Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have captured the first direct, high-resolution images of a magnetic field wrapped tightly around the outflow of gas streaming away from a forming star — evidence that solves a decades-old puzzle about how young stars sculpt the powerful jets that form them.

A Trillion Mile Cosmic Stream of Gas Feeds GW Orionis
A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory is a partner, has captured a massive stream of gas—one trillion miles, or .2 light years long—feeding the young triple-star system GW Orionis.
NSF NRAO radio observations help rule out a relativistic jet in rare stellar explosion
Astronomers studying a rare stellar explosion first spotted as a brief burst of X-rays used radio observations to help show that the dying star did not produce the powerful jet often associated with gamma-ray bursts.
ALMA Reveals Cradles of Dense Cores: the Birthplace of Massive Stars
Taiwanese research team used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a large molecular gas clump — named G33.92+0.11 — where a cluster of massive stars is forming. ALMA revealed, in unprecedented detail, the fine structure of the molecular gas at the center of the region, where two surprisingly large molecular gas arms about 3 light-years across, appear to be spiraling around two massive molecular cores.
These results show that the large molecular arms are indeed the cradles of dense cores, which are current or future birthplaces of massive stars. These results represent a crucial step forward in the understanding of how mass distributes to form both massive cores and massive stars.
Details on this result can be found here.
