Aintzira nebulosa (Messier
8) Sagittarius (Sagitarioa) konstelazioan kokaturik dagoen
izararteko hodei erraldoia da, nebulosa igorle eta HII eremu
bezala sailkatua. Bere tamaina 110 bider 50 argi-urtekoa da
gugandik 4000 eta 6000 argi-urte bitarteko distantzian kokaturik. Trifidoa
nebulosa -HII eremua- ezoiko nebulosa igorle (gorri-hori
eremua), erreflexu nebulosa (urdin eremua) eta nebulosa ilunen
(zati ilunak gorri-hori eremuan) konbinazioa da.
The Lagoon Nebula (Messier
8) is a giant interstellar cloud in the constellation
Sagittarius classified as an emission nebula and as an HII
region. Has actual dimension of 110 by 50 light years at
estimated 4000 to 6000 light-years away. The Trifid Nebula (Messier
20) is an H II region, an unusual combination of an open cluster,
an emission nebula (red-yellow portion), a reflection nebula (the
mainly blue portion) and a dark nebula (dark gaps in the
red-yellow portion).
