... 2016 February 16 . Star Forming Region S106 . ... Explanation: Massive star IRS 4 is beginning to spread its wings. Born only about 100,000 years ago, material streaming out from this newborn star has formed the nebula dubbed Sharpless 2-106 Nebula (S106), featured here . ... S106 gas near IRS 4 acts as an emission nebula as it emits light after being ionized , while dust far from IRS 4 reflects light from the central star and so acts as a reflection nebula . ...

... The highly obscured cases in our sample are generally the bright, central regions of galaxies with high overall attenuation but are not otherwise remarkable. ... The small fraction of highly obscured regions seen in this sample of normal, star-forming galaxies suggests that on 500 pc scales the timescale for significant dispersal or breakup of nearby, optically thick dust clouds is short relative to the lifetime of a typical star-forming region. ...

It is especially hard to explain this process of star birth in some spiral galaxies. ... Targets include both star clusters and galaxies, and star formation rates seen range from the starburst galaxy M82 (the Cigar Galaxy) which is creating about ten new stars in its core alone every year to the much less fecund star producer NGC 2841. ...

NGC 5128 is the closest example of a giant early type (elliptical or S0) galaxy. Although often dubbed as a peculiar elliptical galaxy since it has a dust lane with recent star formation and an active galactic nucleus, the majority of early type galaxies have similar structures as revealed by recent surveys. ...
