The cosmic microwave background (CMB) is a faint radiation that permeates the universe.
Cosmic Microwave Background:
The universe is primarily composed of dark matter and dark energy, which together make up about 95% of its total content.
Dark Matter and Dark Energy:
Black holes are regions in space with gravitational forces so strong that nothing, not even light, can escape from them.
Black Holes:
Thousands of exoplanets have been detected so far, and ongoing missions and telescopes are expanding our knowledge of these distant worlds.
Exoplanets:
Gravitational waves are ripples in the fabric of spacetime caused by the acceleration of massive objects.
Gravitational Waves:
Space probes and rovers have been sent to various celestial bodies in our solar system, providing invaluable data and imagery.
Space Probes and Rovers:
Cosmic rays are high-energy particles, primarily protons and atomic nuclei, that originate from sources outside our solar system.
Cosmic Rays:
Supernovae are explosive events that occur at the end of a star's life. They release an enormous amount of energy and can briefly outshine entire galaxies.
Supernovae:
According to general relativity, mass and energy cause space and time to curve around them.
