Cosmic rays are high-energy protons and atomic nuclei that move through space at nearly the speed of light. They originate from various sources, including the Sun, supernovae, and other extreme astrophysical events. When they hit Earth's atmosphere, they create showers of secondary particles. Studying cosmic rays helps scientists understand the universe's most energetic processes.
An electron volt is a unit of energy commonly used in atomic and particle physics. It is defined as the amount of kinetic energy gained by a single electron when it accelerates through an electric potential difference of one volt. One quadrillion electron volts (10^15 eV) represents an extremely high energy level, far beyond what can be achieved in terrestrial laboratories.
The Milky Way is the galaxy that contains our Solar System. It is a barred spiral galaxy with a diameter of about 100,000 120,000 light-years and contains 100 400 billion stars. Our Sun is located in one of its spiral arms. The Milky Way is part of the Local Group of galaxies and is constantly interacting with its neighbours.
UPSC and SSC often ask about recent scientific discoveries, their implications, and fundamental concepts in physics and astronomy. Be prepared for questions on cosmic rays, particle accelerators, and the structure of the Milky Way.
