Located in the Perseus Arm of the Galaxy, the Heart and Soul Nebulae are located in
a region of active star formation containing many young clusters of stars.
These dramatic objects are
regions of active star formation where the hot young stars are causing the surrounding hydrogen gas to glow red.
Reddish nebulae reveal
regions of active star formation, where young, hot stars heat up nearby gas clouds.
In galaxies like the Milky Way, dense gas traced by HCN but composed mainly of hydrogen molecules is always associated with
regions of active star formation.
The H - alpha line emission, which indicates
regions of active star formation, is highlighted in blue (SINGG Survey; Meurer +2006).

Like most dark nebulae, Lupus 3 is an
active star formation region, primarily composed
of protostars and very young
stars.
Some, like the Milky Way, are flat disks with arcing spiral arms and
regions of dense interstellar gas, called nebulae, which are
active sites
of star formation.
The overabundance
of these failed
stars and low - mass planetary bodies has led the team to believe that there may be fewer
active star formation regions at work within the Orion Nebula than had previously been believed.
