Passing comet to be visible from Australia

Sally Sara: If it meets the highest expectations of stargazers, a comet passing by Earth could put on a show the likes of which hasn't been seen in years. Nick Grimm: Michael Mattiazo has been rising well before dawn in recent weeks to keep a close eye on a visitor from outer space. Nick Grimm: Professor Jonti Horner from the University of Queensland says the comet will soon disappear behind the sun before becoming visible again by mid-October. Nick Grimm: And likely to be close to the best comet out of the hundreds witnessed and photographed by amateur enthusiast Michael Mattiazo, if it lives up to expectations. Sally Sara: That's amateur astronomer there, Michael Mattiazo, ending that report from Nick Grimm.
