Herschel links star formation to sonic booms
ESA’s Herschel space observatory has revealed that nearby interstellar clouds contain networks of tangled gaseous filaments. Intriguingly, each filament is approximately the same width, hinting that they may result from interstellar sonic booms throughout our Galaxy.
Characterizing interstellar filaments with Herschel in IC5146
A new publication from the Gould Belt survey programme (Arzoumanian et al.). Here is the abstract: We provide a first look at the results of the Herschel Gould Belt survey toward the IC5146 molecular cloud and present a preliminary analysis of the filamentary structure in this region.
