Astrobiology – the study of life on other planets – has grown from a fringe sub-discipline of biology, chemistry and astronomy to a leading interdisciplinary field, attracting researchers from top institutions across the globe, and large sums of money from both NASA and private funders. But what exactly is it that astrobiologists are looking for? How will we know when it’s time to pop the Champagne?…

As we look for life, we might send inventive birthday greetings to William “Willy” A. Higinbotham; he was born on this date in 1910. A physicist who was a member of the team that developed the first atomic bomb, he later became a leader in the nuclear non-proliferation movement.
But Higinbotham may be better remembered as the creator of Tennis for Two, the first interactive analog computer game and one of the first electronic games to use a graphical display, which he built for the 1958 visitor day at Brookhaven National Laboratory. It used a small analogue computer with ten direct-connected operational amplifiers and output a side view of the curved flight of the tennis ball on an oscilloscope only five inches in diameter. Each player had a control knob and a button.
