Hubble Spots a Cluster of Galaxies That Looks like a Massive Smiley Face

A smiling lens

Hot on the heels of their new and improved Pillars of Creation image, NASA just published a new photo that appears to be the largest happy face in existence. The eyes alone are two different galaxies, SDSSCGB 8842. 3 and SDSSCGB 8842. 4, and the smile is an optical illusion caused by something called strong gravitational lensing, a phenomenon where the gravitational pull of an object is so powerful it causes spacetime to warp, effectively distorting the light around it. You can read more about it over on Hubble’ s website. (via Hubble)
