Antares, designated α Scorpii, is on average the fifteenth-brightest star in the night sky, the brightest object in the constellation of Scorpius. Distinctly reddish when viewed with the naked eye, Antares is a slow irregular variable star that ranges in brightness from apparent magnitude +0.6 to +1.6. Referred to as "the heart of the scorpion", Antares is flanked by σ Scorpii and τ Scorpii near the center of the constellation. Classified as a red supergiant of spectral type M1.5Iab-Ib, Antares is a red supergiant, a large evolved massive star. Its exact size remains uncertain, but if placed at the center of the Solar System it would reach to somewhere between the orbits of Mars and Jupiter, its mass is calculated to be around 12 times that of the Sun. Antares is the brightest, most massive, most evolved stellar member of the nearest OB association, the Scorpius–Centaurus Association. Antares is a member of the Upper Scorpius subgroup of the association, which contains thousands of stars with a mean age of 11 million years, about 170 parsecs from Earth.

Antares appears as a single star when viewed with the naked eye, but it is a binary star, with its two components called α Scorpii A and α Scorpii B. The brighter of the pair is the red supergiant, while the fainter is a hot main sequence star of magnitude 5.5. Α Scorpii is the star's Bayer designation. Antares has the Flamsteed designation 21 Scorpii, as well as catalogue designations such as HR 6134 in the Bright Star Catalogue and HD 148478 in the Henry Draper Catalogue; as a prominent infrared source, it appears in the Two Micron All-Sky Survey catalogue as 2MASS J16292443-2625549 and the Infrared Astronomical Satellite Sky Survey Atlas catalogue as IRAS 16262-2619. It is catalogued as a double star WDS J16294-2626 and CCDM J16294-2626. Antares is a variable star and is listed in the General Catalogue of Variable Stars but as a Bayer-designated star it does not have a separate variable star designation, its traditional name Antares derives from the Ancient Greek Ἀντάρης, meaning "rival to-Ares", due to the similarity of its reddish hue to the appearance of the planet Mars.

The comparison of Antares with Mars may have originated with early Mesopotamian astronomers. Some scholars have speculated that the star may have been named after Antar, or Antarah ibn Shaddad, the Arab warrior-hero celebrated in the pre-Islamic poems Mu'allaqat. In 2016, the International Astronomical Union organised a Working Group on Star Names to catalog and standardise proper names for stars; the WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN, which included Antares for the star α Scorpii A. It is now so entered in the IAU Catalog of Star Names. Antares is visible all night around May 31 of each year. Antares rises at dusk and sets at dawn as seen at the equator. For two to three weeks on either side of November 30 Antares is not visible in the night sky, because it is near conjunction with the Sun. In higher northern latitudes, Antares is only visible low in the south in summertime. Higher than 64º northern latitude, the star does not rise at all.

On the other side in the whole of Antarctica, the star is circumpolar as the whole continent is above 64º S latitude. Radial velocity variations were observed in the spectrum of Antares in the early 20th century and attempts were made to derive spectroscopic orbits, it became apparent that the small variations could not be due to orbital motion, were caused by pulsation of the star's atmosphere. In 1928, it was calculated that the size of the star must vary by about 20%. Antares was first reported to have a companion star by Johann Tobias Bürg during an occultation on April 13, 1819, although this was not accepted and dismissed as a possible atmospheric effect, it was observed by Scottish astronomer James William Grant FRSE while in India on 23 July 1844. It was rediscovered by Ormsby M. Mitchel in 1846, measured by William Rutter Dawes in April 1847. In 1952, Antares was reported to vary in brightness. A photographic magnitude range from 3.00 to 3.16 was described. The brightness has been monitored by the American Association of Variable Star Observers since 1945, it has been classified as an LC slow irregular variable star, whose apparent magnitude varies between extremes of +0.6 and +1.6, although near magnitude +1.0.

