What happens to nebula over time?

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. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity.

What does nebula eventually become?

Nebulae are often star-forming regions, such as in the “Pillars of Creation” in the Eagle Nebula. In these regions, the formations of gas, dust, and other materials “clump” together to form denser regions, which attract further matter, and eventually will become dense enough to form stars.

How long does it take a nebula to collapse?

Explanation: For a star the size of the sun, it takes ~10 million years for the nebula to collapse. For bigger stars, it takes a shorter amount of time; as short as 100,000 years. For smaller stars, it can take far more than 10 million years.

How long does a nebula last in general terms?

So that’s it: Nebulas turn into stars, and stars turn into nebulas. It’s a cycle that has persisted for over 13 billion years, starting when the first nebula scrunched down into a star. And it will continue to last for trillions more.

Do nebulas last forever?

They are clouds of gas — the remnants of stars comparable to the sun that have burned all their hydrogen fuel and contracted to become white dwarfs. Because they are expanding at high speeds, these clouds don’t last long — at least in terms of stellar and galactic time periods.

How does a nebula move?

The newly-born stars release energy and radiation. The moving particles move and push the gas and dust surrounding it in the nebula. The cloud and gas moving cause the nebula to shift and change its shape overall.

How long do white dwarfs last?

Eventually—over tens or even hundreds of billions of years—a white dwarf cools until it becomes a black dwarf, which emits no energy. Because the universe’s oldest stars are only 10 billion to 20 billion years old there are no known black dwarfs—yet.
