Hubble's latest images reveal the detail of a super-rich galaxy cluster called Abell 1413.
Nestled between the constellations of Leo (The Lion) and Coma Berenices, this collection of over 300 galaxies is over two billion light-years from Earth. This particular image is dominated by a large elliptical galaxy called MCG+04-28-097, and the stars surroundings it are up to 6.5 million light years from it.
As ever, those numbers are bewildering. It took two billion years for the light to reach us to take this image. Who knows what it actually looks like now. [ESA]
