** 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

(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.

We are in fact very much affected by the cosmic environment that we

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
