This one's my favorite. Each one of those dots and spots is a single galaxy.
Gravitational Lensing in Galaxy Cluster Abell 370
The Hubble Space Telescope’s newly repaired Advanced Camera for Surveys (ACS) has peered nearly 5 billion light years away to resolve intricate details in the galaxy cluster Abell 370.
Abell 370 is one of the very first galaxy clusters where astronomers observed the phenomenon of gravitational lensing, where the warping of space by the cluster’s gravitational field distorts the light from galaxies lying far behind it. This is manifested as arcs and streaks in the picture, which are the stretched images of background galaxies.
Gravitational lensing proves a vital tool for astronomers when measuring the dark matter distribution in massive clusters, since the mass distribution can be reconstructed from its gravitational effects.

Thank you so much Claudia. May it serve as a quick reminder that we are really nothing in the overwhelming magnitudes of the universe and that we must strive to make the best use of our time and the miracle of the spark of life in our tiny fragile bunch of atoms and molecules: let's make an effort to become better friends, better parents, better sons and daughters, better brothers and sisters, and of course better translators.
Take care everyone!

This morning I saw a simply astonishing... marvellous Butterfly-kind pic taken by Hubble... check it out!
ciao from Sicily

The second photo looks like the Verrio ceiling at Hampton Court Palace only more heavenly!
