How does a solar system throw a party? They planet.
No but seriously - almost the entire solar system will be visible in the sky on tonight - part of an incredible rare 'planetary parade'.
Five planets are set to align with the moon across the sky on Tuesday (28 March) and there is a possibility to view the alignment from anywhere on Earth.
As long as the weather is clear and there's not too much pollution, chances are you might get a good view - and you certainly won't want to miss it.
Jupiter, Mars, Mercury, Uranus, Venus and the Moon only ever align like this every few years, experts have said. It last happened in 2020, and before that in 2016.
However, astronomers have warned that not all of the planets are easy to spot.
Professor Beth Biller, of the University of Edinburgh, told MailOnline: "Exact location in the UK is probably not critical. What is more important is to be out of the city and to be somewhere where you have a good view of the horizon.'
In the UK capital, here are the best times if you want to catch a glimpse in London tonight:
Mercury: Until Tue 20:30
Venus: Until Tue 22:56
Mars: Until Wed 03:16
Jupiter: Until Tue 20:21
Uranus: Until Tue 23:04
Saturn: From Wed 05:52
Neptune: From Wed 06:31
Professor Biller added: "Venus and Jupiter are both very bright and easy to pick out and you may have already seen them close together over the past few weeks.
"Mars is a bit fainter, but still easily observed with the naked eye. Mercury starts getting tricky - you need to be at a dark site with a clear view of the horizon if you want to see Mercury."
While Anna Gammon-Ross, an astronomer at the Royal Observatory in Greenwich, explained: "The best time to see these five planets tonight is just after sunset.
"If you look in the direction the sun has set (the west), low in the sky you can spot Jupiter and Mercury close to each other.
"A bit higher up and a little further to the south, you'll be able to spot Venus, and high in the south you'll be able to see Mars, close to the moon."
She added: "All these planets are visible just using your eyes and will look like bright points of light. They'll appear slightly different to stars because stars twinkle and planets don't.
"To spot the fifth planet up at this time, Uranus, you will need to look close to Venus using a telescope."Featured Image Credit: Stocktrek Images, Inc. / Chesh / Alamy
