Two primary elements found in a nebula are hydrogen and helium. Hydrogen, the most abundant element in the universe, constitutes a significant portion of the gas within nebulae, while helium is formed as a byproduct of nuclear fusion processes in stars. These elements play crucial roles in the formation of stars and planetary systems as they collapse and coalesce under gravity.
Hydrogen and Helium
The names of two nebulae are the Orion Nebula and the Crab Nebula.

Two well-known nebulae are the Orion Nebula (Messier 42) and the Crab Nebula (Messier 1). The Orion Nebula is a diffuse cloud in the constellation Orion, visible to the naked eye, while the Crab Nebula is a remnant of a supernova explosion observed in the year 1054.
Gravitational force pulls gas and dust particles together to form a nebula, while the outward pressure from gas particles pushing against each other (thermal pressure) prevents the nebula from collapsing under gravity. These two forces work together to stabilize a nebula.
Roughly 98% of the solar nebula's mass consisted of hydrogen and helium gases. These two elements are the most abundant in the universe and are the primary components of stars like our sun.

Pattern and rhythm are two design elements found in the American flag.
Metals and non-metals are the two primary categories of elements.
There is no such thing as a nebula star.

Eta Carinae is a massive binary star system located in the Carina constellation. It consists of two massive stars, with the primary star being a blue hypergiant and the companion likely a massive hot star. These stars are surrounded by a dense nebula of gas and dust.
Hydrogen and helium were the two primary gases present during the formation of our solar system. These gases dominated the early solar nebula from which the Sun and the planets eventually condensed.
There are two types of elements. They are carbon and hydrogen
