[ad_1] The cosmos has a cellular appearance with massive “walls” and filaments of supercluster galaxies separated by vast voids. The observable cosmos appears to be 14.7 billion light-years across, but the effective diameter is 92-94 billion light-years. The largest known structure is the Sloan Great Wall, 1.37 billion light-years long. Our galaxy is in the […]
[ad_1] Cosmic rays, mostly protons, hit Earth’s atmosphere at varying energy levels. They are ionizing radiation and can cause damage to biomaterial. Most come from within our galaxy, but the most energetic come from outside and provide insight into the wider universe. Cosmic rays are tiny particles, mostly protons, that strike the Earth’s atmosphere at […]
[ad_1] Cosmic dust is a substance found throughout the universe, with varying compositions and properties. Originally considered a nuisance, it plays a vital role in the formation of stars and planets. There are different types of cosmic dust, and it can vary in size. Studies of cosmic dust can reveal insights into the formation and […]
[ad_1] Cosmic rays are energetic particles that can be detected when they collide with the upper atmosphere, allowing us to infer their energy and direction. Ultrahigh-energy cosmic rays (UHECRs) are those that exceed the Greisen-Zatsepin-Kuzmin (GZK) limit, and their existence is a mystery that may hint at new physical theories. The Oh-My-God particle, observed in […]
[ad_1] The cosmic microwave background is electromagnetic radiation throughout the universe, with a temperature of 2.725 K and a wavelength of 1.9 mm. It is evidence of the Big Bang and originated from the universe’s plasma period. It is mostly homogeneous and isotropic, and its spectrum is the most precisely measured black-body spectrum. The COBE […]
[ad_1] Cosmic irony occurs when a situation with a positive outcome results in a negative outcome due to an unknown force, such as fate or the universe. It is often used intentionally in literature and can be seen in historical situations, such as the introduction of the cane toad in Australia. One type of situational […]
