NASA calls this Hubble photo of three merging galaxy clusters; a snowstorm of galaxies.  I counted 9 stars, in this incredible image, every other light source is a galaxy each containing billions of stars. The many thin stretched out blue lines are "lensed" galaxies behind the massive cluster which bends spacetime allowing us a peek at what's behind it.  The photons that created this Hubble image left their creator stars a billion years before our solar system was created.  Have a great weekend!
