Nebulae are clouds of gas and dust in space, made up of elements like hydrogen, helium, and carbon.
There are different types of nebulae, including emission nebulae, reflection nebulae, and planetary nebulae.
Emission nebulae are usually red or pink and are often associated with star-forming regions, while reflection nebulae appear blue and are caused by dust reflecting starlight.
Planetary nebulae are formed when a low-mass star like our Sun runs out of fuel and sheds its outer layers, leaving behind a small, dense core known as a white dwarf.
The famous Crab Nebula is a supernova remnant, the result of a massive star exploding in a supernova event.
The Orion Nebula is one of the closest and brightest nebulae visible from Earth and is home to many young stars and protoplanetary disks.
Nebulae can also be observed in other galaxies, and some of the most impressive examples are found in the Large and Small Magellanic Clouds.
The gas and dust in nebulae can serve as the raw material for new star formation and even the formation of planets.
Some nebulae have been found to contain complex organic molecules, including amino acids, which are important building blocks of life.
