The "Great Moon Hoax", also known as the "Great Moon Hoax of 1835" was a series of six articles published in The Sun (a New York newspaper), beginning on August 25, 1835, about the supposed discovery of life and civilization on the Moon. The discoveries were falsely attributed to Sir John Herschel and his fictitious companion Andrew Grant. [1]
A NASA probe ventured closer to the sun than any spacecraft in history on Christmas Eve — and it whirled by at astounding speeds that also made it the fastest thing ever made by humans. Just ...
1924: Edwin Hubble: the discovery that the Milky Way is just one of many galaxies; 1925: Erwin Schrödinger: Schrödinger equation (Quantum mechanics) 1925: Cecilia Payne-Gaposchkin: Discovery of the composition of the Sun and that hydrogen is the most abundant element in the Universe; 1927: Werner Heisenberg: Uncertainty principle (Quantum ...
1970 — Roger Ulrich, John Leibacher, and Robert F. Stein deduce from theoretical solar models that the interior of the Sun could act as a resonant acoustic cavity; 1975 — Franz-Ludwig Deubner makes the first accurate measurements of the period and horizontal wavelength of the five-minute solar oscillations
Our Milky Way galaxy's most common type of star is called a red dwarf - much smaller and less luminous than our sun. But the discovery of a planet at least 13 times Earth's mass orbiting very ...
However, numerous discoveries in recent decades have pushed the timeline back even further. For example, archaeologists found older artifacts at a 14,500-year-old site in Chile.
Italian polymath Galileo Galilei was an early user and made prolific discoveries, including the phases of Venus, which definitively disproved the arrangement of spheres in the Ptolemaic system. Galileo also discovered that the Moon was cratered, that the Sun was marked with sunspots, and that Jupiter had four satellites in orbit around it. [13]
Following the discovery of Leleākūhonua, Sheppard et al. concluded that it implies a population of about 2 million inner Oort cloud objects larger than 40 km (25 mi), with a combined total mass of 1 × 10 22 kg, about the mass of Pluto (a fraction the mass of Earth's moon but several times the mass of the asteroid belt).
