Christmas will come earlier to Australia's astronomers, without the cosmic glasses scheduled for Friday night.
The Christmas comet and the jammed meteor shower should light the night sky just a few hours apart.
The Christmas Comet, which is said to be the year of the year, is expected to be released at 21:00. As a green and fuzzy comet to the east, near the constellation known as Orion or Sapucan, it says the astronomer of the AUB, Dr. Brad Tucker,
"The green color comes from the gas coming from the comet," Dr. Tucker told AAP.
"There is a bunch of ice and methane on it – it's basically like a dirty snowball, so when it drops into the sun it melts … and it's hot, shining green light."
This would be a rare chance for Australians to come across the comet, which only occurs once every five years.
Hours later, shooting stars are set to blink in the sky as the Earth passes through the tail of the 3200 Phaethon asteroid.
They will look impressive from the ground, but the falling stars are actually just small rocks that have separated from the asteroid before they are burned in the earth's atmosphere.
"They are about sand or even a little pebble, and they travel at tens of thousands of miles per hour," said Dr. Tucker.
While observers will need a pair of binoculars or a telescope to catch Christmas Comet, the meteor shower will be visible from anywhere in Australia, even the big cities until it's clear night.
"It's very affordable, you do not need anything special, you just need the night sky," said Dr. Tucker.
Will you see Aussey's spatial spectacle?
If you're ready to catch this once during a lifetime sky show, pay attention to the weather conditions in the big city.
A cloudy night is predicted on Friday, but while it is expected rain in the afternoon and evening, it should be clear in time for the comet and meteorite around 9pm AEDT.
Expecting a cloudy night, along with the possibility of a thunderstorm.
There is a cloudy night, although the worst of a possible heavy thunderstorm earlier in the day had to pass.
A high chance of rain and a thunderstorm will leave ACT with little chance of seeing a comet or meteor shower.
Those who live in the "Hot End" may have a chance to see the stars by warning for a night forecast before a thunderstorm.
It is expected that the clouds will sneak through the sky at night, with a chance for Saturday's thunderous forecast of the city.
A cloudy night sky is expected after a day of showers, which will make it easier for the sun to descend.
Partly cloudy night will cover the night sky with a medium probability of rain.
