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.
A nebula is a vast cloud of gas and dust in space, often where stars are born. Nuclear fusion is the process by which stars generate energy by fusing hydrogen atoms into helium in their cores. In simple terms, a nebula is a region where stars form, while nuclear fusion is the process that powers stars.

Why is the center of a collapsing nebula forms a star?
When a nebula collapses due to gravitational forces, the center becomes denser and hotter. As the material in the center becomes more compact, the pressure and temperature increase, eventually triggering nuclear fusion reactions that sustain a star's energy. This marks the birth of a new star in the center of the collapsing nebula.
What happens after a nebula contracts and its temperature increases to 10million K?
After a nebula contracts and its temperature increases to 10 million K, it can start nuclear fusion in its core, becoming a protostar. The increase in temperature and pressure triggers the fusion of hydrogen atoms into helium atoms, releasing energy in the form of light and heat. The protostar will continue to evolve and eventually become a full-fledged star.
Matter from a nebula that has begun to condense?
As matter from a nebula condenses, it begins to form into clumps due to gravity. These clumps eventually evolve into protostars, as heat and pressure increase at their cores, initiating the process of nuclear fusion. This marks the beginning of a star's life cycle.
What is the difference in between nebula and solar nebula?
A nebula is a vast cloud of gas and dust in space. A solar nebula specifically refers to the cloud of gas and dust from which our solar system formed around 4.6 billion years ago.
All-stars begin their lives as a part of what?
All-stars begin their lives as a part of a molecular cloud in space. These clouds contain gas and dust that eventually collapse and form stars through the process of nuclear fusion. The intense pressure and heat at the core of the collapsing cloud triggers the fusion of hydrogen atoms into helium, leading to the birth of a new star.
Is the sun a planet or nebula?
The sun is a star, not a planet or a nebula. It is a giant ball of gas that emits light and heat due to nuclear fusion reactions happening in its core.
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 nebular fusion?
Nebular fusion is the process by which gas and dust in a nebula come together to form stars. As the material in the nebula clumps together due to gravity, it becomes denser and hotter, eventually reaching temperatures and pressures where nuclear fusion reactions can occur, leading to the birth of new stars.
What is the difference between a emission nebula and a reflection nebula?
Emission nebula glow and reflection nebula reflect the light form other stars
When the pressure and temperature of a nebula increases what is formed?
When the pressure and temperature of a nebula increase, it can lead to the formation of protostars. As gravity causes the nebula to contract and heat up, eventually nuclear fusion can begin at the core of the protostar, leading to the formation of a new star.
What is the different between a galaxy and a nebula?
it is plop of a difference
What force causes a nebula to become a star?
Gravitational attraction pulls gas and dust together in a nebula, causing it to condense and heat up. When the pressure and temperature in the core of the nebula become high enough, nuclear fusion reactions begin, initiating the process of becoming a star.
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

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.
