In the simplest sense, a radio galaxy, as the name connotes, is a galaxy that serves as a strong source of electromagnetic radiation or radio waves. The discovery of radio galaxies provides proof of the ability of the universe to expand contrary to the steady state it was once perceived to be. One of the […]
A short-period comet is a comet that has a relatively short lifespan for any observation can be made for comparative studies. That period is known to be shorter than two hundred years. Recently, short-period comets have been subdivided into the Jupiter-type comets, like that of Temple 2 and Encke, which typically have periods of just

Organization in science is a must. When trying to classify, scientists call this the study of classification or taxonomy. Well, in terms of astronomy, there is also organization. And one of these classifications is called the spectral class. Spectral class or spectral classification is the manner of organization in astronomy that deals with classifying stars

A shock wave is a type of disturbance propagating outward. Just like any ordinary wave, it carries with it energy that spreads out through solid, liquid, or gas mediums. In some cases, shockwaves can also spread out without those mediums, but through specific fields like the electromagnetic field.
The invention of technological gadgets has made the universe seemingly small. Today, however, people have learned that the sun is just a star and is seen as big because of its proximity to Earth, which is about 150 million km away.
The term Precession is usually associated with the fields of Physics and Astronomy. It is usually defined as the change in orientation of the rotational axis of a certain object or celestial body. Also, this term in astronomy refers to the many slow, continuous and gravity dependent changes in direction of a body’s orbital conditions,
The primary mirror is defined as the light gathering, or refracting surface of a telescope. It is also called as the telescope’s objective. In a reflecting telescope, it either uses a single or a pair of curved mirrors to reflect light in order to form an image based on the location where the said telescope
The prime meridian is considered as the middle point of earth. It is also commonly known as the Greenwich Meridian and is a component that forms the International Date Line, which then divides the Western and Eastern Hemispheres of the Earth.
In science, there will always be the term prism, especially when the field of optics is involved. A prism is an optical equipment with a transparent color, a flat, triangular shaped, and polished surface, which refracts light.
A planetary nebula is not a planet, although its name often gives that initial impression. It is actually the accumulation of gas and plasma given off by a star that is about to bade farewell to the universe. They are so named because their appearance through a small optical telescope closely resembles a giant planet.
