Igneous, from the root word ignite which means to catch fire! Did you know how an igneous rock is formed? Extremely hot molten rock from the deep recesses of the earth makes its way out and literally ignites everything it comes in contact with, once the liquid cools down, an igneous rock is formed.
In astronomy or the study of space, a lot of terms come to mind, whether it is galaxies, the universe or the cosmos come into place when this particular subject is discussed. Speaking of which, the most common term when it comes to space are the galaxies, which is defined as a bound and gravitational

The International Space Station is the collaboration of different nations working in different fields of science specifically astronomy and meteorology. It is an internationally developed facility constructed below earths orbit and can be seen with the naked eye from earth. The space station is run by different countries, mainly by the United States and Russia.

Since the discovery of Pluto in 1930, many have speculated that the dwarf planet might not be alone. The region in the Solar System which is now called the Kuiper belt had been hypothesized variedly for decades but it was only in 1992 that direct evidence of its existence was found for the first time.
A Jovian planet is a gas giant, the term is derived from Jupiter which describes the three other gas giants in the Solar System as Jupiter-like. Though the name may imply it, a gas giant is not composed only of gas. It may have a metallic or rocky core, which is believed to actually be
The planets of our solar system revolve around the sun, tracing imaginary lines are called orbits. These orbits are not perfectly round but are ellipses. Geometrically, the sun is not at the “center” of the system, but one of the foci of the ellipse. The elliptical plane that contains these orbits is the ecliptic plane.
It is approximated that a supernova (plural: supernovae) occur in the Milky Way Galaxy once every 50 years. It is a stellar explosion, or the destruction of a star at the end of its life period. The materials that were wiped out from the explosion are called ejecta (Ejecta is also used to refer to
Christian Doppler proposed in 1842 that apparent change in wavelengths of sound or light is caused by the motion of the source, the observer or the medium. Take for example an ambulance. As it approaches, the siren becomes louder and recedes as it moves away. A real shift in frequency occurs when the source of
Amateur astronomer, John Dobson, created a telescope which featured a simplified mechanical design that was easy to set up. The Dobsonian telescope is basically a reflecting telescope that uses mirrors instead of lenses. The telescope can be swiveled in any direction, just like a toy cannon with the concave mirror up front and the telescope

Astronomers rely heavily on telescopes in order to observe the night sky. However, there are certain phenomena that occur, which can make stargazing difficult. The resolution of telescopes can be limited by numerous imperfections in the lenses, and it can also be hindered by the diffraction limit.
