Stardust: We are Dead Stars
Yes, we are made of star stuff, to understand this let’s start from the beginning, right after the Big Bang when the early stars began to form from the newly created Hydrogen(H) and Helium(He) present in the Primordial soup. Then, in the core of the stars, a process called Stellar nucleosynthesis took place. What […]
Quasars: The Cosmic Serial Killers
In the vast expanse of the universe, there exist monsters so powerful that they can devour entire galaxies. These monsters are called Quasars. What are Quasars? Quasars are incredibly bright objects that are powered by supermassive black holes. The black hole’s intense gravitational pull sucks in gas and dust from the surrounding galaxy, which is […]

Cosmic Mirages: Unveiling the Mysteries of Gravitational Lensing
What if someone tells you, you can watch the invisible? Or that you can bend light? Of Course, you will find it impossible to do. However, what if I tell you that the beauty of physics provides that superpower to make it possible? Gravitational lensing is a very eccentric phenomenon that can do the impossible! […]
Beyond the Beyond: Peeking Into Parallel Universes
Have you ever wondered what lies beyond the edge of our Universe? There may be a possibility of parallel universes in which scientists are still brainstorming. It’s intriguing to imagine that in one universe, you are a virtuous individual, while in another, you embody the opposite. But is this real or just a hypothesis? What […]
Astrobiology: The Life Next Door
“Somewhere, something incredible is waiting to be known” – Carl Sagan We, humans, are always intrigued by the existence of life and its vast forms. From the playful dolphins springing and diving into the sea, the polar bears adapted to living in the freezing temperatures; the immovable autotrophic vegetation, the microscopic bacteria and viruses capable […]
A Bon Voyage – The Story of the Voyagers in Space
