Today, Tuesday 25 October, marks the one and only solar eclipse of 2022 that is visible from the UK. Sky watchers will be able to see the partial solar eclipse from areas of Europe, Western Siberia, Central Asia, Western Asia, South Asia and the north-east of Africa.
This is everything you need to know about how to make the most out of the rare natural phenomenon.
How to view a solar eclipse safely?
There are a number of ways that you can make viewing the phenomenon safe.
The Royal Astronomical Society (RAS) says that “a simple yet safe way to view a solar eclipse” is by making a pinhole camera.
All you need to make your own pinhole viewer are two pieces of white card.
Poke a small hole in one piece of card and when the eclipse is happening, stand with your back to the sun.
Hold both cards up, with the one with the hole closer to the sun. The light through the pinhole will be projected onto the other piece of card, making the eclipse safe to view.
You can do a similar thing with a cereal box. Make a pinhole in one edge, point it towards the sun and you’ll see a small image of the sun projected on the inside of the box.
Alternatively, you can safely view the eclipse by watching a livestream of the event - the NASA YouTube channel is broadcasting the phenomenon.
The National Safety Council states that you should not use ordinary sunglasses - even very dark sunglasses - or look at the sun through a camera, telescope, binoculars or other optical device.
Why can’t I just look at the eclipse?
While the eclipse today is actually a partial eclipse, you still need to take care when viewing it, otherwise you can risk damage to your eyes.
RAS says that it “is extremely dangerous to just go out and look up”.
“The sun is so bright that just looking at it can blind you, so you’ll need to prepare beforehand,” RAS says.
RAS explains that “viewing an eclipse is dangerous because the sun’s photosphere emits very intense visible light that can damage the light sensitive retina at the back of your eyes if you look directly at the sun without proper protection”.
It adds that “you only need to luck at the sun for a few seconds for your eyes to become permanently damaged”.
