An article published in the journal “The Astrophysical Journal Supplement Series” describes the results of the CARMA-NRO Orion Survey, a high-resolution mapping of the molecular cloud called Orion A, one of the two giant molecular clouds in the Orion molecular cloud complex. A team of astronomers combined the observations of the CARMA and NRO radio telescopes to map the stars but also the gas movements inside the cloud.
