Northern Cross (asterism)

Hey kiddo, do you remember looking up at the stars and seeing some of them form a shape that looks like a cross in the sky? That's called an asterism, which is just a fancy word for a recognizable pattern of stars. The northern cross is one of these patterns, and it's made up of five really bright stars that are visible in the northern hemisphere.

The northern cross is also known as Cygnus, which is the name of a mythical swan that the pattern is supposed to represent. Do you see how some of the stars look like a bird's wings and neck? That's why it's sometimes called the Northern Cross of Cygnus.

The stars that make up this asterism are called Deneb, Albireo, Sadr, Gienah and Delta Cygni, and they’re part of the Cygnus constellation. These stars are really important because they can help us find our way around the sky, especially if we're lost or trying to navigate with a map.

So, whenever you look up at the night sky, try to find the northern cross and remember that it's more than just a pretty shape in the sky. It's part of a bigger picture that helps us explore and understand our universe!
