Sahaana Vijay Introduction Before unravelling the mysteries of the Universe, it is important for us to know about our origin and our place in this vast domain. We have been walking on this earth for the past three to seven million years and have evolved drastically. The earliest Homo sapiens dispersed out of Africa around …

Abstract Mankind has always been interested in the vast void that we called space. Filled with endless unknowns and bizarre phenomena, people throughout history such as Aristotle, Galileo, and many more have made impactful developments in our knowledge about the universe. Ever since Sputnik 1, the first mission that successfully delivered a satellite into Earth\’s …
The possibility of extraterrestrial life has been discussed for centuries, in both scientific and fictitious work. But it wasn’t until 1992 that the first exoplanet (planet outside of our solar system) was detected, and 2001 that the first exoplanet in a habitable zone was detected [1]. This makes exoplanetology and astrobiology relatively new fields of …
Introduction Did you know that a mere 5% of the universe consists of normal matter?

Life on Earth only goes until the 3rd dimension. The human brain cannot imagine something that it has never been exposed to (such as the 4th dimension). It would be like envisioning …
A black hole is a region in space-time where the gravity is so strong that nothing can escape; not even light (which is why they appear black). That is why, when Stephen Hawking found a theoretical argument for the existence of a type of black hole radiation, it took the scientific world by storm. This, …
