The Very Large Telescope

Set on a remote and inhospitable mountain in Chile’s Atacama Desert, the Very Large Telescope (VLT) is actually an array of four large telescopes. The telescopes can be operated together to achieve an angular resolution so precise that the array could theoretically be used to distinguish between the two headlights of a car on the Moon. The VLT captured the first image of a planet outside the solar system. What do the four telescopes’ names mean in the local Mapudungun language? Discuss

Population Bottlenecks

Cheetahs are basically all the same. Any two randomly selected cheetahs will be so similar genetically that a skin graft from one will likely provoke no immune response in the other. In the distant past, cheetahs underwent a population bottleneck—an evolutionary event in which a species nearly dies out and is repopulated by a few individuals whose genes are then disproportionately reflected in the ensuing generations. All humans can trace their ancestry back to a single woman. When did she live? Discuss

The Four Horsemen of the Apocalypse

One of the most important silent films of all time, The Four Horsemen of the Apocalypse established actor Rudolph Valentino as a superstar, inspired a tango craze, and beat out Charlie Chaplin’s The Kid to become the highest-grossing film of 1921. It is considered to be among the first anti-war films ever made, and its success made producer June Mathis a powerful woman in Hollywood. Why does Valentino scornfully cast aside his partner at the end of the film’s famous tango scene? Discuss
