A composite Hubble image from 1995 shows this process occurring in elephant trunks in the Eagle Nebula that were dubbed the Pillars of Creation.
BzK photometry is used to classify galaxies by this phenomenon, which, along with redshift, characterizes Lyman-break galaxies. This process requires a quantity to exceed the square root of 3-pi-gamma-kT all over 32 big-G rho-sub-zero mu m-sub-p, which is the maximum radius at which the time for a pressure gradient exceeds free-fall time. The Bonnor–Ebert equation more accurately models the mass within that Jeans length. This process produces jet-like Herbig–Haro objects. A composite Hubble image from 1995 shows this process occurring in elephant trunks in the Eagle Nebula that were dubbed the Pillars of Creation. Galaxies in which it is common include the aptly named Baby Boom Galaxy. For 10 points, name this process common in starburst galaxies, in which molecular clouds collapse to the point at which nuclear fusion starts.
