In astrophysics, a gravitational wave is a wavering or fluctuation in space-time, traveling outwards from the source. In short, it is like a ‘ripple in space-time’, just like the small waves produced by a boat sailing through a sea. This is caused by large, moving celestial bodies such as stars and black holes. The more […]

Infrared in astronomy is defined as the branch of astronomy and astrophysics that studies astronomical objects that are visible through infrared (IR) radiation. This branch of astronomy can be traced back to the 1830s, notably a few decades after William Herschel discovered IR in the 1800s. He first experimented with a thermometer by placing it
If you?ve seen the movie ?Finding Nemo?, you?ll remember the scene where Nemo?s dad Marlin and his new companion Dory get directions to Sydney from a school of moonfish and ride the East Australian Current with a group of sea turtles. That ocean current is very much like a jet stream; only it?s high up
Most of the stars in the galaxy, including the Sun, are considered as main sequence stars. Main sequence stars are classified by their energy source. A star fuels itself by continually fusing hydrogen into helium within its core. The rate of this fusion varies relative to the mass of the star. The bigger the mass

The name micron itself is a giveaway to how diminutive it is in size. Microns represent a millionth of a meter, or about 0.00003937 inches. It is part of the metric system, commonly represented by mu/µ, the Greek Letter for M. This unit of length has been used by scientists from 1879 up to 1967,
How many times do you pass by your favorite ice cream parlor in a week? If you answer five times a week, then it is how frequent you pass by your favorite ice cream parlor in a week. That?s the simplest explanation of frequency. It is the number of times or the repetition of a
Water is an important element to sustain life. In order for a certain planet to support existence, it has to have liquid water on its surface. For this to be possible its effective surface temperature must be above the freezing point of water. A star like sun can provide energy radiation enough to maintain this
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
There is absolutely no life without the presence of light. Vision is not possible without the ability of the sun to illuminate objects. Even if the sun is 150 million kilometers away from earth, its rays are capable in providing the proper amount of heat and light needed for living things to survive.
The magnetopause is the layer that acts as the Earth’s shield from the solar wind. It is found between the surrounding plasma and magnetosphere or the magnetic field. The surface of the magnetopause has a complex shape. It flaps, ripples, and moves in different directions, inward or outward, depending on the solar wind conditions. The
