Smiling face in the night sky

Say Cheese !

In the centre of the below image, taken with the NASA/ESA Hubble Space Telescope, is the galaxy cluster SDSS J1038+4849 ... and it seems to be smiling.

You can make out its two orange eyes and white button nose. In the case of this “happy face”, the two eyes are very bright galaxies and the misleading smile lines are actually arcs caused by an effect known as strong gravitational lensing.

Galaxy clusters are the most massive structures in the Universe and exert such a powerful gravitational pull that they warp the spacetime around them and act as cosmic lenses which can magnify, distort and bend the light behind them. This phenomenon, crucial to many of Hubble’s discoveries, can be explained by Einstein’s theory of general relativity.

In this special case of gravitational lensing, a ring (known as an Einstein Ring) is produced from this bending of light, a consequence of the exact and symmetrical alignment of the source, lens and observer and resulting in the ring-like structure we see here.

Wolf Spider

The wolf spider is the only species of spider that carries its offspring this way - live, hatched and wriggling on her back!
After a gestation of 9 to 27 days (dependent on temperature) during which the eggs are carried around in a silk globe attached to the mothers stomach, the offspring hatch and climb on to her back. They stay there until they're ready to hunt alone.
