WebHII regions are concentrated within the nuclear ring, the bright inner ring, and the outer arms, but that there was little emission from the region between the nuclear and inner rings. The same was found for the inner and nuclear rings of NGC 5728by Rubin (1980). Figure 41. in NGC 1433(right), compared to a red continuum image (left), from WebH II Regions and Related Topics ...

WebNestled in the center of M42 is a group of stars, known as the Trapezium, which have formed from the gas in the nebula. The stars of the Trapezium are young blue stars. It is their energy which makes the nebula glow. The Orion nebula is more or less circular in shape, and it glows with a characteristic red color. All HII regions have this color. WebThe red nebular region directly above the brightest star in this three-color composite image is the high mass star formation complex known as K3-50. The cluster is located in the constellation Cygnus at a distance of about 8700 pc (28000 light years). ... The galactic HII regions Sharpless 254 through 258. The molecular cloud associated with ...
WebThe evolution to UC HII regions begins in giant molecular clouds that provide the natal material for prestellar cores that evolve into hot cores, the precursors of UC HII regions. The properties of each evolutionary phase are reviewed, with particular emphasis on those of hot cores. The observed properties of UC HII regions and their ...

WebJun 28, 2014 · You probably recall that emission nebulae are commonly referred to as "HII regions". Electrons that have been stripped from the hydrogen atoms can rejoin atoms and resume the process of Balmer decays all over again. This ongoing process is what gives us the reddish-colored nebulae. So that's the technical explanation. You were warned!
