Are planets formed from the same clouds of gas and dust as stars?
Yes, planets are formed from the same clouds of gas and dust as stars. These clouds are called molecular clouds, and they consist mostly of hydrogen and helium along with other elements. As the cloud collapses under gravity to form a star, leftover material congregates to form planets and other smaller bodies in the newly formed solar system.
Are larger solar systems made of gas and dust?
No. They are made mainly of stars and planets. The stars and planets came from gas and dust.
What is the bright mass of dust or gas in the sky?
It sounds like you are describing a nebula, which is a cloud of gas and dust in outer space. Nebulae can be illuminated by nearby stars, and their colors and shapes can vary depending on the composition of the gas and dust within them.
Why does a protostar rotate?
A protostar rotates due to conservation of angular momentum. As the protostar collapses from a rotating cloud of gas and dust, its rotational speed increases due to the conservation of angular momentum. This rotation plays a crucial role in shaping the final properties of the star and its surrounding planetary system.
Is Jupiter made out of dust?
Jupiter is a gas giant primarily composed of hydrogen and helium, with some trace elements like water, methane, and ammonia. It does not have a solid surface made of dust like terrestrial planets.
What is the gravatational instability theory?
gas and dust sticks to itself and collapses
What Gas and dust sticks to itself and collapse?
Gravitational instability theory
How do stars form?
Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars.
Gravitational instability theory?
Gravitational instability theory states that if a region of space contains more mass than can be supported by the internal forces (such as thermal pressure), it becomes unstable and collapses under gravity. This theory helps explain the formation of structures in the universe, such as galaxies, clusters of galaxies, and large-scale cosmic filaments. Astronomical observations support the predictions of this theory and provide evidence for the role of gravity in shaping the universe's large-scale structure.
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.
How are black dwarfs created?
A star of similar mass to the sun dies and collapses, forming a white dwarf which cools, forming a black dwarf.A mass of dust and gas too small to ignite fusion collapses, forming a brown dwarf which cools, forming a black dwarf.
What happens when massive stars collapse?
The collapses star gets squeezed by collapses gas and turns into a black hole.
Is dust a form of gas?
No - you cannot see gas particles. Dust specks are solids.
What happens when ahuge clouds of dust and gas begin to collapse?
When a large cloud of dust and gas begins to collapse due to gravity, it can undergo a process called protostar formation. As the cloud collapses, it heats up and starts spinning, eventually forming a dense core at its center. This core will continue to accumulate material and eventually become hot and dense enough to initiate nuclear fusion, becoming a star.
Can the sun create other stars?
No because the sun is a star itself. Only an object made of gas and dust called a nebula can create stars
Are planets formed from the same clouds of gas and dust as stars?
Yes, planets are formed from the same clouds of gas and dust as stars. These clouds are called molecular clouds, and they consist mostly of hydrogen and helium along with other elements. As the cloud collapses under gravity to form a star, leftover material congregates to form planets and other smaller bodies in the newly formed solar system.
What best describes the composition of a nebula as the Crab Nebula?
clouds of dust and gas
