What is the Oort Cloud?
The Oort Cloud is a hypothetical spherical shell of icy objects located far beyond the Kuiper Belt, extending halfway to the nearest star. It is believed to be the source of long-period comets that occasionally enter the inner solar system.

The Kuiper Belt is a region of the solar system beyond the orbit of Neptune that is populated by small icy bodies, dwarf planets, comets, and other objects. It is considered the source of many short-period comets.

See lessWhat is cosmic microwave background radiation?
Cosmic microwave background radiation (CMBR) is the residual heat and radiation left over from the Big Bang, which permeates the universe uniformly and serves as a crucial piece of evidence supporting the Big Bang theory.

See lessWhat is a quasar?
A quasar is an extremely luminous and energetic active galactic nucleus powered by a supermassive black hole at the center of a galaxy. Quasars emit enormous amounts of radiation across the electromagnetic spectrum, making them visible from great distances.

See lessWhat is a pulsar?
A pulsar is a highly magnetized, rotating neutron star that emits beams of electromagnetic radiation, including radio waves, X-rays, and gamma rays, from its magnetic poles. These beams are observed as regular pulses of radiation as the pulsar rotates.

See lessWhat is a supernova?
A supernova is a powerful and luminous stellar explosion that occurs when a massive star reaches the end of its life cycle and undergoes a catastrophic collapse. Supernovae can outshine entire galaxies for a brief period and leave behind remnants such as neutron stars or black holes.

See lessWhat is dark energy?
Dark energy is a mysterious force that permeates the universe and is believed to be responsible for the observed acceleration of the universe's expansion. Its exact nature remains poorly understood.

See lessWhat is dark matter?
Dark matter is a hypothetical form of matter that does not emit, absorb, or reflect electromagnetic radiation, making it invisible and detectable only through its gravitational effects on visible matter and light.

See lessWhat is a nebula?
A nebula is a vast cloud of gas and dust in space, often illuminated by nearby stars or other light sources. Nebulae are regions where new stars are born or where old stars expel their outer layers.

See lessWhat is a black hole?
A black hole is a region of spacetime where gravity is so strong that nothing, not even light, can escape from it. Black holes form when massive stars collapse under their own gravity at the end of their life cycle.
