NGC 7538 facts for kids
NGC 7538 is a beautiful cloud of gas and dust far out in space. It's a special kind of cloud called a diffuse nebula. You can find it in the constellation known as Cepheus. This amazing space cloud is about 9,100 light-years away from our Earth.

What is NGC 7538?
NGC 7538 is a giant cloud in space made mostly of gas and dust. These clouds are called nebulae (say "NEB-yoo-lay"). This particular nebula is a "diffuse" one, which means its gas and dust are spread out. It's not a tightly packed cloud.
Where is NGC 7538 Located?
You can find NGC 7538 in the constellation of Cepheus. A constellation is a group of stars that seem to form a pattern in the night sky. Cepheus is named after a mythical king.
How Far Away is NGC 7538?
NGC 7538 is incredibly far from Earth. It's about 9,100 light-years away. A light-year is the distance light travels in one year. Light moves super fast, about 300,000 kilometers (186,000 miles) every second! So, 9,100 light-years is a huge distance, showing just how big our universe is.
Why are Nebulae Important?
Nebulae like NGC 7538 are often called "star nurseries." This is because new stars are born inside them! The gas and dust in these clouds slowly pull together due to gravity. As more material gathers, it gets hotter and hotter until a new star begins to shine.
What Happens in a Diffuse Nebula?
In a diffuse nebula, the gas and dust are spread out. But even though they are spread out, they still have enough material to form new stars. The light from nearby stars can make these nebulae glow, which is why we can see them from Earth.
