What else can I help you with?
When is a star formed?
Stars form when there is a sufficient concentration of interstellar gas, to begin the process of gravitational collapse into a star.
What are the types of matter new stars can form from?
New stars form from the interstellar gas and dust; mainly hydrogen and helium.
What are interstellar gas clouds?
Interstellar gas clouds are large clouds of gas and dust located in the vast spaces between stars in a galaxy. These clouds play a crucial role in the formation of new stars and planetary systems, as they can eventually collapse under their own gravity to form protostars. Interstellar gas clouds can also contain complex molecules that are crucial for the chemistry of the universe.
Are planets older than stars?
No. Planets are formed after stars are and in most cases planets are consumed by the same star. Some stars can exist long after they have exhausted their supply of hydrogen and heavier element as red giants. Some even may last over 100 of trillions of years.
Do planets and stars form the same way?
Actually, to quite an extent, they do. Whenever enough material in interstellar space accretes together until it has an appreciable mass, and thus attracts even more material to itself, you have the beginning of either a planet or a star. A planet if it is largely solids, or an amount of gas insufficient to make it a star, or a star if it is mostly hydrogen, and has enough of it to cause nuclear fusion at the center.

Stars form from?
Interstellar gas and dust.
Interstellar gas clouds may collapse to form stars if they?
if they are massive enough and have sufficient gravitational force to overcome pressure forces and begin the process of nuclear fusion, which powers stars. This collapse is triggered by disturbances such as shock waves from supernovae or gravitational interactions with other clouds.
How do stars form in the universe?
Stars form in the universe through the process of gravitational collapse of gas and dust within interstellar clouds. As the cloud collapses, it heats up and forms a protostar, which eventually ignites nuclear fusion in its core, becoming a full-fledged star.
What is the birthplace of stars called?
The birthplace of stars is called a stellar nursery or star-forming region. These regions are often found within interstellar clouds of gas and dust where gravitational forces cause these materials to collapse and form new stars.
What can gas and dust in interstellar nebulae form?
Gas and dust in interstellar nebulae can form stars and planetary systems through a process called stellar formation. As gravity causes the gas and dust to collapse and condense, they heat up and eventually ignite nuclear fusion, leading to the formation of a star. Planets and other celestial bodies can then form from the leftover material in the nebula.
What are the types of matter new stars can form from?
New stars form from the interstellar gas and dust; mainly hydrogen and helium.
Did the sun form outside the rotating interstelear cloud?
We believe that stars form at the CENTERS of rotating interstellar gas clouds.
Did gravity form stars?
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
How are dark nebulae formed?
Dark nebulae are formed when dense interstellar clouds of gas and dust block the light from background stars, creating a visible dark patch against the bright emission nebulae behind them. Gravitational forces can cause these clouds to collapse and form new stars within them over time.
What are interstellar gas clouds?
Interstellar gas clouds are large clouds of gas and dust located in the vast spaces between stars in a galaxy. These clouds play a crucial role in the formation of new stars and planetary systems, as they can eventually collapse under their own gravity to form protostars. Interstellar gas clouds can also contain complex molecules that are crucial for the chemistry of the universe.
What caused the interstellar cloud to collapse?
Nebulae are massive collections of gas and dust that usually are very cool around 5-30 kelvin. These nebulae are the remains of dead stars that have long died and have had enough time to cool themselves from the original energy release of the nova or supernova that created them. As the nebula cools the particles begin to slow down and once cool enough gravity will begin to collapse the nebulae and form what is known as a protostar. This is the birth of stars, and is essential for star formation.
