Nova
Explosions in space are called Nova. This term is defined as the rapid increase and the eventual explosion of a star. The word has Latin origins and means “new star”.
Galaxy
Nebula
The word “nebula” comes from Latin which means “cloud.” It is apt, because nebulae (the plural of nebula) look like clouds of gases. Nebulae are made up mostly of hydrogen and helium gases, plus plasma and dust. These clouds are believed to be the birthplace of stars.
Photosphere
Light emitted by astronomical bodies is one of the major clues found in the vast universe. With light, astronomers and astrophysicists can see beyond the stunning brilliance of the celestial bodies found in our galaxy. The Sun is probably one of the most brilliant celestial bodies that we have seen and the nearest to Earth.
Protostar
Thanks to Viktor Ambartsumian, a Soviet physicist, who proposed the existence of a protostar. Because of that much is known today about how stars are formed, dispelling unfounded beliefs of their origin.
Radio Galaxy
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
Short Period Comet
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

Proxima Centauri
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.
Planetary Nebula
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.
Protoplanetary Disk
In astronomy, the term protoplanetary disk refers to the circumstellar disk of space matter, composing of space dust, different types of gas, specifically the types of nitrogen, hydrogen or other elemental gas. It is said that this type of astronomical marvel is the basis or essential structure for forming planetary systems, and eventually galaxies.

Periodic Comets
Comets are spectacular sights in the night sky. Despite their burning appearance, comets are actually made of ice, small rock particles, and dust. But comets, unlike meteors, are rarely seen in the night sky. Comets have different orbital periods, which can range from several years to hundreds of thousand years. Comets are classified according to