There is no obvious periodicity, but statistical analyses have suggested periods of 1,733 days or 1650±640 days. No separate long secondary period has been detected, although it has been suggested that primary periods longer than a thousand days are analogous to long secondary periods. Research published in 2018 demonstrated that Ngarrindjeri Aboriginal people from South Australia observed the variability of Antares and incorporated it into their oral traditions as Waiyungari. Antares is 4.57 degrees south of the ecliptic, one of four first magnitude stars within 6° of the ecliptic, so it can be occulted by the Moon. On 31 July 2009, Antares was occulted by the Moon; the event was visible in much of the Middle East. Every year around December 2 the Sun passes 5° north of Antares. Lunar occultations of Antares are common, depending on the 18.6-year cycle of the lunar nodes. The last cycle ended in 2010 and the next begins in 2023. Shown at right is a video of a reappearance event showing events for both components.

Antares can be occulted by the planets, e.g. Venus, but these events are rare; the last occultation of Antares by Venus took place on September 17, 525 BC.


Thttpd is an open source software web server from ACME Laboratories, designed for simplicity, a small execution footprint and speed. Thttpd is single-threaded and portable: it compiles cleanly on most Unix-like operating systems, including FreeBSD, SunOS 4, Solaris 2, BSD/OS, OSF/1, it has an executable memory size of about 50 kB. While it can be used as a simplified replacement to more feature-rich servers, it is uniquely suited to service high volume requests for static data—for example as an image hosting server; the first "t" in thttpd stands for turbo, or throttling. Thttpd has a bandwidth throttling feature which enables the server administrator to limit the maximum bit rate at which certain types of files may be transferred. For example, the administrator may choose to restrict the transfer of JPEG image files to at most 20 kilobytes per second; this prevents the connection from becoming saturated so that the server will still be responsive under heavy load, with the tradeoff that file transfer speed is reduced.

Isbjerget is a residential building in the Aarhus Docklands neighborhood in Aarhus, Denmark. It is situated on the waterfront on Mariane Thomsens Gade and was finished in 2013 after three years of development; the building was designed by four architectural firms, the Danish CEBRA and JDS Architects, French Louis Paillard and Dutch SeARCH, was funded by the Danish pension fund PensionDanmark. Isbjerget was the first project to be completed on the former industrial port area, being developed into a new residential and commercial neighborhood after the Port of Aarhus was moved to new facilities to the south of the city center; the building complex consists of four buildings with 208 apartments between 55 m2 and 200 m2 both rented and owned. The apartments are either in two stories, double in height or with shifted floor plans, catering to different needs; the buildings are up to ten floors tall but vary in height, with the shortest building closest to the waterfront and the tallest further back.

The complex is designed and modeled after floating icebergs in the north Atlantic, both in shape and color. The buildings are divided and crisscrossed into smaller units with steep crooked roofs, to ensure that all inhabitants have ideal views of the sea. Visually, the buildings display shifting, irregular facades; the buildings have balconies made of blue glass. In 2013, Isbjerget was awarded the Best Residential Development award at the French architects conference MIPIM. In 2015 it was given the Best Housing award by the ArchDaily website, which caters to architects and designers. Architecture pictures of Isbjerget at

Petropavlovsk-Kamchatsky Airport

Yelizovo Airport is an airport located in Petropavlovsk-Kamchatsky, Kamchatka Krai. Its 3,400 m runway is long enough to accommodate a loaded Ilyushin Il-96 or Boeing 707 aircraft; the main apron contains 34 parking spaces, 18 of which can service large wide-body airliners, such as Ilyushin IL-96. The main military operating unit is the 865th Fighter Aviation Regiment, which operates Mikoyan MiG-31 interceptor aircraft. Naval operations have taken place here, most notably with the 317th Separate Composite Aviation Regiment operating Tupolev Tu-16R aircraft as late as 1992, Beriev Be-12 and Tupolev Tu-95MS aircraft with unidentified units. Recent Google Earth high-resolution imagery revealed that the base continues to serve as an important military focal point, with 33 MiG-31 aircraft dispersed throughout the airfield and a large number of turboprop transports and helicopters; the 865th Fighter Aviation Regiment was activated as an Assault Aviation regiment in 1939. After two redesignations, it was renamed the 410th Assault Aviation Regiment in October 1944.

