** 1E0657-56: A Bow Shock in a Merging Galaxy Cluster
Chandra’s image of the extremely hot galaxy cluster 1E0657-56 reveals a
bow-shaped shock wave toward the right side of the cluster. This
feature, thought to be the result of the merger of a smaller group or
sub-cluster of galaxies with 1E0657-56, gives astronomers a rare
opportunity to study how clusters grow.

** Chandra Chronicles: A Full Dance Card For Chandra Science
Astronomers from all over the world assembled last month in Washington,
D.C. for the bi-annual meeting of the American Astronomical Society
(AAS). Gathered to exchange and discuss the very latest results and
discoveries, scientists met for over four full days, with daily science
poster displays, oral presentations, press conferences, and an extensive
exhibit hall showcasing all manner of astrophysical science endeavors.

** OUT OF THE NOISE: A Cosmic Effect
“Why should we care what happens in our galaxy and beyond? Sure it’s
nice to know something about galaxies, black holes, supernovas, etc.,…
but it’s all so far away and there are so many pressing problems on
Earth that need our attention!” Granted, there are lots of problems
here on Earth that are deserving of attention, but that’s not the point.
We are in fact very much affected by the cosmic environment that we
inhabit.

** Operations CXO Status Report (Friday 02/15/02)
During the last week, Chandra completed the observing schedule as
planned. Chandra passed through eclipses 4, 5 and 6 of the 2002 Spring
season on Feb 8, 11 and 13 with nominal power and thermal performance.
A routine real-time procedure was completed on Feb 11 to update the
on-board the Ephemeris.

NEW & NOTEWORTHY!
++ Chandra in 2001
Now in its third year of observation, Chandra has observed not only
strange stars, but black holes, galaxies, and other cosmic phenomena.
Taking a look back, here are some of the highlights of the past year
with Chandra.
