"Not only is the Universe stranger than we think, it is stranger than we can think"


Werner Heisenberg –German theoretical physicist, awarded the Nobel Prize in Physics for 1932 "for the creation of quantum mechanics."

The galaxy SDP.81 above is seen at a time when the Universe was 15% of its current age, only 2.4 billion years after Big Bang. The light has taken over twice the age of the Earth to reach us (11.4 billion years), detouring along the way around a large foreground galaxy that is comparatively close at 4 billion light-years away from our Solar System. The foreground galaxy is acting as a lens, warping SDP.81’s light and creating a near-perfect example of a phenomenon known as an Einstein Ring.
