This NASA/ESA Hubble Space Telescope image was taken with the Wide Field and Planetary
Camera 2 (WFPC2) in red light. The two hour exposure spans 2.5 arcminutes.
The image shows an overview of the massive galaxy cluster Abell 1835 (right) which is acting as
a gravitational telescope enhancing the light from background galaxies. The galaxy cluster is at a
distance of 3.5 billion light years and numerous gravitational arcs can be seen in the image. In the
centre of the cluster a massive giant elliptical galaxy is surrounded by several smaller ellipticals.
The box indicates the galaxy SMM J14011+0252, also called J1/J2, which was first observed with
the SCUBA (Sub-millimetre Common User Bolometer Array) instrument on the James Clerk Maxwell
Telescope in Hawaii.
