A radiometer is a device used for measuring different types of electromagnetic radiation or energy that exhibit wave-like properties. All objects that have a temperature beyond absolute zero are able to radiate this type of energy into the space surrounding them. This is also true for objects found in space such as stars and even […]
A groundbreaking development in the field of science occurred in the early parts of the 20th century when Albert Einstein introduced the theory of relativity to a world that mostly thought that everything in the universe – space and time – are fixed into place.
A regolith is a collective term referring to the blanket of powdery materials that cover the surface of several celestial bodies such as the earth, moon, and asteroids among many others. This blanket has a powdery appearance and texture because it is composed of fine debris such as soil, shattered rock, dust, and other small
A refracting telescope is one of the earliest tools used by astronomers from way back to study outer space and distant objects. It is one of the two kinds of optical telescopes and uses a lens as the light gathering part or the objective as opposed to a mirror that is commonly used as the

Polarization refers to that property of electromagnetic waves (like light and gravity) that characterizes the orientation of their movement to and from space. Electromagnetic waves possess a vector or three-dimensional nature which results in polarization. In astronomy, great importance is placed on studying polarized electromagnetic radiations from outer space.

The concept of proper motion is related to the field of astronomy. This is the concept or principle regarding the movement of the planets or celestial bodies. The principle states that a certain celestial body, whether it is a planet or sun, changes its angular position over time, in reference to the mass center of
Prominence refers to the sun sending out tongues of fire that reaches a great distance. It is usually called solar prominence. It is defined as a large and bright extension from the sun. It extends from the sun’s surface, usually in the shape of a loop. It is found that a prominence is usually starting
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.
When you hear the term radio wave, you automatically think of broadcasting, mobile communications, and navigation systems. This is a limited perception referring to the lot of artificially-produced radio waves. Naturally-occurring radio waves, on the other hand, are produced by astronomical objects and lightning.
The term radio telescope can be quite misleading since when you think of a telescope, you think of a device used for viewing objects; while you attribute the word radio with hearing. However, all the discoveries in radio astronomy that people know of today could not have been possible without the trusty radio telescope.
