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..
What causes a star to die?
Stars die because they exhaust their nuclear fuel. … Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’.
Where are the pillars of creation?
Pillars of Creation is a photograph taken by the Hubble Space Telescope of elephant trunks of interstellar gas and dust in the Eagle Nebula, specifically the Serpens constellation, some 6,500–7,000 light years from Earth.
How long can a nebula live?
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.

Are nebulae dangerous?
There’s nothing especially dangerous about the nebula specifically, deep space will kill your crew in time, if their ship is damaged. They need to escape this nebula to get to somewhere they can do long-term repairs on their ship.
How can I see a nebula?
Many nebulae are visible from Earth in a small and cheap telescope, and even to the naked eye (if you are standing in a sufficiently dark place)….2 AnswersGalaxies, e.g. the Andromeda Galaxy.Stellar clusters, e.g. the Eagle Nebula.Planetary nebulae, e.g. the Eskimo Nebula.Supernova remnants, e.g. the Crab Nebula.
Can you live in a nebula?
Possibly, but probably not. It is not known when life formed on Earth, but Earth was once part of a nebula, and it now has life. … Solar nebulae like the one that formed our solar system are essentially cleared by the gravity of the sun and planets within 10–100 million years.
Which nebula is Earth in?
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 does a nebula look like to the human eye?
In the telescope, it is a green-to-gray cloudy patch. It’s just too dim for you to see in color. There’s not enough energy to excite the cells in your retina that are responsible for color vision. If your eyes were sensitive enough, you’d see it in shades of purple and red.
What would happen if you went into a nebula?
Traveling through one would be almost indistinguishable from traveling anywhere else in space. You may not even notice it with unaided eyes. On a dark night, you can see the Orion Nebula as a very faint patch of gray light. Amazingly, getting closer to the nebula would not increase its brightness per square arc second.
How do Nebula die?
The birthplace of a star is a huge, cold cloud of gas and dust, nebulae/nebulas. These clouds begin to shrink, a result of their own gravity. As a cloud begins to shrink it gets smaller and the cloud breaks up into clumps. … When a star can no longer maintain this balance, it dies.
Is Nebula a hero or villain?
Nebula is a major character in the Marvel Cinematic Universe. She served as the secondary antagonist of Guardians of the Galaxy, as the anti-heroic tritagonist of Guardians of the Galaxy Vol. 2, and as one of the tritagonists of Avengers: Infinity War.
Is Earth inside a nebula?
The planet Earth is not part of any particularly named Nebula . Earth is part of the Solar System which is part of our home galaxy, the so-called “Milky Way”, which is part of the so-called Local Group , a collection of more than 50 other galaxies in the “neighborhood” of our own galaxy.
What causes Nebula?
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. … For this reason, some nebulae are called “star nurseries.”
What is the difference between a star and a nebula?
As nouns the difference between star and nebula 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).
Is a nebula bigger than a galaxy?
Nebula is a cloud of interstellar dust, while galaxy is a huge collection of stars. Size of a galaxy is much larger than size of a nebula. … Life of several stars is connected to life of a galaxy while life of only one star is associated with a nebula. Galaxies can be found in clusters in space.
Do nebulas move?
Do nebulae move? They do move, but you don’t notice it because they are astoundingly, mindbogglingly HUGE, and even fast-moving parts take months and years to show even slight changes.
