Quote:
This smiley face hovering in space looks like it was beamed into the heavens by a celestial keyboard. Captured by the Hubble Space Telescope, it was in fact created by a quirk of general relativity known as gravitational lensing.

The glowing eyes are bright galaxies that are part of a galaxy cluster known as SDSS J1038+4849. The massive structure warps space-time, bending light like a lens to create a stretched image of distant galaxies, called an Einstein ring. The well-positioned circular shape creates the outline of the face and the wry grin.
