A nebula is a large cloud of gas and dust in space. It is the birthplace of stars, where gravity pulls the gas and dust together to form a protostar. There are different types of nebulas, such as emission nebulas, reflection nebulas, and planetary nebulas. Emission nebulas are lit up by ionized gas, while reflection nebulas reflect the light of stars. Planetary nebulas are formed when a red giant star expels its outer layers into space, creating a glowing shell of gas. Nebulas are an essential part of the life cycle of stars and our understanding of the universe.

A nebula is a large, generally diffuse cloud of gas and dust, primarily composed of hydrogen, in space. These celestial objects are often located in the early stages of star formation, as the gravity of the material brings it together and begins to compress, ultimately leading to the ignition and birth of new stars. Nebulae can take on a wide variety of shapes and sizes, from small, locally dense regions just a few times the size of our solar system, to vast, spread-out clouds hundreds or thousands of light-years across. Some nebulae, such as those in our Milky Way galaxy, can be visible to the naked eye as faint, glowing patches in the night sky, while others are too distant or too small to be seen without the aid of telescopes. Studying nebulae provides important insights into the processes of star and planet formation, as well as the composition and structure of our universe.
