Badastronomy
''Bad Astronomy: Misconceptions and Misuses Revealed, from Astrology to the Moon Landing "Hoax"'' is a non-fiction book by the American astronomer Phil Plait, who is also known as "the Bad Astronomer". The book was published in 2002 and deals with various misunderstandings about space and astronomy, such as sounds being audible in space (a misconception because in the vacuum of space, sound has no medium in which to propagate). Plait's first book received generally favorable reviews within the academic and astronomy communities and was the first volume in the ''Bad Science'' series by John Wiley & Sons Publishing Overview Inspired by the author's web site, "Bad Astronomy", the book attempts to explore twenty-four common astronomical fallacies and explain the scientific consensus concerning these topics within the field of astronomy. The book explains and corrects many ideas relating to space that, according to Plait, are mistaken but nevertheless often portrayed in popular ...

Philip Plait
Philip Cary Plait (born September 30, 1964), also known as The Bad Astronomer, is an American astronomer, skeptic, and popular science blogger. Plait has worked as part of the Hubble Space Telescope team, images and spectra of astronomical objects, as well as engaging in public outreach advocacy for NASA missions. He has written three books, '' Bad Astronomy'', '' Death from the Skies'', and '' Under Alien Skies''.

Hubble Space Telescope
The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the Orbiting Solar Observatory, first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy. The Hubble Space Telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories program, Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a mirror, and its five main instruments observe in the ultraviolet, visible spectrum, visible, and near-infrared regions of the electromagnetic spectrum. Hubble's orbit outside the distortion of atmosphere of Earth, Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background lig ...

Astronomical Society Of The Pacific
The Astronomical Society of the Pacific (ASP) is an American scientific and educational organization, founded in San Francisco on February 7, 1889, immediately following the solar eclipse of January 1, 1889. Its name derives from its origins on the Pacific Coast, but today it has members all over the country and the world. It has the legal status of a nonprofit organization. It is the largest general astronomy education society in the world, with members from over 40 countries. Education and outreach programs The ASP's mission is to promote public interest in and awareness of astronomy (and increase scientific literacy) through its publications, web site, and many educational and outreach programs. * The NASA Night Sky Network – a community of more than 450 astronomy clubs across the U.S. that share their time and telescopes to engage the public with unique astronomy experiences. The ASP provides training and materials to enhance clubs outreach activities, and inspires more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unidentified Flying Objects
An unidentified flying object (UFO) is an object or phenomenon seen in the sky but not yet identified or explained. The term was coined when United States Air Force (USAF) investigations into flying saucers found too broad a range of shapes reported to consider them all saucers or discs. UFOs are also known as unidentified aerial phenomena or unidentified anomalous phenomena (UAP). Upon investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number remain unexplained. While unusual sightings in the sky have been reported since at least the 3rd century BC, UFOs became culturally prominent after World War II, escalating during the Space Age. Studies and investigations into UFO reports conducted by governments (such as Project Blue Book in the United States and Project Condign in the United Kingdom), as well as by organisations and individuals have occurred over the years without confirmation of the fantastical claims of small but vo ...

Jupiter
Jupiter is the fifth planet from the Sun and the List of Solar System objects by size, largest in the Solar System. It is a gas giant with a Jupiter mass, mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Its diameter is 11 times that of Earth and a tenth that of the Sun. Jupiter orbits the Sun at a distance of , with an orbital period of . It is the List of brightest natural objects in the sky, third-brightest natural object in the Earth's night sky, after the Moon and Venus, and has been observed since prehistoric times. Its name derives from that of Jupiter (god), Jupiter, the chief deity of ancient Roman religion. Jupiter was the first of the Sun's planets to form, and its inward migration during the primordial phase of the Solar System affected much of the formation history of the other planets. Jupiter's atmosphere consists of 76% hydrogen and 24% helium by mass, with a denser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venus
Venus is the second planet from the Sun. It is often called Earth's "twin" or "sister" planet for having almost the same size and mass, and the closest orbit to Earth's. While both are rocky planets, Venus has an atmosphere much thicker and denser than Earth and any other rocky body in the Solar System. Its atmosphere is composed of mostly carbon dioxide (), with a global sulfuric acid cloud cover and no liquid water. At the mean surface level the atmosphere reaches a temperature of and a pressure 92 times greater than Earth's at sea level, turning the lowest layer of the atmosphere into a supercritical fluid. Venus is the third brightest object in Earth's sky, after the Moon and the Sun, and, like Mercury, appears always relatively close to the Sun, either as a "morning star" or an "evening star", resulting from orbiting closer ( inferior) to the Sun than Earth. The orbits of Venus and Earth make the two planets approach each other in synodic periods of 1.6 years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Worlds In Collision
''Worlds in Collision'' is a book by Immanuel Velikovsky published in 1950. The book postulates that around the 15th century BC, the planet Venus was ejected from Jupiter as a comet or comet-like object and passed near Earth (an actual collision is not mentioned). The object allegedly changed Earth's orbit and axis, causing innumerable catastrophes that are mentioned in early mythologies and religions from around the world. The book has been heavily criticized as a work of pseudoscience and catastrophism, and many of its claims are completely rejected by the established scientific community as they are not supported by any available evidence. Publication ''Worlds in Collision'' was first published on April 3, 1950, by Macmillan Publishers. Macmillan's interest in publishing it was encouraged by the knowledge that Velikovsky had obtained a promise from Gordon Atwater, Director of the Hayden Planetarium, for a sky show based on the book when it was published. The book, Velikovsky's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immanuel Velikovsky
Immanuel Velikovsky (; rus, Иммануи́л Велико́вский, p=ɪmənʊˈil vʲɪlʲɪˈkofskʲɪj; 17 November 1979) was a Russian-American psychoanalyst, writer, and catastrophist. He is the author of several books offering Pseudohistory, pseudohistorical interpretations of ancient history, including the U.S. bestseller ''Worlds in Collision'' published in 1950. Velikovsky's work is frequently cited as a canonical example of pseudoscience and has been used as an example of the demarcation problem. His books use comparative mythology and ancient literature, ancient literary sources (including the Old Testament) to argue that Earth suffered catastrophism, catastrophic close contacts with other planets (principally Venus and Mars) in ancient history. In positioning Velikovsky among catastrophism, catastrophists including Hans Schindler Bellamy, Hans Bellamy, Ignatius L. Donnelly, Ignatius Donnelly, and , the British astronomers Victor Clube and Bill Napier noted "...&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
