Take a spaceship journey to a galaxy cluster five billion light-years away


Annotated image of the field around CLASS B1608+656

Most of the galaxies visible in this Hubble image are members of a
huge cluster called CLASS B1608+656, which lies about five billion
light-years away. But the field also contains other objects that are
both significantly closer and far more distant — including two
gravitational lenses dubbed Fred and Ginger.

These contain enough
mass to visibly distort the light from objects behind them. Fred, also
known more prosaically as [FMK2006] ACS J160919+6532, lies near the lens
galaxies in CLASS B1608+656, while Ginger ([FMK2006] ACS J160910+6532)
is markedly closer to us. Despite their different distances from us,
both can be seen near to CLASS B1608+656 in the central region of this
Hubble image, and are labelled.
