Astrophysics
Astrophysics is a branch of astronomy that applies the principles of physics and chemistry to understand the nature of celestial bodies and cosmic phenomena. It encompasses the study of the Sun, stars, galaxies, exoplanets, the interstellar medium, and the cosmic microwave background, analyzing their luminosity, density, temperature, and chemical composition.
Aurora Borealis
The Aurora Borealis, or Northern Lights, is a natural light display predominantly seen in high-latitude regions around the Arctic. This phenomenon results from the interaction between charged particles from the sun and Earth's magnetic field, leading to vibrant, dynamic patterns in the night sky.
Dark Matter
Dark matter is a form of matter that does not interact with electromagnetic radiation, making it invisible to current detection methods. Its existence is inferred from gravitational effects on visible matter, such as the rotational speeds of galaxies and gravitational lensing.
Quasar
A quasar is an extremely luminous active galactic nucleus powered by a supermassive black hole, emitting energy across the electromagnetic spectrum and often outshining its host galaxy.
