What is the difference between a nebula and a protostar?
A nebula is a vast cloud of gas and dust in space, while a protostar is a dense region within a nebula where gravity causes material to come together and heat up, eventually leading to the formation of a star. In essence, a protostar is a stage in the formation process of a star within a nebula.
Nebular hypothesis of the formation of the earth?
The nebular hypothesis proposes that the solar system formed from a giant cloud of gas and dust known as a solar nebula. Gravity caused the nebula to collapse, forming a protostar at its center. As the protostar grew, debris in the surrounding disk of material began to accrete into planets, including Earth. This process led to the formation of our planet and the rest of the solar system.
What is the horse head nebula?
The Horsehead Nebula is a dark nebula located in the constellation Orion. It is a cloud of dust and gas that is backlit by a nearby bright star, giving it the distinctive shape that resembles the head of a horse. The nebula is a popular target for astrophotography due to its striking appearance.
Did planet earth form from drops of water or grains of dust?
Planet Earth formed from dust and gas in the solar nebula, not from drops of water. The dust and gas in the nebula gradually came together through a process called accretion, leading to the formation of larger and larger bodies that eventually became planets.
Where is Orion nebula located?
The Orion Nebula is located in the Milky Way Galaxy, within the Orion constellation, specifically in the Sword of Orion. It is easily visible to the naked eye and is one of the brightest nebulae in the night sky.
What is it called when the nebula begins collapsing and turning into a small spinning cloud?
This stage is called protostar formation. As the nebula collapses due to gravity, it begins to spin faster and forms a hot, dense core known as a protostar. This marks the beginning of the process that will eventually lead to the formation of a new star.
Another name for the interstellar matter that will eventually form a star is?
protostar or nebula
What is considered the center of the Orion nebula?
the protostar
What do nebulas form?
The nebula forms into a protostar.
What is most likely to be found in a nebula?
a protostar
What come after a nebula?
After a nebula, the next stage in the life cycle of a star is usually a protostar, where gravity causes the gas and dust within the nebula to begin collapsing and forming a dense core. Following this stage, the protostar may evolve into a main sequence star, where nuclear fusion begins in its core and it enters a stable period of energy production.

What stage comes after nebula in the star stage?
The stage that comes after the nebula in the star's life cycle is the protostar stage. During this stage, gravity causes the gas and dust within the nebula to clump together and heat up, eventually forming a dense, hot core. This marks the beginning of nuclear fusion within the protostar.
Was the earth formed from a protostar?
No, the Earth formed from gas and dust in the solar nebula that surrounded the young Sun. The protostar is the early stage of a star's formation, while the Earth's formation was part of the process that created the entire solar system.
When does a star form a nebula?
A star forms within a nebula when a region of gas and dust in space begins to collapse under gravity. As the material condenses, it heats up and forms a protostar at the center of the nebula. Over time, this protostar gathers more material and undergoes nuclear fusion to become a fully-fledged star.
What is the first stage of star creation?
The first stage of star creation is when a cloud of gas and dust called a nebula begins to contract under the influence of gravity. As the nebula contracts, it heats up and eventually reaches a temperature and density where nuclear fusion reactions can begin, leading to the formation of a protostar.
What begins the process of the solar system formation Apex?
What begins the process of solar system formation? Gas and dust in a nebula is disturbed by an outside force. Apex
