For billions of years, small clumps of matter began to gravitationally clump into each other in slightly denser areas and attracted nearby matter. They thus grew even denser, forming new clouds, present-day stars, galaxies, and other astronomical structures observable today. The attribute of this process depended on the type and…
The Big Bang Theory helps explain and predict various phenomena in the Universe that astrophysical observations suggest. Based on this, we will study 2 models that physicists had discovered in the early 20th century but failed to gather enough evidence to explain why this was happening. However, after the advent…
Hubble Space Telescope, a wonder of optical telescopes, was launched into low Earth orbit in the 1900s and remains operational till now. It has been the most versatile and one of the most useful telescopes ever built, well known both as a research tool and public relations boon for astronomy.…
In the year 1916, Albert Einstein predicted the existence of Black Holes as a region in spacetime where the gravitational force of an object is so much that not even light can escape from there. The term “Black Hole” was coined by American astronomer John Wheeler many years later in…
A Dwarf Galaxy is a very small galaxy consisting of stars of order of 100 million to several billion stars. The Large Magellanic Cloud, which is a member galaxy of the Local group along with the Milky Way contains 30 billion stars as compared to the star count of 200-400…
Aurora Borealis, also referred to as sometimes the northern lights or, also by the name of polar lights is a magnificent phenomenon viewable at high latitude regions near Arctic and Antarctica. Auroras occur due to disturbances in the magnetic environment of the sun, often referred to as the magnetosphere. The…
