. It may have formed over many years. Galaxies could be formed from ten to thousands of galaxies. Galaxy clusters seem to be a group or plenty of galaxies joined together by mutual pull of gravity. There are irregular galaxy clusters and regular galaxy clusters. Irregular galaxy clusters have lesser masses and absence of a […]
To better understand what inferior conjunction is, it is important to mention first how the planets are positioned in the Solar System according to how they orbit the Sun. Here is how the planets are arranged from the closest to the Sun outwards, these are the orbits of:

If you take a look at some photos of the galaxy, like our very own Milky Way, you may see that there is a region where most of the stars lie mostly and bulge. It is known as a galactic disc. It is flat and it is where stars from the ordinary to the biggest
An astronomical interferometer is a means used by most astronomers to detect radio, sound or light waves in space or also in earth as well. It is usually an array or cluster or a group of radio antennas or satellite dishes located and placed in a specific area of land to detect and intercept any
Hypergalaxy is a system that consists of a dominant spiral galaxy that is surrounded by a cloud of smaller satellite galaxies which are often elliptical. The Milky Way in which Earth is located and the Andromeda Galaxy are examples of hypergalaxies.
Although planets are known as celestial bodies that are of greater magnitude in comparison with other forms such as asteroids and comets, there are more specific categories that depict each planet according to size. There are interstellar planets, those which are not bound to any star but orbit the galaxy; extra-solar planets, or planets outside
You have probably heard about inferior and superior planets and you might have wondered what these differences are. Being a superior planet doesn’t necessarily mean that a planet is huge compared to an inferior planet. The inferiority or the superiority of a planet refers to how near the planets’ orbits are in relation to Earth.
Although the public is familiar with microwaves as a tool to heating food, generally microwaves are minute wavelengths of electromagnetic energy that can be measured using centimeters, and are used in a broader sense. It is even believed in theory that microwaves are the cooled and calmed form of gamma radiation.
The name micron itself is a giveaway to how diminutive it is in size. Microns represent a millionth of a meter, or about 0.00003937 inches. It is part of the metric system, commonly represented by mu/µ, the Greek Letter for M. This unit of length has been used by scientists from 1879 up to 1967,
Water is an important element to sustain life. In order for a certain planet to support existence, it has to have liquid water on its surface. For this to be possible its effective surface temperature must be above the freezing point of water. A star like sun can provide energy radiation enough to maintain this
