Israeli Astronomical Association
The Israeli Astronomical Association (IAA) is an Israeli nonprofit organization. Its purpose is to deepen and distribute the awareness for the field of astronomy among the Israeli public. History The Israeli Astronomical Association was established first as an amateur fellowship on May 28, 1951, by a group of astronomy fans immigrating from Germany and Czechoslovakia, among them Dr Heilbruner and Dr Zaichik. Dr Zaichik was the first chairman of the association and kept his position for many years until his retirement due to personal health matters. The decision to make the association national was made in 1953 in the chamber of David Ben-Gurion, the country's prime minister, in order to promote astronomical knowledge and related science fields in the newly formed state of Israel. The association was then allocated a territory in Givat Ram in Jerusalem by the Israel Land Administration. The same area was later designated for the development of the Hebrew University of Jerusalem. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronomy Organizations
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professional a ...

Amateur Astronomy
Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies. Amateur astronomers do not use the field of astronomy as their primary source of income or support, and usually have no professional degree in astrophysics or advanced academic training in the subject. Most amateurs are hobbyists, while others have a high degree of experience in astronomy and may often assist and work alongside professional astronomers. Many astronomers have studied the sky throughout history in an amateur framework; however, since the beginning o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Israeli Shekel
The new Israeli shekel ( he, שֶׁקֶל חָדָשׁ '; ar, شيكل جديد ; sign: ₪; ISO code: ILS; abbreviation: NIS), also known as simply the Israeli shekel ( he, שקל ישראלי, ar, شيكل إسرائيلي), is the currency of Israel and is also used as a legal tender in the Palestinian territories of the West Bank and the Gaza Strip. The new shekel is divided into 100 agorot. The new shekel has been in use since 1 January 1986, when it replaced the hyperinflated old shekel at a ratio of 1000:1. The currency sign for the new shekel is a combination of the first Hebrew letters of the words ''shekel'' () and ''ẖadash'' () (new). When the shekel sign is unavailable the abbreviation ''NIS'' ( and ) is used. History The origin of the name "shekel" () is from the ancient Biblical currency by the same name. An early Biblical reference is Abraham being reported to pay "four hundred shekels of silver" to Ephron the Hittite for the Cave of the Patriarc ...

Tel Aviv University
Tel Aviv University (TAU) ( he, אוּנִיבֶרְסִיטַת תֵּל אָבִיב, ''Universitat Tel Aviv'') is a public research university in Tel Aviv, Israel. With over 30,000 students, it is the largest university in the country.

Wise Observatory
The Florence and George Wise Observatory (IAU code 097) is an astronomical observatory owned and operated by Tel Aviv University. It is located west of the town of Mitzpe Ramon in the Negev desert near the edge of the Ramon Crater, and it is the only professional astronomical observatory in Israel.

Givatayim Observatory
The Givatayim Observatory is a public observatory that was founded in 1968 by the Israeli Astronomical Association and the Givatayim municipality. Activities These are some of the activities taking place in the observatory: * Public lectures and observations once or twice a week. * Israeli Astronomical Association lectures every Thursday. * Astronomy courses for adults and children * Hosting and promoting high school projects * Bachelor students and high school research activities (e.g., near Earth objects, variable stars, extrasolar planets) The observatory is placed on a hill (87m above sea level) inside a public park in Givatayim ( HaAliya HaShniya Garden). Givatayim is a town adjacent to Tel Aviv and part of the Greater Tel Aviv region. Because of this location, the sky is very bright and precludes observation of faint objects. Equipment * Meade 16-inch LX200 Schmidt-Cassegrain telescope. Mostly used for astrophotography. *Meade 12-inch LX200 Schmidt-Cassegrain ...

Six-Day War
The Six-Day War (, ; ar, النكسة, , or ) or June War, also known as the 1967 Arab–Israeli War or Third Arab–Israeli War, was fought between Israel and a coalition of Arab world, Arab states (primarily United Arab Republic, Egypt, Syria, and Jordan) from 5 to 10 June 1967. Escalated hostilities broke out amid poor relations between Israel and its Arab neighbours following the 1949 Armistice Agreements, which were signed at the end of the 1948 Arab–Israeli War, First Arab–Israeli War. Earlier, in 1956, regional tensions over the Straits of Tiran escalated in what became known as the Suez Crisis, when Israel invaded Egypt over the Israeli passage through the Suez Canal and Straits of Tiran, Egyptian closure of maritime passageways to Israeli shipping, ultimately resulting in the re-opening of the Straits of Tiran to Israel as well as the deployment of the United Nations Emergency Force (UNEF) along the Borders of Israel#Border with Egypt, Egypt–Israel border.

Star Party
A star party is a gathering of amateur astronomers the purpose of observing objects and events in the sky. Local star parties may be one-night affairs, but larger events can last a week or longer and attract hundreds or even thousands of participants. Many astronomy clubs have monthly star parties during the warmer months. Large regional star parties are held annually and are an important part of the hobby of amateur astronomy. A naturally dark site away from light pollution is typical. Participants bring telescopes and binoculars of all types and sizes and spend the nights observing astronomical objects such as planets, comets, stars, and deep-sky objects together. Astrophotography and CCD imaging are also very popular. At larger star parties, lectures, swap meets, exhibitions of home-built telescopes, contests, tours, raffles, and other similar activities are common. Commercial vendors selling a variety of astronomical equipment may also be present. As with other hobby ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
