NGC 735 facts for kids
NGC 735 is a beautiful spiral galaxy found in the Triangulum constellation. It is incredibly far from our own Milky Way galaxy, about 213 million light-years away. Imagine how vast space is!

What is NGC 735?
NGC 735 is a type of galaxy shaped like a giant pinwheel. It has a bright center and swirling arms made of stars, gas, and dust. This galaxy is part of the huge universe we live in. Scientists study galaxies like NGC 735 to learn more about how the universe works.
Where is NGC 735 Located?
NGC 735 is located in the Triangulum constellation. A constellation is a group of stars that form a pattern in the night sky. The Triangulum constellation is named after its triangle shape. Even though NGC 735 is in this constellation, you cannot see it with your eyes alone. You would need a powerful telescope to spot it.
The Triangulum Constellation
The Triangulum constellation is one of the 88 official constellations. It is a small constellation in the northern sky. It is best seen during the autumn months in the Northern Hemisphere. The stars that make up this constellation are not actually close together in space. They just appear to be from our view on Earth.
How Far Away is NGC 735?
NGC 735 is about 213 million light-years from Earth. A light-year is a way to measure huge distances in space. It is the distance light travels in one year. Light travels incredibly fast, about 300,000 kilometers (186,000 miles) per second! So, 213 million light-years is an enormous distance.
Understanding Light-Years
When we look at NGC 735, we are actually seeing it as it was 213 million years ago. This is because the light from the galaxy has taken that long to reach us. It is like looking back in time! This helps astronomers study the history of the universe.
Exploring Spiral Galaxies
Spiral galaxies are one of the most common types of galaxies in the universe. Our own galaxy, the Milky Way, is a spiral galaxy. They are known for their beautiful, swirling arms. These arms are where many new stars are born.
How Do Spiral Galaxies Form?
Scientists believe that spiral galaxies form from huge clouds of gas and dust. Over time, gravity pulls this material together. As it spins, it flattens into a disk shape. The denser parts of the disk form the spiral arms. Stars then begin to form within these arms.
Different Kinds of Spirals
Not all spiral galaxies look exactly the same. Some have very tightly wound arms, while others have loose, open arms. Some even have a bar-shaped structure in their center, like our Milky Way. These are called barred spiral galaxies. NGC 735 appears to be a regular spiral galaxy without a prominent bar.
Discovering Galaxies
Galaxies like NGC 735 are often discovered using powerful telescopes. Astronomers use these tools to look deep into space. They take pictures and study the light coming from distant objects. This helps them identify new galaxies and learn about their properties.
The New General Catalogue (NGC)
NGC 735 gets its name from the New General Catalogue. This is a famous list of deep-sky objects. It was put together by John Louis Emil Dreyer in 1888. The catalogue includes thousands of galaxies, star clusters, and nebulae. Many objects in space are still known by their NGC numbers today.
Why Study Distant Galaxies?
Studying distant galaxies helps us understand the universe. It tells us about how galaxies form and change over time. It also helps us learn about the early universe. By looking far away, we are also looking back in time. This is like finding clues to the universe's past.
