A Brown dwarf is an object that is big in size to be considered as a planet but a bit minute to be called a star. It is thought that they form in the similar manner as the stars do. Scientists are taking into consideration the possibility that they could have come from a cloud […]

A fullerene is a molecule which mainly consists of the element carbon. It may take the shape of an empty sphere, tube or ellipsoid. Cylindrical fullerenes are also referred to as buckytubes or carbon nanotubes. On the other hand, spherical fullerenes are named as buckyballs. It was discovered by the scientists Robert Curl, Richard Smalley

A tightly packed group of stars is called a bulge. It was previously thought to be as elliptical galaxies that have group of stars around them. However, high resolution images provided by space telescopes show that bulges can be spiral galaxies. Nowadays, there are two types of bulges. The first one is the elliptical or

Cosmology is the study of the universe including its origin, structure and evolution. It is also any model that is said to represent the universe. It has undergone different stages in explaining the total complexity of the universe. Early people thought that the universe is what they immediately interacted with such as earthquakes, changes on

Cosmology is the study of the cosmos. Cosmos in a general sense refers to an orderly or harmonious inter-galactic system. During the ancient times, it means the ordered world. Nowadays, it is used as a synonym for the word universe.

The term baseline can mean two different things in the astronomical field. In general astronomy, a baseline is usually the reference point when two or more values are being measured. It is extremely helpful when interpreting astronomical data because it can ignore any variation which can muddle the true measurements of something, such as spectral

In astronomy, a crescent is a phase of an inferior planet, such as the moon wherein less than half of the visible portion is illuminated. It was originally used to denote the waxing of the moon but nowadays, it refers to either the waning or waxing shape of either the moon or a planet. The

Critical density is the value wherein the expansion rate of the universe is stopped at an infinite period of time. The equation for finding this measurement is applied in the field of cosmology.

Cryovolcanism is the activity of a cryovolcano and its associated phenomenon. A cryovolcano is a volcano that is composed of ice especially located on the moon. Cryovolcanism evidences have been found in several moons and other solar system bodies. The first evidence of a cryovolcano is found in the south pole of Triton, Neptune’s moon.

Absolute magnitude, as used in astronomy, is a measure of an object’s brightness at a distance of 10 parsec or 3.26 light years. This measure is used to easily characterize objects without giving too much information. For instance, apparent magnitude is also a measure of brightness but is dependent on the distance between the object
