A lot has been said about the Big Bang event that is believed to have created the universe about 13.7 billion years ago. The Big Bang event draws its conclusion of the expansion of the universe because of the red-shifting light that are seen from distant galaxies and clusters of galaxies. However, aside from the […]
Nucleus, known as a center, may mean a lot of things. Reviewing your Biology, it is also known as the control center. Going to Chemistry, it is the center of an atom that has the protons and neutrons. Now, in Astronomy, you should know that the galaxy also has a nucleus. And it is called
For thousands of years, ancient civilizations have thought of the earth as the center of the solar system. Had Copernicus failed to challenge this belief, Galileo would not have concluded that the solar system is indeed heliocentric. If his proponent theory gathered much of a dispute, imagine the disbelief it would cause by suggesting that

When you look at the stars, you will notice that some of them are brighter than the others. The differences in brightness are assigned with specific numbers that correspond to their magnitude. Magnitude starts from -1, which is considered as the brightest star. The dimmer a star becomes, it gets a number with a higher
Seeing comets is an awesome experience. Being able to see a very rare comet in one’s lifetime is truly one unforgettable moment. Comets despite its very bright and seemingly burning appearance are actually bodies of ice in the Solar System. When these comets get near the Sun, a coma may be visible to stargazers or

In defining a plane, you can describe it as a flat two-dimensional surface. But how could a not perfectly co-planar Milky Way have a plane? Galaxies are normally irregular in shape. In space or in a galaxy, a plane is described as where most of the galaxy’s mass lies. It is then called the galactic
Stellar mass loss is a phenomenon that occurs in massive stars. This phenomenon is observed when a big portion of the mass of a star is triggered by specific events. Stellar mass loss happen can also when a giant star loses its material little by little into interstellar space or due to binary companion.
The general meaning of the word inclination is the angle between a reference plane and another plane or axis of direction. When it comes to astronomy, it is defined as a measure of the tilt of a certain planet’s orbital plane in relation to that of Earth.
It was in 1913 when a radio-chemist named Frederick Soddy first suggested the existence of isotopes. He noticed that the periodic table of elements only allowed for 11 elements ranging from uranium to lead. However, several types of atoms which differ in radioactive properties can still occupy the same place in the table.
In astronomy or the study of space, a lot of terms come to mind, whether it is galaxies, the universe or the cosmos come into place when this particular subject is discussed. Speaking of which, the most common term when it comes to space are the galaxies, which is defined as a bound and gravitational
