Orion is one of the largest constellations in the sky. It is supposed to look like the warrior Orion from Greek mythology. The constellation has other names in different cultures: it is mentioned under a Hebrew name in the Book of Job. The constellation has a clear hour-glass shape with "Orion's Belt" in the centre. That part is made up of three bright stars (Alnitak, Alnilam, Mintaka) in line. The Orion constellation has 81 visible stars, including some of the brightest and most important stars in the night sky. Rigel is the brightest star in it, and Betelgeuse is a huge, rather unstable red supergiant. The constellation includes a series of starburst nebulae where new stars are forming. The whole group of nebulae is known as the Orion complex. The complex is 1,500 to 1,600 light-years away, and hundreds of light-years across. It includes The Orion nebula M42 M43 IC 434 The Horsehead nebula Barnard's Loop M78, a reflection nebula NGC 1999 NGC 2175 NGC 2174 Orion molecular cloud Flame nebula Train Wreck Cluster...

Scorpius, halaber Eskorpioia, astrologian, zodiakoko zortzigarren zeinua da. Zeinuak suntsiketa sinbolizatzen du eta irudian eskorpioia agertzen da irudikatuta. Pisces eta Cancerrekin batera ura elementuari dagokio. Martek eta Plutonek zuzentzen dute eta aurrez aurreko zeinua Taurus du. Urriaren 23a eta azaroaren 22a bitartean jaiotzen direnak izaten dira zeinu honetakoak. Mitologia Konstelazioaren jatorria Orionen elezaharretik dator. Bertsioetako batek kontatzen duenez, jeloskortasunak eragindako haserrealdi batean Orionek begiak atera zizkion bere buruari eta itsututa zegoela eskorpioi batek ziztatu zion heriotza eraginez. Jainkoek bai Orion eta bai eskorpioia ere zerura igo zituzten. Bakoitza mutur batean kokatu zituzten, horrela, eskorpioia horizontean agertzen denean, Orion ezkutatu egiten da, heriotza eragin zioenarengandik ihes eginez. Bertsio zabalago batek Orion Artemis (Ilargia) bortxatzen ahalegindu zela dio. Artemisek eskorpioi baten laguntza eskatu zuen Orion erraldoiaren eskuetatik ihes egiteko. Eskorpioiak Orion hil egin zuen eta horregatik Artemisek zeruan jarri zuen eskorpioia. ...

We investigate the intrinsic stellar populations (estimated total numbers of OB and pre-main-sequence stars down to 0.1 Mo) that are present in 17 massive star-forming regions (MSFRs) surveyed by the MYStIX project. The study is based on the catalog of >31,000 MYStIX Probable Complex Members with both disk-bearing and disk-free populations, compensating for extinction, nebulosity, and crowding effects. Correction for observational sensitivities is made using the X-ray Luminosity Function (XLF) and the near-infrared Initial Mass Function (IMF)--a correction that is often not made by infrared surveys of young stars. The resulting maps of the projected structure of the young stellar populations, in units of intrinsic stellar surface density, allow direct comparison between different regions. Several regions have multiple dense clumps, similar in size and density to the Orion Nebula Cluster. The highest projected density of ~34,000 stars/pc^2 is found in the core of the RCW38 cluster. Histograms of surface density show different ranges of values in different regions, supporting the conclusion of Bressert et al. (2010, B10) that no universal surface-density threshold can distinguish between clustered and distributed star-formation. However, a large component of the young stellar population of MSFRs resides in dense environments of 200-10,000 stars/pc^2 (including within the nearby Orion molecular clouds), and we find that there is no evidence for the B10 conclusion that such dense regions form an extreme "tail" of the distribution. Tables of intrinsic populations for these regions are used in our companion study of young cluster properties and evolution.

Un stella o astere o astro es un corpore celeste de plasma in equilibrio hydrostatic que genera energia in su interior pro medio de fusion thermonuclear. Le energia generate radia al spatio in forma de radiation electromagnetic e neutrinos. Un grande parte de lo cognoscite super le stellas veni ab le studio del nebulosas. Le stellas nasce in nebulosas como le Nebulosa de Orion, in vice alteres, como le Nebulosa del Cancere, son le restos de un stella que ha explodite. Quando un stella mori devolve le material que lo forma al spatio interestellar, isto include elementos pesante que plus tarde formara nove stellas o planetas. Permulte stellas son attrahite gravitationalmente a altere stellas formante systemas binari. Le stellas non es distribuite uniformemente in le universo, ma, typicamente, son aggruppate in galaxias. Un galaxia gigante typic (como le nostre) contine centos de milles de milliones de stellas. Le Sol es considerate un stella prototypic, non proque illo es special in alicun senso, plus tosto quia illo es le plus proxime al Terra e per lo tanto le plus studiate. Le majoritate del characteristicas del stellas es mesurate in unitates...
