Sperms were observed for the first time in 1677


The observation was made by the Dutch microscope-maker Antonie van Leeuwenhoek, using a sample of his own semen. He reported seeing "animalcules" moving like eels (and was quick to assure his readers that the sample came from an "excess" left over from conjugal relations rather than from masturbation)

A near-perfect Einstein ring 12 billion light years away!


This image features an active star-forming galaxy, which appears magnified and ring-like due to a strange phenomenon called gravitational lensing and predicted by Einstein's theory of general relativity. None of this would be visible from Earth without the incredible resolution of the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile
