A Smiley Face Is Out There looking At You,

or I should say us,


it is in fact what 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 space time to warp, effectively distorting the light around it, you can read more about it over on Hubble’s website, the wonders of the universe never cease to amaze me.
