NGC 740 facts for kids
NGC 740 is a fascinating barred spiral galaxy located in the Triangulum constellation. It is very far away from our own Milky Way galaxy, about 212 million light-years distant. Imagine how long it takes for light from NGC 740 to reach us!

What is NGC 740?
NGC 740 is a galaxy, which is a massive group of stars, gas, and dust. These are all held together by gravity. Galaxies come in many shapes and sizes. NGC 740 is named after the "New General Catalogue" (NGC). This is a list of many different deep-sky objects.
Barred Spiral Galaxies
NGC 740 is a special type of galaxy called a barred spiral galaxy. Imagine a giant pinwheel in space. That's what a spiral galaxy looks like! It has long arms that spin out from a central bulge. In a barred spiral galaxy, there's a straight bar of stars right through the middle. The spiral arms then start from the ends of this bar. Our own Milky Way galaxy is also a barred spiral galaxy!
Where is the Triangulum Constellation?
NGC 740 is found in the Triangulum constellation. A constellation is a group of stars that form a pattern in the night sky. People often name these patterns after animals, objects, or mythical figures. Triangulum means "triangle" in Latin. It's a small constellation that looks like a narrow triangle. You can find it in the northern sky.
How Far is 212 Million Light-Years?
When we say NGC 740 is 212 million light-years away, it means the light we see from it today started its journey 212 million years ago! A light-year is the distance light travels in one year. Light moves incredibly fast, about 300,000 kilometers (186,000 miles) per second. So, 212 million light-years is an enormous distance. It helps us understand just how vast the universe is.
