 Hubble views a galactic monster

  Summary:
      The NASA/ESA Hubble Space Telescope has captured a monster in
      the making in this observation of the exceptional galaxy cluster
      eMACS J1353.7+4329, which lies about eight billion light-years from
      Earth in the constellation Canes Venatici. This collection of at
      least two galaxy clusters is in the process of merging together
      to create a cosmic monster, a single gargantuan cluster acting as
      a gravitational lens.

FULL STORY
==========================================================================
The NASA/ESA Hubble Space Telescope has captured a monster in the making
in this observation of the exceptional galaxy cluster eMACS J1353.7+4329,
which lies about eight billion light-years from Earth in the constellation
Canes Venatici. This collection of at least two galaxy clusters is in
the process of merging together to create a cosmic monster, a single
gargantuan cluster acting as a gravitational lens.

Gravitational lensing is a dramatic example of Einstein's general theory
of relativity in action. A celestial body such as a galaxy cluster is
sufficiently massive to distort spacetime, which causes the path of light
around the object to be visibly bent as if by a vast lens. Gravitational
lensing can also magnify distant objects, allowing astronomers to observe
objects that would otherwise be too faint and too far away to be detected.

It can also distort the images of background galaxies, turning them into
streaks of light. The first hints of gravitational lensing are already
visible in this image as bright arcs which mingle with the throng of
galaxies in eMACS J1353.7+4329.

The data in this image are drawn from an observing project called
Monsters in the Making, which used two of Hubble's instruments to
observe five exceptional galaxy clusters at multiple wavelengths. These
multi-wavelength observations were made possible by Hubble's Wide Field
Camera 3 and Advanced Camera for Surveys.

The astronomers behind these observations hope to lay the groundwork
for future studies of vast gravitational lenses with next-generation
telescopes such as the NASA/ESA/CSA James Webb Space Telescope.
