Explanation:
This
deep field mosaicked image
presents a stunning view of galaxy cluster Abell 2744 from
the James Webb Space Telescope's NIRCam.
Also dubbed Pandora's Cluster, Abell 2744 itself
appears to be a ponderous merger of three different massive galaxy clusters
some 3.5 billion light-years away toward the constellation Sculptor.
Dominated by dark matter,
the mega-cluster warps and distorts
the fabric of spacetime,
gravitationally
lensing
even more distant objects.
Redder than the Pandora cluster galaxies
many of the lensed sources are very distant galaxies in the early
Universe, stretched and distorted into arcs.
Of course distinctive
diffraction spikes mark foreground Milky Way
stars.
At the Pandora Cluster's estimated
distance this cosmic box spans about 6 million light-years.
But don't panic.
You can explore the tantalizing region in a
2
minute video tour.
