A RARE alignment of six planets - Jupiter, Mercury, Uranus, Mars, Neptune and Saturn - is set to occur in the skies tonight.
The cosmic phenomenon will be partially visible and here's how you can best view it.
According to experts, the upcoming alignment will be tricky to spot - but not impossible.
The rare alignment will take place in the night sky from June 3 into June 4, though part of it will be hidden behind the horizon.
But Mars and Saturn will be the easiest to see with the naked eye, experts expect.

The best chance of seeing any of it is before sunrise, which will happen between 4.30am and 5am in the UK.
It's a similar story in the United States, where you'll want to look up between 30 and 60 minutes before sunrise.
In New York City, sunrise will be 5.26am on June 4, or 5.42am in Los Angeles.
So it'll be an early wake-up if you want to catch a good view of the alignment.
"Seeing the alignment will indeed be challenging as it happens around sunrise and it’s all rather low in the East as well," Professor Danny Steeghs, Department of Physics, University of Warwick, explained.
This visual phenomenon differs from an astronomical alignment, where planets gather simultaneously on the same side of the sun.
How to spot
Those hoping to see the display will only be able to do so if they have a clear sky and a nearly flat western horizon.
It's key to make sure the sky is free of obstructions like trees or buildings.
For the best view, stargazers have been advised to use binoculars.
However, specialist equipment may be needed to spot Uranus and Neptune.

"Uranus and Neptune will be faint, so viewers will require good binoculars to see them," Steeghs added.
"Jupiter and even Mercury are very close to the Sun, restricting their view.
"Mars and Saturn are the more accessible ones to view, you can see them ahead of the other planets rising and a bit higher in the sky."
To help identify the planets, Steeghs recommends using an app to guide you.
Experts have previously suggested the app Sky Tonight.
The app can be pointed at any area of the night sky to give a live display of what is going on up there - even if it's daylight.
