Two supermoons in August - here's what you need to know!
In August, two supermoons will appear in the skies, the first is tonight, August 1, and it's due to rise at 10pm.
Tomorrow, you can see it from 10.20pm, Wednesday August 2.
There is also a second supermoon at the end of the month, or a 'blue moon', because it's the second full moon in a calendar month.
The term 'supermoon' was only introduced in the 1970s, and has captured people's imaginations ever since.
The supermoon is actually an optical illusion, known as the 'moon illusion'. A supermoon is when the moon is a closer to the earth, but a supermoon doesn't actually look that much bigger in the sky compared to a normal full moon.
It does however, look bigger when it's closer to the horizon. This is known as the moon illusion.
Why should we try and catch a glimpse of a supermoon? It allows the features and shadows of the moon become clearer to the naked eye, and it's even better if you have a camera or a telescope.
It's also just a fun thing to do. So here's hoping for a clear and cloudless night. Happy moongazing everyone!
