Next Monday Merseyside and the rest of the UK will be treated a rare event when the plant Mercury will cross the surface of the sun.
The transit of Mercury occurs only about 13 times every century, and the next one won’t take place until 2019.
Mercury and Venus are the only solar system planets that lie between the Earth and the sun, so they are both the only planets that transit the star as seen from Earth.
The event is due to last around seven and a half hours on Monday, first becoming visible on Merseyside at 12:12pm and ending at 7:40pm.
As Mercury is a small planet it may be hard to see without magnification, so projecting the sun through a telescope onto a piece of card may be your best chance of observing it.
And remember, never look directly at sun!
We will have a weather update later this week on if the weather will allow us to watch the event.
