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.

What is a nebula a mixture of?
A nebula is a cloud of gas and dust in interstellar space. Every nebula contains hydrogen and helium, plus a mixture of other gases. Our galaxy has many nebulae, and astronomers have found these clouds in other galaxies, as well.
Is nebula made of ice?
Our Solar System as we know it today formed out of a primordial disk of gas and dust called the Solar Nebula. Thus, the water ice is thought to form when a clump of gas close to the star migrates outwards and cools. The water ice is expected to condense out at temperatures of ~120-180 K.
How are stars formed in a nebula?
Star Forming Nebula Stars are born in clouds of gas and dust. These knots contain sufficient mass that the gas and dust can begin to collapse from gravitational attraction. As it collapses, pressure from gravity causes the material at the center to heat up, creating a protostar.
Is Earth in a nebula?
The Earth was formed from the nebula that produced the Solar System. It is almost universally accepted that the Sun, the planets and their satellites, the asteroids, and the comets of the Oort ‘cloud’ grew from a cloud of gas and dust that contracted under its own gravity.
Do nebula exist in galaxies?
Nebulae are found inside galaxies, filling the space between stars or enveloping stars like a cloak. They’re made of dust and gas and can appear as either bright or dark clouds. The gas is mostly hydrogen mixed with some helium.
What is Jupiter’s main ingredient?
Jupiter is made up predominantly of hydrogen. The simple, basic gas, a prime ingredient on the sun, accounts for 90 percent of the atmosphere. Nearly 10 percent is composed of helium. A very small fraction of the atmosphere is made up of compounds such as ammonia, sulfur, methane, and water vapor.
What are Jovian planets?
Vocabulary. These are terms students may encounter while doing further research on the planets in the solar system: Jovian planets: The outer planets of our solar system: Jupiter, Saturn, Uranus, and Neptune.
What lies in between Mars and Jupiter?
Most of these objects, called planetoids or asteroids — meaning “star-like” — orbit between Mars and Jupiter in a grouping known as the Main Asteroid Belt. The Main Asteroid Belt lies more than two-and-a-half times as far as Earth does from the sun. It contains millions of asteroids, according to NASA.
What nebula is Earth in?
The closest known nebula to Earth is called the Helix Nebula.
Can you fly through nebula?
We’re not going to fly through a nebula, not in the lifetimes of anyone alive today. Possibly not ever in anyone’s lifetime. The nearest bright nebula to us is around 695 light-years away, and the Orion nebula is much farther, around 1,344 light-years away.
Is a nebula bigger than a galaxy?
Simply put, the main difference between galaxies and nebulae are an extreme difference in size, as well as their basic structure. A nebula is a cloud of dust and gas, usually tens to hundreds of light years across. A galaxy is much larger — usually thousands to hundreds of thousands of light years across.
Can a star turn into a planet?
yes! A star can turn into a planet, but this is true only for a specific category of stars called brown dwarfs.
Which is larger a galaxy or the universe?
The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!
How does a planetary nebula form?
A planetary nebula forms when a star can no longer support itself by fusion reactions in its center. The gravity from the material in the outer part of the star takes its inevitable toll on the structure of the star, and forces the inner parts to condense and heat up.
