Saturn's moon Titan is the only other body in the solar system with a working weather cycle on its surface — rain, rivers, and seasonal lakes made of liquid methane at minus 179 degrees Celsius. Here's how the machinery works, and why its rivers refuse to build deltas.
In September 1928, a contaminated petri dish in a cluttered London lab produced the halo of dead bacteria that launched the antibiotic era — and the story of how Alexander Fleming's messy bench changed medicine is stranger than the schoolbook version.
In September 1854, physician John Snow persuaded a London parish board to remove the handle from a Broad Street water pump, ending a cholera outbreak that had killed 616 people and founding the science of modern epidemiology.
On October 24, 1946, a captured Nazi V-2 rocket launched from White Sands carried a 35mm cine camera to 65 miles above the New Mexico desert and returned the first photographs ever taken of Earth from space — eleven years before Sputnik reached orbit.
Lunokhod 1 rolled onto the Moon in November 1970, driven by a shift-rotating crew watching stuttering black-and-white television from Crimea. Its French-built laser reflector vanished from Earth's tracking data for nearly 40 years — until a UC San Diego team, using fresh coordinates from NASA's Lunar Reconnaissance Orbiter, bounced a beam off it in April 2010.
