Lucky imaging

Lucky imaging is like taking a picture with a camera lens, but instead of taking just one picture, you take lots and lots of pictures really fast in a row.

Sometimes, when you take pictures with a camera, the pictures can come out blurry or not very clear because the camera was moving or because the subject was moving. But with lucky imaging, you take so many pictures so fast that you can pick out the ones that are the clearest and use those.

It's like if you were playing a game of tag and you had to catch your friend who was moving really fast. If you tried to just tag them once, you might miss and not be able to catch them. But if you tagged them lots and lots of times really fast, you would have a better chance of tagging them at least once.

Scientists use lucky imaging to study things like stars and planets because they can take lots of pictures in a row really fast and then pick out the ones that are the clearest. This helps them see more details and learn more about what they are studying.
