What are in nebulae?
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 is the most beautiful nebula?
Ten of the Most Unusual Stellar Nebulae“The Hand of God:”The Egg Nebula. … V838 Monoceros. … Calabash Nebula. … The Necklace Nebula: … Barnard 68. … The Waterfall Nebula. … NGC 2438. This abnormal-looking celestial region is NGC 2438, a planetary nebula that can be found about 3,000 light-years from Earth (in the constellation of Puppis). … More items…•
What is a dead star called?
A black dwarf is a theoretical stellar remnant, specifically a white dwarf that has cooled sufficiently that it no longer emits significant heat or light.
What is a dying star called?
Some types of stars expire with titanic explosions, called supernovae. When a star like the Sun dies, it casts its outer layers into space, leaving its hot, dense core to cool over the eons.
What is a average star?
An average star, or intermediate-mass star, is a star with an initial mass of 0.5 to 8 times that of Earth’s sun. … When the hydrogen in its core and outer layers fuses into helium, the star expands and cools to become a red giant star.
Why do stars 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’.
What are the 4 types of nebulae?
The four types of nebulae are: emission, reflection, dark, and planetary. Primarily the birth place of stars, nebulae are clouds of gas and dust in space. Emission nebulae and reflection nebulae are bright nebulae.
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 a nebula a dead star?
A nebula is a cloud of gas and dust in space. Some nebulae (more than one nebula) are regions where new stars are being formed, while others are the remains of dead or dying stars. Nebulae come in many different shapes and sizes.
What is the biggest star known?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.
How stars are born and die?
Stars are born when large gas clouds collapse under gravity. … When it eventually dies, it will expand to a form known as a ‘red giant’ and then all the outer layers of the Sun will gradually blow out into space leaving only a small White Dwarf star behind about the size of the Earth.
How many nebulae are there?
3,000Right now, we know of about 3,000 planetary nebulae in our galaxy, the Milky Way, out of roughly 200 billion stars. Most of them are near the center of our galaxy. They come in many shapes, but most are spherical, elliptical, or bipolar.
What is it like inside a nebula?
Nebulae are pretty only when they are hundreds of light-years away. They look thick and cloudy only because you see the structures of light-years in thickness. Once you’re close to them, their light spreads out so much that you can’t see them. You could fly your spaceship right into the nebula and never even know it.
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.
What is the biggest nebula in the universe?
Tarantula NebulaLargest Nebula: The Tarantula Nebula Both the largest known nebula and most active star-forming region in our local galactic neighborhood, the Tarantula Nebula stretches for more than 1,800 light-years at its longest span.
What is the life of a star?
A star’s life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star’s mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born.
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.
What nebula can we see?
Orion NebulaThe Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion’s Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky.
Will our Sun become a black hole?
No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf – a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.
How are nebulae named?
Named after the Latin word for “cloud”, nebulae are not only massive clouds of dust, hydrogen and helium gas, and plasma; they are also often “stellar nurseries” – i.e. the place where stars are born. And for centuries, distant galaxies were often mistaken for these massive clouds.
