Lomonosov (Martian crater)
Lomonosov is a crater on Mars, with a diameter close to 150 km. It is located in the Martian northern plains. Since it is large and found close (64.9° north) to the boundary between the Mare Acidalium quadrangle and the Mare Boreum quadrangle, it is found on both maps. The topography is smooth and young in this area, hence Lomonosov is easy to spot on large maps of Mars.
Gregorian calendar
The Gregorian calendar is the most widely used civil calendar in the world. It is named after Pope Gregory XIII, who introduced it in October 1582. The calendar spaces leap years to make the average year 365.2425 days long, approximating the 365.2422 day tropical year that is determined by the Earth's revolution around the Sun. The rule for leap years is as follows:
The Bach Sinfonia
The Bach Sinfonia is an American musical ensemble based out of Washington D.C. that specializes in the performance of 18th-century music using historically informed performance practices. Founded in 1995 by music director Daniel Abraham, the ensemble consists of an orchestra reflecting the size and instrumentation of the baroque period as well as a number of vocal and instrumental soloists. The ensemble has been featured on National Public Radio's "Performance Today" and has recorded works by Johann Sebastian Bach and George Frideric Handel.
Age of Enlightenment
French historians traditionally place the Enlightenment between 1715, the year that Louis XIV died, and 1789, the beginning of the French Revolution. Some recent historians begin the period in the 1620s, with the start of the scientific revolution. The Philosophes, the French term for the philosophers of the period, widely circulated their ideas through meetings at scientific academies, Masonic lodges, literary salons and coffee houses, and through printed books and pamphlets. The ideas of the Enlightenment undermined the authority of the monarchy and the church, and paved the way for the revolutions of the 18th and 19th centuries. A variety of 19th-century movements, including liberalism and neo-classicism, trace their intellectual heritage back to the Enlightenment.
Orbit of the Moon
The Moon orbits Earth in the prograde direction and completes one revolution relative to the stars in about 27.32 days (a sidereal month) and one revolution relative to the Sun in about 29.53 days (a synodic month). Earth and the Moon orbit about their barycenter (common center of mass), which lies about 4,600 km (2,900 mi) from Earth's center (about 3 / 4 of the radius of Earth). On average, the distance to the Moon is about 385,000 km (239,000 mi) from Earth's center, which corresponds to about 60 Earth radii.
Mercury (planet)
Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of 88 days is the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger to the gods.
Verde Vallis
Verde Vallis is an ancient river valley in the Sinus Sabaeus quadrangle on Mars. It is found in the Sinus Sabaeus quadrangle at 0.5° south latitude and 330.2° west longitude. It is named after a river in Arizona, USA.
Halley's Comet
Halley's Comet or Comet Halley, officially designated 1P / Halley, is a short - period comet visible from Earth every 74 -- 79 years. Halley is the only known short - period comet that is regularly visible to the naked eye from Earth, and the only naked - eye comet that might appear twice in a human lifetime. Halley last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061.
History of science
The willingness to question previously held truths and search for new answers resulted in a period of major scientific advancements, now known as the Scientific Revolution. The Scientific Revolution is traditionally held by most historians to have begun in 1543, when the books De humani corporis fabrica (On the Workings of the Human Body) by Andreas Vesalius, and also De Revolutionibus, by the astronomer Nicolaus Copernicus, were first printed. The thesis of Copernicus' book was that the Earth moved around the Sun. The period culminated with the publication of the Philosophiæ Naturalis Principia Mathematica in 1687 by Isaac Newton, representative of the unprecedented growth of scientific publications throughout Europe.
Rare-earth element
A rare - earth element (REE) or rare - earth metal (REM), as defined by IUPAC, is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare - earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. For the same set of mineralogical, chemical, physical (especially electron shell configuration), and related reasons, a broader definition of rare earth elements including the actinides is encountered in some cases. Thorium is a significant component of monazite and other important rare earth minerals, and uranium and decay products are found in others. Both series of elements begin on the periodic table in group 3 under yttrium and scandium.
