How to see a once-in-a-lifetime green comet: Mount Everest-sized space rock ... trends now
Tonight, the night sky will be lit up by a once-in-a-lifetime spectacle as the 'Mother of Dragons' comet returns to the solar system.
The 21-mile-wide (34km) comet 12P/ Pons-Brooks, or Pons-Brooks for short, is making its first visit to the inner solar system in more than 70 years.
And the great news is that you won't even need a telescope or any special equipment to see this stunning display.
All you will need is a dark night and some patience to spot the Mount Everest-sized comet with the naked eye as it reaches its brightest point on Sunday.
However, Dr Robert Massey, deputy executive director of the Royal Astronomical Society warns: 'Don't expect it to be dazzlingly bright - the kind of image you see in photographs. It's not going to be like that.'

The comet earned its name as an eruption of the comet's ice volcanoes gave it a distinct horn-like appearance
The Pons-Brooks comet is a periodic comet, meaning its orbit takes it through the solar system on a somewhat regular basis.
It takes 71.3 years for it to make a complete lap of the sun, making it a so-called Halley-type comet which appear in the solar system every 20 to 200 years.
This means opportunities to see the devil comet only come once or maybe twice in a lifetime.
As Pons-Brooks returns to the inner solar system, light from the sun will reflect off the comet's cloud of gas and ice - making it appear to glow brighter.
The comet will reach its maximum brightness as it reaches its closest point to the sun, or its apogee, which will take place tonight.
To see the comet this weekend look to the West in the 90 minutes after sunset, the comet should be below and to the left of Jupiter
At this time the comet might become bright enough to see with the naked eye, although it will still be very faint.
Dr Massey says: 'This is something that might just be visible to the naked eye if you don't have a Moon in the sky, if there's no light pollution and if the weather is really clear, then you might stand a chance.
'But for most of us, we're going to need to pick up a pair of binoculars.'
Since it might be hard to spot, Dr Massey recommends using a star chart or night sky app to help locate it.
Jake Foster, astronomy at the Royal Observatory Greenwich, told MailOnline: 'The comet will appear low in the west after sunset, setting below the horizon around 90 minutes after the Sun does.
'This means it will be difficult to observe, but not impossible. It will be just below and to the left of Jupiter, which will appear as a bright white dot to the naked eye.
Although the comet will be at its brightest, it may still be quite hard to see as the lighter evenings reduce its visibility.
Mr Foster says: 'Spotting the comet will require a clear view of the western horizon and a pair of binoculars or a telescope.
'Getting away from the light pollution of bright city lights will also help.'
The comet should be visible as a white spot to the naked eye, while telescopic photographs like this can reveal the swirling clouds of gas and dust that surround the nucleus