It has been based at the base since 1945. In April 1949 it was renamed again as the 865th Fighter Aviation Regiment, was transferred to the Soviet Air Defence Forces, renamed the 865th Fighter Aviation Regiment PVO. From April 1986 it was assigned to the 6th Air Defence Division, 11th Independent Air Defence Army, PVO, until its reassignment to the Pacific Fleet. On 1 July 1998 it was transferred to the Soviet Pacific Fleet, it was equipped with Sukhoi Su-15s from 1974 to 1985 and was reequipped with MiG-31s from 1985. Airliner World ran a feature in their August 2008 issue on'Aviation in Kamchatka,' leading with descriptions of Yelizovo, it confirmed the basing of 865 IAP and 317 OSAP, commented'the numbers of local military aircraft in open storage do catch the eye'...'difficult to assess whether the aircraft are active or not.' One photo showed a total of eleven MiG-31s parked together in two groups directly in front of two hardened aircraft shelters built into the hillside. On 1 April 2012, reconstruction began on runway 16R/34L in order to widen it to 45 m and extend it by 900 m to 3,400 m in order to better accommodate larger planes.

Terminal and apron improvements are included in the project. In August 2017, Airports of Regions won a contest to complete the construction of a new passenger terminal at the airport; the construction will commence in 2018 and is planned to be completed by 2021.

Kosmos 70

Kosmos 70 known as DS-A1 No.7 was a technology demonstration satellite, launched by the Soviet Union in 1965 as part of the Dnepropetrovsk Sputnik programme. Its primary mission was to demonstrate technologies for future Soviet military satellites, it conducted radiation experiments. It was launched aboard a Kosmos-2I 63S1 rocket, flying Site 86/1 at Kapustin Yar; the launch occurred at 06:30 UTC on 2 July 1965. Kosmos 70 was placed into a low Earth orbit with a perigee of 223 kilometres, an apogee of 1,176 kilometres, 48.8 degrees of inclination, an orbital period of 98.8 minutes. It decayed on 18 December 1966. Kosmos 70 was the last of seven DS-A1 satellites to be launched, of which four; as with earlier DS-A1 satellites, the technological experiments aboard Kosmos 70 were tests of communications and navigation systems which were used on the GLONASS system. 1965 in spaceflight

Amala (mythology)

Amala is a mythological giant who supports the world in the mythology of the Tsimshian, Skidegate, Kaigani and Tlingit Native Americans. He supports the Earth, he receives an annual application of wild duck-oil to his muscles from a servant which brings relief to his muscles. The belief is that when all the ducks are hunted out, there will no longer be any duck-oil available in the world. At this point, Amala dies and the world topples off the pole and comes to an end; the name Amala refers to his being dirty and means “smoke hole.” Amala is said to be the youngest child in a family, physically weak and lazy. He suffers mistreatment from everybody. In many variants of the myth, Amala sleeps in his urine. Late in his life he attains supernatural strength in secret and becomes a handsome, powerful young man who performs many daring feats and turns savior and protector for his relatives against their enemies; the concluding feat of his life is to succeed a dying chief on an island in the Southwest sea in the task of holding the Earth up.

The dying chief hears of Amala's various exploits and, calls the hero. When Amala arrives, the chief hands over the long pole upon; some versions of the myth state that the chief places the pole on Amala's chest, while some versions hold that the pole is held behind Amala's back. A servant relieves Amala's muscles with yearly application of spoonfuls of duck grease and wild-duck oil which help Amala to keep the world spinning. There is a possibility that the myths about Amala and similar heroes of Native American mythology were influenced by the tales of Cinderella and Atlas - the titan who carries the world on his shoulder in Greek mythology, introduced into Native American culture from Europe. There is a similarity between Cinderella and Amala in that both sleep in ashes and both are abused by their tribe or family; the storyline of Amala - the despised member of the tribe who overcomes adversity and rises to be a hero among his people, may be a combination of elements of the downtrodden and derided hero or heroine, such as Cinderella, the hero of the Atlas-type who dwells in the underworld.
