Is a nebula a star system?

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.

Do stars live in nebulae?

Stars are born in clouds of gas and dust. One such stellar nursery is the Orion Nebula, an enormous cloud of gas and dust many light-years across. Turbulence from deep within these clouds creates high density regions called knots.

Can a solar system exist inside a nebula?

Nope. The solar wind and radiation pressure and a combination of planetary and stellar gravity would either blow away or hoover up all the gas cloud in relatively short order. That’s why there’s a fairly hard vacuum between planets in our own solar system, after all.

Is nebula a planet or star?

Though the modern interpretation is different, the old term is still used. All planetary nebulae form at the end of the life of a star of intermediate mass, about 1-8 solar masses. It is expected that the Sun will form a planetary nebula at the end of its life cycle.

What is the difference between a nebula and a star?

is that star is any small luminous dot appearing in the cloudless portion of the night sky, especially with a fixed location relative to other such dots while nebula is (astronomy) a cloud in outer space consisting of gas or dust (eg a cloud formed after a star explodes).

How is a nebula different from a star?

What is inside a nebula?

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.

Is a nebula a dead star?

Nebulae exist in the space between the stars—also known as interstellar space. It is the remnant of a dying star—possibly one like the Sun. It is approximately 700 light-years away from Earth.

What is inside of a nebula?

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.

What happens in a nebula?

Nebulae are made of dust and gases—mostly hydrogen and helium. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.

What causes a nebula to become a star?

The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star. Where are nebulae? Nebulae exist in the space between the stars—also known as interstellar space. The closest known nebula to Earth is called the Helix Nebula.

What is the atmospheric pressure around a Nebula?

Far, far away from the Earth, there is a nebula. An enormous cloud made of 78\% nitrogen, 20\% oxygen and 2\% other non-lethal materials. These gases swirl around a star, and the pressure around it is more or less 105 pascals. This star has several planets around it.

What is a nebula made out of?

Credit NASA/JPL-Caltech/University of Colorado 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.
