A unique poinsettia that has not been seen in 400 years will be visible TODAY – and that’s exactly how you can see it
- The crescent moon passes Jupiter and Saturn and forms a conjunction on December 17th
- Jupiter and Saturn will appear as one star in a “Great Conjunction” on December 21st
- The two planets are said to align themselves close to Earth for the first time in 400 years
- Star gazers can spot the phenomenon around 9 p.m. Australian Eastern Time
- Anyone using a telescope can also see the individual planets and their moons
For the first time in 400 years, a unique poinsettia will adorn the sky on Thursday.
Jupiter and Saturn will align in the night sky on December 21st and appear as a single bright star in a moment known as the “Great Conjunction”.
But Australian stargazers will be able to see the phenomenon as early as Thursday, when Jupiter slowly approaches Saturn, according to the Perth Observatory website.
Matt Woods of the Perth Observatory said that to see the conjunction Thursday, Australians should look south-west low on the horizon between 7:30 p.m. and 9:30 p.m.

The Australian skies will light up with a “one-off” event when Jupiter and Saturn (see picture above) meet in a “grand conjunction” on December 21 at around 9 p.m. (AEDT)

The two planets appear as a bright star in the night sky (example diagram shown)
Jupiter will be “one of the brightest in the west” with the moon and the two planets forming a triangular formation.
Mr. Woods said the last time the rare planetary alignment appeared so close to Earth, “the telescope had just been invented”.
“It gets pretty close every couple of decades, but the last time they were that close was when Galileo was still alive on July 16, 1623,” he said
Mr. Woods said the Grand Conjunction was “visible all over the world” and could be enjoyed by die-hard enthusiasts and the occasional star gazer alike.
“They appear near a star between 7:30 p.m. and 9:30 p.m. (AWST) and you don’t need a telescope to see them,” he explained.
“It’s something people can just go into their backyards and look at.”
The phenomenon will be visible around 9 p.m. on the east coast.
Mr Woods said stargazers using binoculars or a telescope might even be able to see the planets and their individual moons up close.
Both planets will be visible for a week around December 21st.
Saturn’s largest moon, Titan, is the second largest in the solar system and the only place outside of Earth where surface fluid has been found.

Stargazers using a telescope (file image shown) can also see the individual planets and their moons. The phenomenon last occurred around 400 years ago
Mr. Woods also urged stargazers to find a flat and clear area to discover the planets.
“They’re pretty low on the horizon. So if people in the west have buildings or trees on the horizon, it’s better to get out early and take a look,” he explained.
“Or just go to a local park and give it a try.”
Mr. Woods greeted stargazers who joined the Perth Observatory and the Fremantle Sidewalk Astronomy to observe the phenomenon at North Coogee Dogs Beach.
