History of Astronomy
We have a very little information on early human’s impression of the heavens, mostly some drawings of eclipse, comets etc. One of the earliest recorded astronomical observations is the Nebra sky disk from northern Europe dating approximately 1,600 BC. Read more
Terminologies of Astronomy
We have looked into our past and saw how humanity understood the heavens in a much detailed way and true nature of the cosmos. We will be diving in more detailed stuff later on, but before that we need to understand the basic terminologies used in Astronomy. Read more
Solar System - Formation, Evolution & Fate
How it all began ?
Ever wondered how everything came into existence? The planets, Sun, Galaxies, Universe and even time itself. How did space and time come into existence? Let’s take a tour to a time where “Time” itself was born – 13.5 billion years ago. It all started with a Bang called “Big Bang”. Read More
Birth of Stars
All this begins when a huge cloud of interstellar dust gets concentrated in one region of space and time. Over the period of time gravity pulls the dust of cloud together and form a spinning ball of gas just like Jupiter. When more and more mass is added to the huge ball of spinning gas the mass of the spinning ball rises which eventually rise the temperature in its core. Read more
Formation of Black Hole
Black holes are the results of super massive collapsing stars. A star with a mass 20 times more than our sun may form a black hole at the end of its life. When a star runs out of fuel and the nuclear reaction comes to an end the gravity becomes the dominant force and push the star and all the matter present inside it towards the core. Read more
Gravity – Force or Curvature of Spacetime?
When we talk about space, normally we think it’s an isolated place where nothing exists. But in reality, space has nothing to do about nothingness (not even close). If you take out all the planets, galaxies, nebulas, stars, black hole and every matter present outside the universe, you will still be left with something called Space. It’s a real entity and is as real as gravity. We call it as fabric of space time. Read more
Basic Principles of Rocket Science
A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. A good example of this is a balloon. Air inside a balloon is compressed by the balloon’s rubber walls. Read more
How to choose your first Telescope ?
Humans’ fascination with the stars is as old as our ability to think and ask questions. For millennia we, as a species, were limited to observing the heavens with just our eyes. Of course, back then we were able to see more because light pollution didn’t exist, but making detailed observations was impossible. The invention of the microscope led to the development of the telescope, which allowed people to finally start exploring the larger universe. Read more
5 Inventions by Nikola Tesla that never got built
Tesla once said that “It seems that I have always been ahead of my time” and he meant that. He has contributed a lot to the modern society ranging from AC to robotics. Although he pioneered in many technological advancements but still many of his outlandish ideas never became a reality due to one or other reason. Read more