Biodiversity
The age of the Earth is about 4.54 billion years old. The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon. There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old metasedimentary rocks discovered in Western Greenland. More recently, in 2015, "remains of biotic life" were found in 4.1 billion-year-old rocks in Western Australia. According to one of the researchers, "If life arose relatively quickly on Earth ... then it could be common in the universe."
Emil Bach House
The Emil Bach House is a Prairie style house in the Rogers Park neighborhood of Chicago, Illinois, United States that was designed by famous architect Frank Lloyd Wright. The house was built in 1915 for an admirer of Wright's work, Emil Bach. Bach was co-owner of the Bach Brick Company. The house is representative of Wright's late Prairie style and is an expression of his creativity from a period just before his work shifted stylistic focus. The Bach House was declared a Chicago Landmark on September 28, 1977, and was added to the U.S. National Register of Historic Places on January 23, 1979.
Classical period (music)
The best - known composers from this period are Joseph Haydn, Wolfgang Amadeus Mozart, Ludwig van Beethoven, and Franz Schubert; other notable names include Luigi Boccherini, Muzio Clementi, Antonio Salieri, Leopold Mozart, Johann Christian Bach, Carl Philipp Emanuel Bach, and Christoph Willibald Gluck. Ludwig van Beethoven is regarded either as a Romantic composer or a Classical period composer who was part of the transition to the Romantic era. Franz Schubert is also a transitional figure, as were Johann Nepomuk Hummel, Luigi Cherubini, Gaspare Spontini, Gioachino Rossini, and Carl Maria von Weber. The period is sometimes referred to as the era of Viennese Classic or Classicism (German: Wiener Klassik), since Gluck, Mozart, Haydn, Salieri, Schubert, and Beethoven all worked in Vienna.
Carl Philipp Emanuel Bach
Carl Philipp Emanuel Bach (8 March 1714 – 14 December 1788), also formerly spelled Karl Philipp Emmanuel Bach, was a German Classical period musician and composer, the fifth child and second (surviving) son of Johann Sebastian Bach and Maria Barbara Bach. His second name was given in honor of his godfather Georg Philipp Telemann, a friend of Johann Sebastian Bach.
Acidalia Planitia
Acidalia Planitia is a plain on Mars. It is located between the Tharsis volcanic province and Arabia Terra to the north of Valles Marineris, centered at . Most of this region is found in the Mare Acidalium quadrangle, but a small part is in the Ismenius Lacus quadrangle. The plain contains the famous Cydonia region at the contact with the heavily cratered highland terrain.
Lunae Palus quadrangle
The Lunae Palus quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The quadrangle is also referred to as MC-10 (Mars Chart-10). Lunae Planum and parts of Xanthe Terra and Chryse Planitia are found in the Lunae Palus quadrangle. The Lunae Palus quadrangle contains many ancient river valleys.
Saturn
The average distance between Saturn and the Sun is over 1.4 billion kilometers (9 AU). With an average orbital speed of 9.68 km / s, it takes Saturn 10,759 Earth days (or about ​ 29 ⁄ years) to finish one revolution around the Sun. As a consequence, it forms a near 5: 2 mean - motion resonance with Jupiter. The elliptical orbit of Saturn is inclined 2.48 ° relative to the orbital plane of the Earth. The perihelion and aphelion distances are, respectively, 9.195 and 9.957 AU, on average. The visible features on Saturn rotate at different rates depending on latitude and multiple rotation periods have been assigned to various regions (as in Jupiter's case).
Terra Sabaea
Terra Sabaea is a large area on Mars. Its coordinates are and it covers at its broadest extent. It was named in 1979 after a classic albedo feature on the planet. Terra Sabaea is fairly large and parts of it are found in five quadrangles: Arabia quadrangle, Syrtis Major quadrangle, Iapygia quadrangle, Ismenius Lacus quadrangle, and Sinus Sabaeus quadrangle.
Atlantis basin
Atlantis basin is an eroded impact crater in the southern hemisphere of Mars, in the Phaethontis quadrangle, Sirenum Terrae region, centered at 177° West, 35° South. It was formed during the early Noachian period.
Bach quadrangle
The Bach quadrangle encompasses the south polar part of Mercury poleward of latitude 65° S. It is named for Baroque composer Johann Sebastian Bach (1685-1750).
