Christmas comes early for Australian fun astronomers, with no space glasses but two for Friday night.
Comet's Christmas and Gemin meteor showers light the night sky light within a few hours.
Christmas Comet – named for time of the year – appears from 9pm AEDT as a green and boring comet in the east, close to the contrast of the name Orion, or Saucepan, says the ANU astronomer, Dr Brad Tucker.
"The green color comes from the gas that comes off the comet," said Dr Tucker at AAP.
"There's a lot of ice on it and methane – it's like a dirty snowball and so when it goes around the sun, it melts … and it's a sticky glow. "
This will be a rare opportunity for Australians to have an insight into the comet, which appears once once every five years.
Lighting hours later flash over the air as the Earth passes through the 3200 Phaethon asteroid tail.
They will look stunning of the ground, but the stars fall only in the atmosphere of the Earth by small rocks that have broken off the asteroid before burning up.
"They are about sand grain size, or even small stones and they travel tens of thousands of kilometers per hour," said Dr Tucker.
Although observers need a pair of binoculars or telescope to hold the Christmas Comet, the meteoric shower will be visible anywhere in Australia, even big cities, as long as it's a clear night.
"It's very accessible, you do not need anything special, you just have the night sky," said Dr Tucker.
