Transit Of Earth From Mars
frameless, upright=0.5, right A transit of Earth across the Sun as seen from Mars takes place when the planet Earth passes directly between the Sun and Mars, obscuring a small part of the Sun's disc for an observer on Mars. During a transit, Earth would be visible from Mars as a small black disc moving across the face of the Sun. They occur every 26, 79 and 100 years, and every ~1,000 years, there is an extra 53rd-year transit. Conjunctions Transits of Earth from Mars usually occur in pairs, with one following the other after 79 years; rarely, there are three in the series. The transits also follow a 284-year cycle, occurring at intervals of 100.5, 79, 25.5, and 79 years; a transit falling on a particular date is usually followed by another transit 284 years later. Transits occurring when Mars is at its ascending node take place in May, those at descending node happen in November. This cycle corresponds fairly closely to 151 Mars orbits, 284 Earth orbits, and 133 synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth And Moon Transit From Mars 2084
Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation, while large sheets of ice at Earth's polar deserts retain more water than Earth's groundwater, lakes, rivers, and atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth has a liquid outer core that generates a magnetosphere capable of deflecting most of the destructive solar winds and cosmic radiation. Earth has a dynamic atmosphere, which sustains Earth' ...

Viking 1
''Viking 1'' was the first of two spacecraft, along with '' Viking 2'', each consisting of an orbiter and a lander, sent to Mars as part of NASA's Viking program. The lander touched down on Mars on July 20, 1976, the first successful Mars lander in history. ''Viking 1'' operated on Mars for days (over 6 years) or Martian solar days, the longest extraterrestrial surface mission until the record was broken by the ''Opportunity'' rover on May 19, 2010. Mission Following launch using a Titan/Centaur launch vehicle on August 20, 1975, and an 11-month cruise to Mars, the orbiter began returning global images of Mars about five days before orbit insertion. The ''Viking 1'' Orbiter was inserted into Mars orbit on June 19, 1976, and trimmed to a 1,513 x 33,000 km, 24.66 h site certification orbit on June 21. Landing on Mars was planned for July 4, 1976, the United States Bicentennial, but imaging of the primary landing site showed it was too rough for a safe landing. The la ...

Andrew Crommelin
Andrew Claude de la Cherois Crommelin (6 February 1865 – 20 September 1939) was an astronomer of French and Huguenot descent who was born in Cushendun, County Antrim, Ireland. He was educated in England at Marlborough College and Trinity College, Cambridge. After a spell teaching at Lancing College he found permanent employment at the Royal Greenwich Observatory in 1891. He joined the Royal Astronomical Society in 1888 and was its president from 1929-1931. In 1895 he joined the British Astronomical Association and was president from 1904-1906 and directed its comet section 1898-1901 and 1907-1938. In 1910 for their studies of Halley’s Comet Crommelin and Philip Herbert Cowell jointly received the Prix Jules Janssen from the Société astronomique de France. For this work they also received the Lindemann prize of the Astronomische Gesellschaft in Germany. In 1914 Crommelin published an introductory book on astronomy “The Star World”.

