A nebula is a massive cloud of gas and other materials that is revolving around one focal point which is the most massive point and therefore has the strongest gravity which makes the rest of the cloud revolve around it. This eventually creates a star. Nuclear fusion on the other hand is simply the combination of two particles such as when hydrogen atoms collide to create helium (this is the most common kind of fusion in stars). Basically fusion takes two and makes one (basically, it can emit more particles too) while a nebula is a giant space cloud, the birth of stars.

What is the difference in between nebula and solar nebula?
A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
What is the difference between the Helix Nebula and the Ring Nebula?
The helix nebula is more close than the ring nebula, as well as much brighter and larger than the ring but with low surface brightness.
Why is the center of a collapsing nebula forms a star?
If enough matter comes together close enough, the collapse itself will generate enough heat (and pressure) for nuclear fusion. In other words, a star is created.
Are stars born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Yes, stars are born when gravity pulls gas and dust together from a nebula.
What happens after a nebula contracts and its temperature increases to 10million K?
That is hot enough to ignite hydrogen fusion, so the nebula becomes a star (possibly with planets).
What is the difference between a nebula and a crab nebula?
The Crab Nebula is a nebula.
Are stars nuclear energy?
Stars produce nuclear energy by fusion Stars form when contracting dust in a planetary nebula contract and get so hot that nuclear fusion occurs. It explodes, forming a porotostar. Nuclear fusion of hydrogen atoms combining to form helium atoms is what keeps the star glowing.
What is the difference in between nebula and solar nebula?
A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
What is the difference between a emission nebula and a reflection nebula?
Emission nebula glow and reflection nebula reflect the light form other stars
What is the different between a galaxy and a nebula?
it is plop of a difference
What describes a major role of gravity in star formation?
Gravity compresses gases at the center of a solar nebula until temperatures are high enough for nuclear fusion to occur
What is the difference between a planetery nebula and a nebula?
A cloud in outer space consisting of gas or dust and planetry nebula is one of the types also called ring nebula or A planetary nebula is an emission nebula consisting of a glowing shell of gas
What is the difference between the Helix Nebula and the Ring Nebula?
The helix nebula is more close than the ring nebula, as well as much brighter and larger than the ring but with low surface brightness.
Whats the difference between a nebulae and a nebula?
"Nebula" is a astronomical term for a cloud of gas and dust. "Nebulae" is the plural of "Nebula" and refers to more than one such cloud.
What set off ongoing Nuclear Fusion in the sun?
Heat, derived from gravitational energy. The gravitational collapse of the original nebula of gas and dust produced very high temperatures and a "protosun". Eventually the protosun became a star (our Sun) when the nuclear fusion reactions began at temperatures of millions of degrees Celsius.
Is friction responsible for the formation of a star?
No. A star forms when gravity causes a nebula to collapse. As the gas compresses it heats up. eventually, the heat and pressure ignite nuclear fusion.
How did gravity play a role in the creation of your sun?
Gravity pulled pieces from the Solar Nebula together causing the hydrogen and helium atoms to start nuclear fusion which eventually created the sun.
