Dwarves are aspects of the stars that are understood through their evolutionary life. There are several types of dwarves for instance brown dwarves and white dwarves. In the first instance, the word nebulae were used to refer to extended astronomical objects except comets and planets. It originates from a Greek word that refers to cloud. Astronomers named galaxies nebulae because of their blurry appearance. Currently the word nebula is used to refer to extended objects that consist of gas and dust.Electromagnetic spectrum is a word used to refer to a variety of potential frequencies of electromagnetic radiation. This paper looks at dwarves and nebulae in color and shape segments of the electromagnetic spectrum.The concept of dwarf can be understood by studying galaxies. Most galaxies seem to be a dwarf. They are usually small when they are compared with other galactic structures.  They contain a few billion stars, as opposed to other galactic structures. Most of the dwarf galaxies move around a bigger galaxy.  Dwarf galaxies are grouped like elliptical, irregular or spiral. Small dwarf elliptical are called dwarf spherical galaxies because they resemble large elliptical.  Dwarf galaxies rare approximated to be about ten million masses of solar. Galaxies have been understood to be formed by dark matter, and their small size indicates a form of dark, warm matter that is not able to perform gravitational coalescence in small scale (Jones, 80).Nebulas come in different shapes and sizes and many formations. In certain forms of nebula, stars are formed from large clouds of gas and dust. After stars have formed inside the cloud, the light they produce lightens the clouds helping us to see them.

White dwarfs are formed after the outer layer of the star is removed. The remaining mass of the material that is left is usually too small to provide enough pressure that can maintain nuclear temperature in the hydrogen-burning shell. Thus, there remaining star contracts faster to form a white dwarf. A white dwarf is a star that is the same as the sun  in  its mass form but is similar to the earth in diameter such as that one that in seen in the planetary nebular (Bode and  Aneurin, 284). A white dwarf has one of the highest temperatures ever observed in the world. The white dwarf is the one hat is closest to the sun because it is the brightest among all the stars.Planetary nebulae and dwarves help us understand how the stars are formed and how they light up. We also get to understand their shapes and sizes by looking at nebulae and dwarves. Stars have different shapes, sizes and color that are influenced by nebulae and dwarf properties.Both dwarves and nebula are related aspects of the electromagnetic spectrum. They are related because the formation of nebulae results dwarves of different types for instance brown and white dwarves.

Planetary nebula is formed when a star dies. It is referred to as a planetary nebula because it looks like a big planet giant through a telescope. The galaxy may contain about then thousand planet nebulae.Neuron stars hold a vital place in astronomic. It is not only because they are made up of the most tremendous states of the reduced matter, but because they are, next to the white dwarfs and black holes, one of the stable configurations that star achieve at the end of stellar evolution. Neutron stars have the highest revolving rates and strongest magnetic turf among all stars. They radiate very fast, in high energy electromagnetic radiation and also in the radio band.  The ASI is dedicated to the spectral characteristics of neutron stars. Spectral studies of neutron stars aid us to know the magnetosphere discharge development of unreachable radio pulsars and the discharge procedures of accreting neutron stars. This quantity includes spectral data from the neutron stars in the widest sense, to be precise, neutrino and gravitational rays along with the electromagnetic spectrum. This volume may serve as a graduate level text as well as the broad variety of properties of neutron stars (Baidyanath, 252).Star dust can also be referred to as nebulae. This is because they are composed of gases that both create and are created by stars. The stars are composed of dense and temperatures that are very high. Nebulae are cooler and are less dense than other forms of the electromagnetic spectrum.They are made of different shapes. The appearance that they display is attributed to the energy source that supplies them with energy.  The energy is used in lighting them. In gas regions where optical spectrum can be detected, there is a lot of gas that can be detected. But, unfortunately, cannot be seen.  For nebulae to be seen, there must be something that as to make them glow (Baykal, 127).Nebulas do not glow in the same way. The manner in which they glow depends on their type, size and shape. Some nebulas glow when they take part in the formation of new stars. They are taken to be stellar nurseries that are referred to as regions. The new stars formed are more energetic thus they produce a lot of heat that in turn light up the nebulae.The dwarf and nebulae are aspects that require close attention in order to understand their functionality.  It is through the electromagnetic spectrum, where we are able to use nebulae and dwarf to understand the formation of stars and how they light up. It is also through aspects of the electromagnetic spectrum in relation to dwarves and nebulae that we understand how galaxies function and their existence.
