ALMA Image of a Lensed Galaxy Looks Like the Eye of Sauron
The world's most powerful ground-based observatory, the Atacama Large Millimeter Array (ALMA), has just captured an image of a distant galaxy as a spectacular ring of fire in space:

This image is one of the most detailed photographs ever of a phenomenon called gravitational lensing, which is predicted by Albert Einstein's theory of relativity. As a result of galaxies' massive gravitational force, the spacetime around a galaxy is curved, creating a gravitational field. The gravitational field then bends the light emitting from stars and galaxies, almost like an enormous lens. This particular type of lensing is called an Einstein Ring, and it occurs when the light from two galaxies line up perfectly, forming a circle.

It also happens to strongly resemble an iconic symbol from the Lord of the Rings series, the evil Sauron's official insignia, the Eye of Sauron:
