There are many myths and legends about the origin of the Milky Way, the crowd of stars that makes a distinctive bright streak across the night sky.
Ancient Armenian mythology called the Milky Way the "Straw Thief's Way". According to legend, the god Vahagn stole some straw from the Assyrian king Barsham and brought it to Armenia during a cold winter. When he fled across the heavens, he spilled some of the straw along the way.
The Khoisan people of the Kalahari desert in southern Africa say that long ago there were no stars and the night was pitch black. A girl, who was lonely and wanted to visit other people, threw the embers from a fire into the sky and created the Milky Way.
A Cherokee folktale tells of a dog who stole some cornmeal and was chased away. He ran away to the north, spilling the cornmeal along the way. The Milky Way is thus called ᎩᎵ ᎤᎵᏒᏍᏓᏅᏱ (Gili Ulisvsdanvyi) "The Way the Dog Ran Away".
Peoples in Eastern Asia believed that the hazy band of stars was the "Silvery River" of Heaven (Chinese: 銀河, Korean: eunha and Japanese: ginga). In one story, the stars Altair and Vega were said to be two lovers who were allowed to meet only once a year on the seventh day of the seventh month, when a flock of magpies and crows formed a bridge over the galactic river. That day is celebrated as Qi Xi, the Seventh Night (Chinese: 七夕, Korean: chilseok and Japanese: tanabata).
A galaxy is an astronomical system that consists of a large number of stars and other matter.

The map (Araschnia levana) is a butterfly of the Nymphalidae family. It is common throughout the lowlands of central and eastern Europe, and is expanding its range in Western Europe.
In the UK this species is a very rare vagrant, but there have also been several unsuccessful – and now illegal – attempts at introducing this species over the past 100 years or so: in the Wye Valley in 1912, the Wyre Forest in the 1920s, South Devon 1942, Worcester 1960s, Cheshire 1970s, South Midlands 1990s. All these introductions failed and eggs or larvae have never been recorded in the wild in the UK. (Under the Wildlife and Countryside Act 1981 it is now illegal to release a non-native species into the wild.)
The map is unusual in that its two annual broods look very different. The summer brood are black with white markings, looking like a miniature version of the white admiral and lacking most of the orange of the pictured spring brood.
The eggs are laid in long strings, one on top of the other, on the underside of stinging nettles, the larval foodplant. It is thought that these strings of eggs mimic the flowers of the nettles, thereby evading predators. The larvae feed gregariously and hibernate as pupae.
In computing, associative containers refer to a group of class templates in the standard library of the C++ programming language that implement ordered associative arrays. Being templates, they can be used to store arbitrary elements, such as integers or custom classes. The following containers are defined in the current revision of the C++ standard: set
, map
, multiset
, multimap
. Each of these containers differ only on constraints placed on their elements.
The associative containers are similar to the unordered associative containers in C++ standard library, the only difference is that the unordered associative containers, as their name implies, do not order their elements.
map
and set
each key must be unique. multimap
and multiset
do not have this restriction.map
and multimap
each element is composed from a key and a mapped value. In set
and multiset
each element is key; there are no mapped values.USA or U.S.A. usually refers to the United States of America, a country in North America.

USA-135, also known as GPS IIA-19, GPS II-28 and GPS SVN-38, is an American navigation satellite which forms part of the Global Positioning System. It was the last of nineteen Block IIA GPS satellites to be launched.
USA-135 was launched at 00:30:00 UTC on 6 November 1997, atop a Delta II carrier rocket, flight number D249, flying in the 7925-9.5 configuration. The launch took place from Launch Complex 17A at the Cape Canaveral Air Force Station, and placed USA-135 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37XFP apogee motor.
On 13 December 1997, USA-135 was in an orbit with a perigee of 19,912 kilometres (12,373 mi), an apogee of 20,449 kilometres (12,706 mi), a period of 717.9 minutes, and 54.9 degrees of inclination to the equator. It broadcasts the PRN 08 signal, and operates in slot 3 of plane A of the GPS constellation. The satellite has a mass of 1,816 kilograms (4,004 lb). It had a design life of 7.5 years, but it actually remained in service until October 30, 2014.
USA-200, also known as NRO Launch 28 or NROL-28, is an American signals intelligence satellite, operated by the National Reconnaissance Office. Launched in 2008, it has been identified as the second satellite in a series known as Improved Trumpet, Advanced Trumpet, or Trumpet follow-on; a replacement for the earlier Trumpet series of satellites.
USA-200 was launched by an Atlas V carrier rocket, flying in the 411 configuration, operated by United Launch Alliance. The rocket was the first Atlas V to launch from Vandenberg Air Force Base, flying from Space Launch Complex 3E. Liftoff occurred at 10:02 UTC (03:02 PDT) on 13 March 2008. It was identified as NRO Launch 28, and was the thirteenth flight of an Atlas V. The rocket had the tail number AV-006.
The satellite's orbit and mission are officially classified, however like most classified spacecraft it has been located and tracked by amateur observers. It is in a Molniya orbit with a perigee of 1,111 kilometres (690 mi), an apogee of 37,580 kilometres (23,350 mi), and 63.5 degrees of inclination. In addition to its SIGINT payload, USA-200 also carries two secondary instruments; the SBIRS-HEO-2 missile detection payload as part of the Space-Based Infrared System programme, and NASA's TWINS-2 or TWINS-B magnetospheric science instrument as part of the TWINS programme.
A million stars above me
only one life to count them all
A thousand years of wishes for a simple man
Milky Way
Look as far as the eye can see
Try, if you can, to understand
I'm just a man of a planet in a galaxy
Milky Way
** We are children of the universe
We are the first
One by one we seek to reach the stars
The future's ours
People are people
We all live to play this game
We turn on the wheel by stairways to the stars
Milky Way
** Repeat
* Repeat
