A Rare Quadruple Supernova, Revealed by a Quirk of Einstein

The star had been in hiding. A galaxy sat halfway between it and us, eclipsing it from the Earth's point of view. But when it went supernova last September, astronomers caught the image of the concealed explosion anyhow, all thanks to a cool trick of physics.
Because of a bizarre effect called gravitational lensing explained by Einstein's theory of general relativity, scientists caught four separate images of the supernova in a single picture. Stranger still, the faraway supernova—it lies more than 4.4 billion light years from home—was naturally magnified by 5,000 percent when the scientists first saw it.http://www.popularmechanics.com/space/deep-space/news/a26164/quadruple-supernova/

There is danger from all men. The only maxim of a free government ought to be to trust no man living with power to endanger the public liberty.
Public virtue cannot exist in a nation without private, and public virtue is the only foundation of republics. There must be a positive passion for the public good, the public interest, honour, power and glory, established in the minds of the people, or there can be no republican government, nor any real liberty: and this public passion must be superior to all private passions. John Adams
