What is a Giant Molecular Cloud? Well, first off, a molecular cloud is basically a cloud up in the space, and is composed mainly of molecular hydrogen and helium. And a Giant Molecular Cloud is a molecular cloud that is a hundred times the mass of our sun. It’s like about 100,000 suns can fit […]

The Milky Way is not the only galaxy existing in the vast universe. In recent years, more galaxies have been discovered. Our Solar System can be found on the Milky Way galaxy. The Milky Way galaxy is part of a group of about 30 to 35 galaxies in one neighbourhood and are collectively called as
Charles Wolf and Georges Rayet discovered three stars with emission bands in 1867 using a 40cm Foucault telescope at the Paris Observatory. Stars absorb energy at different frequencies but stars that emit gas that include a sequence of helium and nitrogen or another sequence of helium, oxygen and carbon, were something unusual. These stars were

A galaxy has plenty of stars, planetary bits and pieces, gas, dust and dark matter. Galaxies have millions or even billions of stars. The Sun is a part of
Photo by: Zedh Creative Commons The small field found at the wide range of frequencies of electromagnetic radiation is called visible light. It can be discerned by the naked eye and has wavelengths measured to be from 780 nanometers to 390 nanometers. Each wavelength has a particular color and when that specific wavelength hits one’s
Gamma ray is a electromagnetic radiation with a very short wavelength. It means, it is of high frequency. Gamma radiation is produced by interactions of sub atomic particles like fusion, fission, radioactive decay and electron-positron annihilation. Gamma rays can create great damage to living tissues since it is a type of ionizing radiation. You should
A TNO or Trans Neptunian object is any minor planet orbiting the sun in our solar system beyond Neptune, or at a distance which is more than Neptune’s (on average). Known divisions of bodies beyond Neptune which are still part of the solar system are the Kuiper belt, the scattered disk and the Oort cloud.

Technically, thermal radiation is the heat emitted by anything that is not at absolute zero; absolute zero being the coldest possible temperature where all activity at molecular level stops (also called zero K or roughly -273 degrees C and -460 degrees F). Examples of thermal radiation are sunlight and the light from an incandescent bulb.
The term singularity in science is defined as the point in space where some properties of the said point in space is infinite. There are many occurrences in space that has the capacity of singularity. One classic example of this concept is the black hole. A black hole is the result of a dead star
General relativity is what Albert Einstein theorized in 1916, which describes that gravitation also affects the shape of space and flow of time. It proposed that the bigger the matter, the more it causes the space to curve.
