A solar eclipse occurs when the Moon's orbit lines up in between the Sun and the Earth. The Moon blocks out the Sun's light for a short time, casting a shadow on the Earth. It's a rare event and only possible when the Moon is at exactly the right distance from the Earth. When can I see an eclipse in the UK? <br />On Friday 20 March the UK will experience the first eclipse of 2015. Selfie warning for solar eclipse It will be a partial eclipse, so the sky will darken but the Sun will still peek out from behind the Moon. <br /> <br />Never look directly at the Sun: you can damage your eyes forever. <br />Even the small amount of Sun peeking out from behind the Moon during an eclipse is enough to make you go blind. <br />Never look at the Sun through binoculars or a telescope. <br />Don't look directly at the Sun through sunglasses, or exposed photographic film - they will not protect your eyes. <br /> <br />Another way to safely enjoy the eclipse is to make a pinhole camera. This will project an image of the eclipse onto card. <br />You'll need two pieces of card. Make a small hole in the centre one of them - no more than 4mm across. <br />Tilt the card with the hole towards the Sun and use it to project an image of the eclipse onto the other card.
