Oriontågen
Oriontågen - en stjernefabrik i universet
Den centrale del af Oriontågen
Oriontågen (M 42 og NGC 1976) er en sky af gas og støv i verdensrummet. I denne tåge opstår der nye stjerner.
Oriontågen (M42) findes midt i stjernebilledet Orion, som den midterste "stjerne" i "sværdet" under Orions Bælte. Afstanden til Oriontågen er ca. 450 parsec = ca. 1.470 lysår. Hvad der med det blotte øje ser ud til at være en stjerne, er i virkeligheden et lille belyst udsnit af en gigantisk diffus molekylesky ved navn Orion A Complex eller Orion Molecular Cloud 1 (OMC1). Dette udsnit belyses af Trapezet, 5 unge og massive stjerner (hver på 15-30 solmasser), som ser ud til at forme et trapez.

Orion Nebula - Hubble 2006 mosaic 18000.jpg
In one of the most detailed astronomical images ever produced, NASA/ESA's Hubble Space Telescope captured an unprecedented look at the Orion Nebula. ... This extensive study took 105 Hubble orbits to complete. All imaging instruments aboard the telescope were used simultaneously to study Orion. The Advanced Camera mosaic covers approximately the apparent angular size of the full moon.
