Mystery of Star Formation Revealed by Hearts of Molecular Clouds

Data from the World’s Largest Radio Telescopes Holds Clues

Research on the far edge of galaxy M83 reveals unusual star formation in an extreme environment. This area, outlined in yellow, is shown in data from several different instruments. From left to right: optical image from CTIO, ultraviolet image from GALEX, HI 21cm image from VLA and GBT, and CO(3-2) image from ALMA. In this last image, the star-forming “hearts” of molecular clouds, circled with white, are shown.

Astronomers Accidentally Discover Dark Primordial Galaxy

Could Be the Faintest Galaxy Found to Date

Artist depiction of hydrogen gas observed in galaxy J0613+52.  The colors indicate the likely rotation of the gas relative to the observer (red=away, blue=toward). This image was made using a starfield from STScI POSS-II with additional illustration by NSF/GBO/P.Vosteen.

DiSCo-Data: Dynamics in Star-forming COres

The DiSCo survey will address a key open question in star formation: the origin and distribution of angular momenta of star-forming cores. Our broad statistical approach is essential to understanding the range of intrinsic behavior, the statistically most common behaviors, and how those behaviors correlate with stellar outcome and environment. By characterizing the detailed kinematics of more than 100 cores, this GBT Large Program will address the angular momentum question with a statistically broad sample and provide many opportunities for ancillary science by the star formation community worldwide.
