Components of the Universe
The components of the universe are Stars, Nebulae, Clusters, Galaxies, Pulsars, Quasars, Black Holes, and Dark Matter.
Nebulae
Nebula is a cloud of gas and dust found in space. They are very pretty, and described as some of the most gorgeous things in the entire universe. They are also huge in size, while even being the building blocks for galaxies. Nebulae are classified into 5 categories: Emission, Reflection, Dark, Planetary, and Supernova. Nebulae are usually reds, blues, and greens.
Stars
Without stars, there would be no life. Stars don't actually twinkle; it's just a wavered image. They provide light and energy that fuels the universe. There are six different types of stars: Main Sequence, Red Giants, White Dwarfs, Brown Dwarfs, Variable Stars, and Binary Stars. Stars go through a circle of life. A star is like a a large nuclear furnace.
Black Holes
If the sun becomes a black hole, the planets would still orbit around "Sun" and daily life would still go on.
If you entered a black hole, you would be stretched out like spaghetti. They are formed from the cores of super massive stars. Their escape velocity is faster than the speed of light. There is lots of mass, it's very dense. They are situated at the center of a galaxy; they are formed from super massive stars.

Dark Matter
Dark Matter is something though not visible to the eye, there is tons of evidence out there that supports it, starting with the Big Bang itself. A while after the Big Bang took place, stars, galaxies, and the rest of the universe as we know it cooled down and took place. Though there is tons and tons of matter out there (so much that it is literally uncountable), much seems to be missing. This is what we know as Dark Matter: scientists say that what we see of the universe, is only 10% of the matter out there in the universe, so 90% is missing. They link this missing 90% as Dark Matter. As gravity holds the universe together, Dark Matter has its own gravitational effects on objects. For example, galaxies have found to rotate faster than they should be.
Quasars
Quasars were discovered in the 1960s. As of now, quasars are the brightest and most distant objects in the universe. At first, they were thought to be stars, but it was soon discovered that quasars were/are not stars; they were just like a star-like object. They are extremely intriguing objects, but scientists have still not figured out what they are. They are believed to produce 10 times to 100 times more energy than our entire galaxy. Quasars are not yet fully defined; but, the most educated and likely guess is that quasars are produced by massive black holes. They travel at 80% of the speed of light. We always see them at the end of the red spectrum because they are so far away.
Pulsars
Pulsars are rapidly spinning neutron stars. These stars come from the leftovers or what is left behind after a supernova explosion. Pulsars have an extremely large magnetic field, and it is almost one trillion times stronger than Earth's magnetic field. They can sometimes emit radio-waves, and gamma rays, depending on the size.
Galaxies
Galaxies are the large groupings our stars, dust, and gas that are grouped together by gravity. Galaxies usually contain: stars, planets, moons, comets, asteroids, nebulae, dust, neutron stars, and black holes. Our own galaxy is the Milky Way galaxies. Galaxies are grouped together by shape: Spiral, Elliptical, Irregular. The Milky Way galaxy is always in motion. There are billions of galaxies; the Milky Way is in a cluster with 40 other galaxies. There are about 100 billion stars in our galaxy.
Clusters
There are 2 types of clusters:
They are grouping of stars, but they are also groupings of galaxies.
