Hubble's latest images reveal the detail of a super-rich galaxy cluster called Abell 1413. And isn't it damn pretty?
Nestled between the constellations of Leo (The Lion) and Coma Berenices, this collection of over 300 galaxies is over 2 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 2 billion years for us to take this image. Who knows what it actually looks like now. [ESA]
