A spot of stargazing
week’s Transit of Venus was a once-in-alifetime astrological event. It will be more than a century before the next one. Astronomers were as keen to study the event this week as Lieutenant James Cook’s expedition was in 1769. Then, the observation from the island of Tahiti was to be a yardstick for measuring the entire solar system. Now, astronomers hope to discover exoplanets. Science series Catalyst features reports on the phenonemon filed by Graham Phillips, aboard the Australian Maritime Museum’s replica of the Endeavour at Lord Howe Island and Mark Horstman, joining stargazers at Sydney Observatory. Catalyst also reports on at-home genetic test kits; wearable robots and what’s in a cat’s purr.