Monthly Notices Of The Royal Astronomical Society
''Monthly Notices of the Royal Astronomical Society'' (MNRAS) is a peer-reviewed scientific journal in astronomy, astrophysics and related fields. It publishes original research in two formats: papers (of any length) and letters (limited to five pages). MNRAS publishes more articles per year than any other astronomy journal. The learned society journal has been in continuous existence since 1827 and became online only in 2020. It operates as a partnership between the Royal Astronomical Society (RAS), who select and peer-review the contents, and Oxford University Press (OUP), who publish and market the journal. Despite its name, MNRAS is no longer monthly, nor does it carry the notices of the RAS. In 2024 MNRAS became a purely gold open access journal. History The first issue of MNRAS was published on 9 February 1827 as ''Monthly Notices of the Astronomical Society of London'' and it has been in continuous publication ever since. It took its current name from the second vo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Marth
Albert Marth (5 May 1828 – 6 August 1897) was a German astronomer who worked in United Kingdom, Britain and Ireland. Life After studying theology at the University of Berlin, his interest in astronomy and mathematics led him to study astronomy under Christian August Friedrich Peters, C. A. F. Peters at the University of Königsberg. Marth went to England in 1853 to work for George Bishop (astronomer), George Bishop, a rich wine merchant and patron of astronomy, who financed George Bishop's Observatory, a London observatory (in operation from 1836 to 1861). At that time, paid jobs in astronomy were quite rare. He worked as William Lassell's assistant in Malta, discovering 600 nebulae. He also discovered one of the early asteroids found, 29 Amphitrite, and the galaxies NGC 3, NGC 4 and NGC 15. He also investigated double stars, discovering NGC 30 in 1864. From 1883 to 1897 he worked at the Markree Observatory in County Sligo where he was the second director appointed in it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transit Of Mercury From Mars
frameless, upright=0.5 A transit of Mercury across the Sun as seen from Mars takes place when the planet Mercury passes directly between the Sun and Mars, obscuring a small part of the Sun's disc for an observer on Mars. During a transit, Mercury can be seen from Mars as a small black disc moving across the face of the Sun. Transits of Mercury from Mars are roughly twice as common as transits of Mercury from Earth: there are several per decade. Transit The Mars rovers '' Spirit'' and ''Opportunity'' could have observed the transit of January 12, 2005 (from 14:45 UTC to 23:05 UTC); however the only camera available for this had insufficient resolution. They were able to observe transits of Deimos across the Sun, but at 2' angular diameter, Deimos is about 20 times larger than Mercury's 6.1" angular diameter. Ephemeris data generated bJPL Horizonsindicates that ''Opportunity'' would have been able to observe the transit from the start until local sunset at about 19:23 UTC, while ...

Transit Of Phobos From Mars
A transit of Phobos across the Sun as seen from Mars takes place when Phobos (moon), Phobos passes directly between the Sun and a point on the surface of Mars, obscuring a large part of the Sun's disc for an observer on Mars. During a astronomical transit, transit, Phobos can be seen from Mars as a large black disc rapidly moving across the face of the Sun. At the same time, the shadow (antumbra) of Phobos moves across the Martian surface. The event could also be regarded as a particularly quick and shallow annular solar eclipse by Phobos. Transit A transit of Phobos from Mars usually lasts only thirty seconds or so, due to the moon's very rapid orbital period of approximately 7.6 hours. Because Phobos orbits close to Mars and in line with its equator, transits of Phobos occur somewhere on Mars on most days of the Martian year. Its orbital inclination is 1.08°, so the latitude of its shadow projected onto the Martian surface shows a seasonal variation, moving from 70.4°S ...

Astronomical Transit
In astronomy, a transit (or astronomical transit) is the passage of a astronomical object, celestial body directly between a larger body and the observer. As viewed from a particular vantage point, the transiting body appears to move across the face of the larger body, eclipse, covering a small portion of it. The word "transit" refers to cases where the nearer object apparent size, appears smaller than the more distant object. Cases where the nearer object appears larger and completely hides the more distant object are known as occultation, ''occultations''. However, the probability of seeing a transiting planet is low because it is dependent on the alignment of the three objects in a nearly perfectly straight line. Many parameters of a planet and its parent star can be determined based on the transit. In the Solar System One type of transit involves the motion of a planet between a Earth, terrestrial observer and the Sun. This can happen only with inferior and superior pla ...

List Of Future Astronomical Events
A list of future observable astronomical events, of the classical variety: those seen by eyesight, or happen within the Solar System. These are by no means all events, but only the notable or rare ones. In particular, it does not include all solar eclipses or lunar eclipses unless otherwise notable, as they are far too numerous to list (see below for articles with lists of all these). Nor does it list astronomical events that have yet to be discovered. Some points of the list miss the last date of the events. 21st century 22nd to 30th centuries Long solar eclipses :1The eclipse of 2045 will be visible from the United States, producing a path from California to Florida. Some parts of Florida are predicted to experience totality for six minutes, the longest in US history. :2Exceeding 7 minutes of totality, this will be the first time this has happened in 177 years; the last one occurred on June 30, 1973, when the Concorde prototype followed the totality spot for 73 minutes. ...
