Which is bigger galaxy cluster or nebula?

By nebulae, if you mean the planetary nebulae or supernova nebulae, then Globular clusters are bigger than nebulae.

What is the difference between a galaxy and a cluster?

A galaxy is a very large collection of stars. Many are organized in bars and spiral shapes, though not all are. A galaxy cluster is a small grouping of galaxies that are gravitationally bound together.

What is the difference between nebulae and galaxies?

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. Nebulae are one of the many things that galaxies are made of, along with stars, black holes, cosmic dust, dark matter and much more.

What is the difference between a galactic cluster and a nebula?

A nebula is a cloud of gas and dust, mainly hydrogen. Nebulae are often star forming regions where new stars are born. Star clusters are collections of stars. Globular clusters are between 10 and 30 light years across which typically contain between 10,000 and several million stars.

What are clusters of galaxies called?

Clusters of galaxies, and clusters of clusters of galaxies, called superclusters, make up the structures in the geography of the universe. Galaxies are titanic swarms of tens of millions to trillions of stars. Between the stars, there can be vast interstellar clouds of gas and dust.

Why are galaxies clustered?

Astronomers think that galaxy clusters form as clumps of dark matter and their associated galaxies are pulled together by gravity to form groups of dozens of galaxies, which in turn merge to form clusters of hundreds, even thousands of galaxies. The gas in galaxy clusters is heated as the cluster is formed.

What is the difference between Nebula and supernova?

A nebula is an enormous cloud of gasses and dust made visible by the light of nearby stars or stars formed within it. A supernova is the extreme release of energy caused when nuclear fusion stops within the Core of a large star and gravity overcomes the diminishing internal pressure of radiation.

Is a galaxy cluster bigger than a galaxy?

When comparing the two, a typical globular cluster might contain a mass of 100,000 Suns, whereas the Milky Way has nearly 1 trillion solar masses. In other words, the Milky Way Galaxy contains 10 million times more mass than a typical globular cluster.

What is the difference between galaxies and stars?

To distinguish galaxies from stars, you can use the spectrum. Roughly, stars have a black-body like spectrum with features depending on the absorption and emission on the line of sight and in the chromosphere of the star. Galaxies on the other hand of a spectrum that is the composite of tons of stars.
