描述W5 cropped.jpg |
English: From the source site, courtesy of NASA/JPL-Caltech: Generations of stars can be seen in this new infrared portrait from NASA's Spitzer Space Telescope. In this wispy star-forming region, called W5, the oldest stars can be seen as blue dots in the centers of the two hollow cavities (other blue dots are background and foreground stars not associated with the region). Younger stars line the rims of the cavities, and some can be seen as pink dots at the tips of the elephant-trunk-like pillars. The white knotty areas are where the youngest stars are forming. Red shows heated dust that pervades the region's cavities, while green highlights dense clouds.
W5 spans an area of sky equivalent to four full moons and is about 6,500 light-years away in the constellation Cassiopeia. The Spitzer picture was taken over a period of 24 hours.
Français : Traduction française de la légende originale de la NASA/JPL-Caltech : Image infrarouge du télescope spatial Spitzer représentant la région W5, une zone de formation d'étoiles couvrant la surface de quatre pleines lunes. Plusieurs générations d'histoire peuvent être vues sur cette image. Les étoiles les plus vieilles sont visibles sous la forme de points de lumière bleue au centre des deux cavités vides (Les autres points bleus sont des étoiles plus proches ou plus éloignées que W5). Des étoiles plus jeunes sont sur le bord de ces cavités, et d'autres sont visibles sous la forme de points roses au sommet des piliers. Les étoiles les plus jeunes sont en train de se former dans les zones grumeleuses blanches. Le rouge marque la poussière chaude qui occupe les cavités de cette région, et le vert marque les nuages denses. |

Čeština: Na této nové infračervené fotografii ze Spitzerova vesmírného dalekohledu je možno vidět mnoho generací hvězd Dansk: Infrarødt billede fra NASAs Spitzer-rumteleskop af stjernedannelsestågen W5 i stjernebilledet Cassiopeia. W5 ligger omkring 6.500 lysår fra Jorden og dækker et område af himlen, som svarer til fire fuldmåner.

Français : Image infrarouge du télescope spatial Spitzer représentant la région W5, une zone de formation d'étoiles couvrant la surface de quatre pleines lunes. Italiano: Immagine all'infrarosso in falsi colori ripresa dal Telescopio spaziale Spitzer della regione di formazione stellare di Cassiopea W5. Nederlands: infraroodafbeelding van de emissienevel W5 (IC 1871 of "zielnevel") in het H-II-gebied in het sterrenbeeld Cassiopeia gemaakt door de Spitzer Space Telescope van de Nasa. W5 ligt op ongeveer 6.500 lichtjaren van de Aarde verwijderd, omspant een gebied ter grootte van vier volle manen en vormt een stervorminggebied. De foto, die werd gemaakt over een periode van 24 uur, vormt een van de beste bewijzen voor de theorie van de 'getriggerde stervorming'; een bepaalde oorzaak die leidt tot de zwaartekrachtinstorting van een moleculaire wolk.
