A cloud of dust and gas where a star is born is called a stellar nursery or a nebula. These clouds are made up of materials like hydrogen and helium that gradually collapse under gravity to form new stars. Examples include the Orion Nebula and the Eagle Nebula.
The Helix Nebula is a planetary nebula located in the constellation Aquarius, while the Ring Nebula is a planetary nebula located in the constellation Lyra. The Helix Nebula appears more like a disk or helix shape, while the Ring Nebula appears as a ring or donut shape due to its orientation.

The Stingray Nebula (Hen 3-1357) is a planetary nebula. (The youngest known).
The Cat's Eye Nebula is primarily made up of gas and dust, with elements such as hydrogen, helium, and traces of heavier elements like oxygen and nitrogen. The colors seen in the nebula are due to the emission and reflection of light by these different elements and compounds.
