The Rotation period is the time required for a body to rotate around its axis. The lower the period means the greater rotation boost it has. This differs greatly from the planet’s solar day, which would include an extra fractional rotation which is needed to furnish the portion of the planet’s orbital period during one […]
A Rotation is the circular movement of an object around a point. It is the act of rotating or turning around. In astronomy, it is a phenomenon that various celestial bodies experience. Stars, planets and other celestial bodies all spin around on their axis. The rotation rate of planets in the solar system was first
What do you think of a Reusable launch vehicle (RLV)? It is a system that is capable of launching a launch vehicle to space more than once. It is different from expendable launch systems, wherein each launch vehicle is only launched only once and then discarded. Currently no true reusable launch vehicle is in use.

What is Right ascension? This is the term astronomer’s use for one of the two coordinates of a point right on the celestial sphere when using the equatorial coordinate system. The other coordinate is referred to as declination. It is said that the concept of RA has been known since the time of Hipparchus. It
There are a lot of things that has been said about our galaxy. There is no doubt that increased magnification would give you a beautiful view of celestial bodies, the Moon, the planets and details of sky objects. To see them properly, a Rich field telescope would come in handy. This is a fast focal

One of the three major macromolecules along with DNA and proteins is Ribonucleic acid (RNA). These are essential for all forms of life. RNA is made up of nucleotides, and each nucleotide consists of a nucleobase which is also known as a nitrogenous base. Nucleic acids were discovered in 1868 by Friedrich Miescher,

In the solar system most of the rotational and orbital motions are in the eastward direction. This is referred to as direct motion. Those in the opposite direction are called retrograde. There are three types of retrograde motion in astronomy. Planets, as scientists have noted move relative to the stars, moving from west to east
What are extragalactic objects, and why study them? Extragalactic objects give us a hint on what the universe really is like. Extragalactic objects are, simply put, all astronomical objects outside of the Milky Way.

Since long ago, people have determined time by looking at the skies and the astronomical events that occur. You already know that the rotation of the earth defines day and night while the revolution of the earth around the sun causes different seasons and also determines a “year”. However, with the advances in technology, scientists
Most celestial bodies can be observed as entities resembling a definite shape when the proper equipment is used. The Sun, when viewed under a solar filter resembles a great big ball without the harmful rays. Most of the stars can be viewed the same way, where it can be seen as a sphere. However, numerous
