Is a nebula held together by gravity?

Is a nebula held together by gravity?

The gas and dust that make up nebulas are made of matter. The matter of a nebula is held together by the force of gravity. In most nebulas, there is a lot of space between the particles. In fact, nebulas are less dense than air!

Which force is responsible for pulling the nebula together?

Solar system formed about 4.6 billion year ago, when gravity pulled together low-density cloud of interstellar gas and dust (called a nebula)(movie).

What does a nebula do?

A nebula is an enormous cloud of dust and gas occupying the space between stars and acting as a nursery for new stars. The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases.

Is a force that causes a nebula to condense?

According to the nebula hypothesis, the Solar System began as a nebula, an area in the Milky Way Galaxy that was a swirling concentration of cold gas and dust. Due to some perturbation, possibly from a nearby supernova, this cloud of gas and dust began to condense, or pull together under the force of its own gravity.

Does gravity cause a nebula to become denser at the center?

Once a star forms, it never changes. _____ 6. Gravity causes a nebula to become denser at the center. A larger star remains on the main sequence longer than a smaller star.

What is the difference between nebula and supernova?

A planetary nebula is the death marker for a low mass star. A supernova is the massive explosion that marks the destruction of a more massive star.

How are planets held together in a Nebula?

Created by scoobydoo02 Terms in this set (42) the inward force of gravity and the outward force of pressure. A nebula is held together by the balance of planetesimals formed. After the solar nebula collapsed, it’s center became very hot and planetesimals collided and combined.

How does gravity affect the shape of a Nebula?

The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.

What is a nebula in space?

A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form.

What makes up the dust in a Nebula?

Those tiny dots are newly-formed stars! Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.
