Mercury (planet)
Mercury is the first planet from the Sun. It is a rocky planet with a trace atmosphere. While it is the List of Solar System objects by size, smallest and least massive planet of the Solar System, its surface gravity is slightly higher than that of Mars. The surface of Mercury is similar to Earth's Moon, heavily Impact crater, cratered, with expansive rupes system, generated from thrust faults, and bright ray systems, formed by ejecta. Its largest crater, Caloris Planitia, has a diameter of , which is about one-third the diameter of the planet (). Being the most inferior planet, inferior orbiting planet it appears in Earth's sky, always close to the Sun, either as a "morning star" or an "evening star". It stays most of the time the closest to all other planets and is the planet with the highest delta-v needed to travel to from all other planets of the Solar System. Mercury's sidereal year (88.0 Earth days) and sidereal day (58.65 Earth days) are in a 3:2 ratio. This relation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acute Radiation Syndrome
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. Symptoms can start within an hour of exposure, and can last for several months. Early symptoms are usually nausea, vomiting and loss of appetite. In the following hours or weeks, initial symptoms may appear to improve, before the development of additional symptoms, after which either recovery or death follows. ARS involves a total dose of greater than 0.7 Gy (70 rad), that generally occurs from a source outside the body, delivered within a few minutes. Sources of such radiation can occur accidentally or intentionally. They may involve nuclear reactors, cyclotrons, certain devices used in cancer therapy, nuclear weapons, or radiological weapons. It is generally divided into three types: bone marrow, gastrointestinal, and neurovascular syndrome, with bone m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Daily Telegraph
''The Daily Telegraph'', known online and elsewhere as ''The Telegraph'', is a British daily broadsheet conservative newspaper published in London by Telegraph Media Group and distributed in the United Kingdom and internationally. It was founded by Arthur B. Sleigh in 1855 as ''The Daily Telegraph and Courier''. ''The Telegraph'' is considered a newspaper of record in the UK. The paper's motto, "Was, is, and will be", was included in its emblem which was used for over a century starting in 1858.

Jodrell Bank Observatory
Jodrell Bank Observatory ( ) in Cheshire, England hosts a number of radio telescopes as part of the Jodrell Bank Centre for Astrophysics at the University of Manchester. The observatory was established in 1945 by Bernard Lovell, a radio astronomer at the university, to investigate cosmic rays after his work on radar in the Second World War. It has since played an important role in the research of meteoroids, quasars, pulsars, masers, and gravitational lenses, and was heavily involved with the tracking of space probes at the start of the Space Age. The main telescope at the observatory is the Lovell Telescope. Its diameter of makes it the third largest steerable radio telescope in the world. There are three other active telescopes at the observatory; the Mark II and and 7 m diameter radio telescopes. Jodrell Bank Observatory is the base of the Multi-Element Radio Linked Interferometer Network (MERLIN), a National Facility run by the University of Manchester o ...

Bernard Lovell
Sir Alfred Charles Bernard Lovell ( ; 31 August 19136 August 2012) was an English physicist and radio astronomer. He was the first director of Jodrell Bank Observatory, from 1945 to 1980. Early life and education Lovell was born at Oldland Common, Bristol, in 1913, the son of local tradesman and Methodist preacher Gilbert Lovell (1881–1956) and Emily Laura, née Adams. Gilbert Lovell was an "authority on the Bible" and, having "studied English literature and grammar", was still "bombarding his son with complaints on points of grammar, punctuation and method of speaking" when Lovell was in his forties. Lovell's childhood hobbies and interests included cricket and music, mainly the piano. He had a Methodist upbringing and attended Kingswood Grammar School. Career and research Lovell studied physics at the University of Bristol obtaining a Bachelor of Science degree in 1934, and a PhD in 1936 for his work on the electrical conductivity of thin films. At this time, he also re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active SETI
Active SETI (Active Search for Extra-Terrestrial Intelligence) are attempts to send messages to intelligent extraterrestrial life. Active SETI messages are predominantly sent in the form of radio signals. Physical messages like that of the Pioneer plaque may also be considered an active SETI message. Active SETI is also known as METI (Messaging to Extra-Terrestrial Intelligence). Whether humans should engage in Active SETI is controversial due to concerns about potential impacts of extraterrestrial contact, sparking a vigorous policy debate. History 'Active SETI' was a term as early as 2005, though some decades after the term SETI. The term METI was coined in 2006 by Russian scientist Alexander Zaitsev, who proposed a subtle distinction between Active SETI and METI: Concern over METI was raised by the science journal ''Nature'' in an editorial in October 2006, which commented on a recent meeting of the International Academy of Astronautics SETI study group.

The Morse Message (1962)
The Morse Message was a series of brief radio messages in Russian Morse code that were transmitted from the Evpatoria Planetary Radar (EPR) complex and directed to the planet Venus in 1962. The message consisted of three words, all encoded in Morse code: the word “Mir” (, meaning both “peace” and “world”) was transmitted from the EPR on November 19, 1962, and the words “Lenin” () and “USSR” (, the abbreviation for the Soviet Union — , ''Soyúz Soviétskikh Sotsialistícheskikh Respúblik'') were transmitted on November 24, 1962. In Russian, the Morse Message is referred to as the Radio Message “MIR, LENIN, USSR”. The message was the first radio broadcast intended for extraterrestrial civilizations in the history of mankind. It was also used to test the radar station (though not for measuring the distance to Venus, since the EPR relied on a different technology, a coherent waveform with frequency manipulation, for distance measurements). The signals ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
