What 2 forces balance each other to keep of nebula dust and gas from collapsing or flying apart?
Gravitational force pulls the dust and gas inward, trying to collapse the nebula, while outward gas pressure from nuclear fusion reactions occurring in the core of the nebula pushes back, preventing the collapse. These two forces are in equilibrium, keeping the nebula stable.
Did gravity form stars?
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
Where do stars begin their lives?
Stars begin their lives as clouds of gas and dust called nebulae. Within these nebulae, gravity causes the gas and dust to collapse and heat up, eventually leading to the ignition of nuclear fusion in the core, which marks the birth of a star.
What is a large cloud of gas and dust from which stars are formed?
A large cloud of gas and dust from which stars are formed is called a nebula. Within a nebula, gravity causes the gas and dust to come together, forming clumps that eventually collapse to create new stars. Nebulae are often seen as glowing or dark patches in the night sky.
Large clouds of gas and dust are called?
Nebulae. These nebulae are often regions in space where new stars are forming due to the gravitational collapse of the gas and dust. They come in various shapes and sizes, and are some of the most beautiful and mesmerizing objects in the universe.
What is Gas and dust sticks to itself and collapses?
Gravitational instability theory....
What is the gravatational instability theory?
gas and dust sticks to itself and collapses
What theory is gas and dust sticks to its self and collapses?
The theory that describes gas and dust sticking together and collapsing is known as the nebular hypothesis. This theory suggests that interstellar gas and dust gradually coalesce due to gravitational attraction, forming clumps that eventually become denser and collapse under their own gravity, leading to the formation of stars and planetary systems. As the material collapses, it can heat up and form a protostar, while surrounding material may form a rotating disk from which planets can emerge.
A large cloud of dust and gas that becomes a star?
This process is called stellar nucleosynthesis. It occurs when gravity causes a cloud of dust and gas to collapse in on itself, leading to high temperatures and pressures at the core. This triggers nuclear fusion reactions that convert hydrogen into heavier elements and release energy, ultimately forming a new star.
What 2 forces balance each other to keep of nebula dust and gas from collapsing or flying apart?
Gravitational force pulls the dust and gas inward, trying to collapse the nebula, while outward gas pressure from nuclear fusion reactions occurring in the core of the nebula pushes back, preventing the collapse. These two forces are in equilibrium, keeping the nebula stable.
Did gravity form stars?
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
How were stars formed in the clouds?
The prevailing view is that stars form from the gravitational collapse of immense clouds of gas and dust in outer space.
Where do stars begin their lives?
Stars begin their lives as clouds of gas and dust called nebulae. Within these nebulae, gravity causes the gas and dust to collapse and heat up, eventually leading to the ignition of nuclear fusion in the core, which marks the birth of a star.

Are stars born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Yes, that's correct! Stars are born when gravity causes gas and dust in a molecular cloud to collapse under their own weight. This collapse creates high pressures and temperatures in the core of the forming star, eventually igniting nuclear fusion and creating a stable star.
What pulled the dust and gas of the solar system together?
The dust and gas of the solar system were pulled together primarily by gravity. Initially, a rotating cloud of gas and dust, known as the solar nebula, began to collapse under its own gravitational attraction. As it contracted, it spun faster and flattened into a disk, leading to the formation of the Sun at the center and planets from the remaining material. This process was influenced by various factors, including shock waves from nearby supernovae that may have triggered the collapse.
Is dust made from gas?
Dust comes from a bunch of things, including dead skin and dust mites, but none of those things are gasses. They are solids, as is dust itself, just very small particles.
