The Hawking Radiation Paradox
What happens to all the quantum information in a black hole when it evaporates? This is the main question of the hawking paradox. First what is quantum information? Quantum information is the information of the particles of a substance like the bonds between atoms. In quantum terms, this is stored as the entanglement states(two particles…

Tidal Disruption Event
A Tidal Disruption Event (TDE) is a violent cosmic phenomenon that occurs when a star passes too close to a supermassive black hole and is ripped apart by the black hole’s immense gravitational tidal forces. Three main key Stages are involved in this event: Spaghettification: As the star approaches the black hole, the gravitational pull…

The Life Cycle of Stars
The life cycle a star can be millions to trillions of years long. It begins in a cosmic cloud of dust and gas called a nebula, where gravity collapses matter into a protostar. This ignites nuclear fusion, fueling the star for its long, stable lifetime. The Life Cycle Birth of a star All stars are…

Hunting Exoplanets
“What is outside our solar system” Exoplanets are the distant planets outside our solar system. Hunting exoplanets is the search for planets orbiting stars outside our solar system. Astronomers rely on clever techniques—most notably the Transit Method (watching a star dim as a planet crosses its face) and the Radial Velocity Method (measuring a star’s…

Dark matter
Dark matter is an invisible form of matter that does not interact with light or other electromagnetic radiation. Originally known as the “missing mass,” dark matter’s existence was first inferred by Swiss American astronomer Fritz Zwicky, who in 1933 discovered that the mass of all the stars in the Coma cluster of galaxies provided only about 1 percent of the mass…

Sunspots
The outer part surrounding or region is called as the Penumbra. The inner black part of a sunspot is known as the Umbra. It appears darker than the surroundings as its cooler than them. What are sunspots and how are they formed? Sunspots are temporary spots on the Sun’s surface that are darker than its…

Magnetars
“A gravity prison for the universe” Can you imagine a magnet so powerful that it could wipe every credit card on Earth from a distance halfway to the moon? That is how strong the magnetic field of a magnetar is! A magnetar is an exotic type of neutron star, its defining feature that it has…
