Richter Scale, developed in 1935 by Charles Richter, is typically a measurement of ground motion generally used for expressing the intensity of an earthquake. It is based on powers of ten which essentially means that an earthquake measuring ‘4’ on the Richter Scale has a recorded seismograph amplitude 10 times greater than the one measuring…
A solar eclipse is an astronomical event that occurs when the moon obscures the sun for some time. There are different kinds of solar eclipse – total, annular, hybrid and partial.

Sun, the pivotal element of the solar system, is a middle-aged star that is around 4.6 billion years old. This near-perfect sphere is made up of 70 per cent hydrogen and 28 per cent helium. With the amount of hydrogen left on it, it can survive for another 5 billion years. In the last stages…
