 indicate that a titanic collision has separated the dark from ordinary matter and provide an independent confirmation of a similar effect detected previously in a target dubbed the Bullet Cluster. These new results show that the Bullet Cluster is not an anomalous case. |

Around The Institute
Spring Symposium 2008
The universe is more complex than we imagined it to be a decade ago. Observations now indicate that the expansion of
the universe is accelerating. It is as if the universe is filled with a sea of "dark energy," the pressure of which
counteracts the pull of gravity on large scales. The past decade marked the discovery of dark energy and the revelation
of our profound ignorance of the cosmos, and dark-energy research over the next decade may well lead the way to a deeper
understanding of the laws of physics. The Space Telescope Science Institute's 2008 Spring Symposium, "A Decade of Dark Energy", will focus on cutting-edge issues in the study
of dark energy. Read more...
Hubble Servicing Mission 4
Hubble precisely measured the age of the universe. It found evidence of dark energy. It brought you images of distant
galaxies in the young universe. And now, with the state-of-the-art instruments delivered by Servicing Mission 4 (SM4),
the Hubble Space Telescope will look onto the universe with new eyes, surpassing even its previous vision. Hubble was
designed to be repaired and upgraded by astronauts, and these servicing missions have occurred several times since
Hubble’s launch in 1990. NASA has selected a crew for the upcoming servicing, and the astronauts have begun
training. Read more...
Call for Papers on Lunar Science with HST
In November 2006, STScI hosted a workshop entitled "Astrophysics Enabled by the Return to the Moon" in support of NASA's Vision
for Space Exploration. STScI is now interested in exploring opportunities for lunar science programs that utilize the Hubble
Space Telescope (HST) in conjunction with a new Lunar Science Initiative that will involve at least 30 orbits of telescope
time during the upcoming Cycle 18. White papers outlining potential science programs that would make use of this time are
now being solicited. Read more...
Caroline Herschel Visitor Program
An invitation is extended to all distinguished astronomers from the United States and the international astronomy community,
with a special emphasis on attracting women and other underrepresented groups, to spend up to three months at the Space Telescope
Science Institute. During that time you will work on and lecture on scientific projects and provide active mentoring to STScI junior
scientists (especially women and other groups underrepresented in the astronomy community). Read more...
The Space Telescope Science Institute is operated for NASA
by the Association of Universities for Research in Astronomy.
