What happens when a supernova explodes? What is left is what we know as the supernova remnants or SNRs. They are extremely important to expand the understanding of the galaxy and the universe beyond. According to scientists, supernova remnants have greatly affected galactic ecology of the Milky Way. It is believed that if not for […]
The Hubble Space Telescope (HST) is considered to be the greatest space equipment ever to have been made. This special telescope gets its name from noted astronomer Edwin Hubble. Funding for the Hubble Telescope came during the 1970’s; however, it was not launched until 1990. It is a space telescope that floats hundreds of miles

Molecules are simply a group of two or more atoms held by a chemical bond. These are primitive components of matter, whether they are gases or organic substances. Just like atoms, these molecules are a higher form of building blocks, the next step before a new form of matter is completely created. In the same

Ultraviolet radiation is a form of energy that travels through space. It lies between the electromagnetic spectrum of x-ray, which is 40 nm and visible light, 400 nm. While there are many artificial sources of UV radiation, the sun is still the primary source of radiation in nature.

Sublimation refers to the process wherein solid object directly transforms into gaseous state without passing liquefaction. There are many substances that are known to undergo this process such as the element iodine. Under extreme temperatures, iodine is converted into a gaseous state without melting first. This process explains the presence of icy cap rings and
Seyfert galaxies are a particular class of galaxy where each nuclei produces spectral line emissions of highly-ionized gas. A Seyfert galaxy is always known to be spiral in nature, and is always among the most intensively studied in the field of astronomy because they are supposed to be theoretically near our own Milky Way.
To better understand what inferior conjunction is, it is important to mention first how the planets are positioned in the Solar System according to how they orbit the Sun. Here is how the planets are arranged from the closest to the Sun outwards, these are the orbits of:

Universal time is the measure of time based on the rotation of earth on its axis. Basically, it is measured from the time after midnight in the Greenwich Time zone in England. It is the time when the sun is at 180 degrees longitude. Photo by: Fonadier Creative Commons The UT is the basis of
An astronomical interferometer is a means used by most astronomers to detect radio, sound or light waves in space or also in earth as well. It is usually an array or cluster or a group of radio antennas or satellite dishes located and placed in a specific area of land to detect and intercept any
