Comet is a celestial body consisting mainly of rock, ice and gases. A comet is a frozen mass, but when it comes to the inner solar system, its particles are ionized or excited, which emits light in the process, thus giving the comet a visible coma and sometimes even a tail.
Coma Berenices is one of the traditional asterisms (group of stars) known to man since the Hellenistic period. It is located adjacent to the constellation Leo. Coma Berenices is one of the few that have been named after a famous person in history. It was named after Queen Berenice II of Egypt, who was known
In Astronomy, a Coma is known as the hazy envelope and tail of the comet nucleus. Comas are formed when the comet comes into the inner solar system where frozen gases are vaporized due to the high temperature.
Collapsar is the shortened form to describe a collapsed star and it refers formerly to a stellar-mass black hole which is a result when all of the fuel in the star namely: hydrogen and helium are used up and gravity wins because of the disequilibrium between radiation and pressure.
Coated optics include the use of special materials, commonly metals, applied into the surface of lenses or mirrors to enhance or decrease the amount of light reflected or transmitted though the surface. There are different types of coated optics suited for different uses.
Clock drives are devices used in looking at a particular star or celestial object such as the moon continuously from east to west. Because our platform, the Earth is rotating on its axis throughout the day, by using clock drives, one can follow the direction of the star or moon and keep track of it.
Cepheid variables are types of stars that illuminate or brighten and dim with regularity. Its cycle of becoming brilliant to dim and vice-versa is called the period of fluctuation lasts for more or less than fifty days. Its luminosity is related to its period of variation, which is useful in the measurement of the distances

A star that can be viewed from specific latitude on Earth that is visible for an entire night and for every night of the year is called a circumpolar star. It is also continuously in the sky throughout the day; however, it is not that visible because of the glare of the sun. This is
The chromosphere is a structure composed of warm gas that is above the visible surface of the sun and most stars, which is called photosphere. It is transparent in visible light but bright and opaque in strong lines of elements such as hydrogen, helium, calcium and oxygen.
A chondrite is a stony meteorite that had been modified because of the melting of the parent body. It was formed when certain types of small grains and dust in the early solar system were not fully formed into primitive asteroids. It contains chondrules, which are free floating, molten droplets in space which are a
