The astronomers operating the Pan-STARRS1 telescope on the island of Maui were not expecting to hit cosmic paydirt on Oct. 19, 2017but they did.On what was otherwise an ordinary night of skygazing, they suddenly spotted what is easily the oddest comet ever detected.Its high speed87 km per second (54 mi. per second)and highly elliptical angle indicated that it originated from deep space, the first known interstellar object ever to enter our solar system.
