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 Board appoints new Director
After a competitive selection process that started in January 2017, the ALMA Board has appointed Dr. Sean Dougherty to lead the Observatory as the new ALMA Director for 5 years, starting by the end of the first quarter of 2018.
Sean is currently the Director of the Dominion Radio Astrophysical Observatory, Canada’s national radio astronomy facility, run by NRC Herzberg Astronomy and Astrophysics. He has served as a member of the ALMA Board representing North America for 4 years and was the chair of the ALMA Budget Committee for the last 2 years.
Dr. Sean Dougherty received his PhD in Astrophysics from University of Calgary, Canada, in 1993 following his Bachelor degree in Mathematics and Physics from University of Nottingham, England. He has over 20 years of science and engineering management experience in radio astrophysics, from management and representation of Canada’s contributions to international radio astronomy facilities and R&D projects, to leadership of major science and engineering activities at the Dominion Radio Astrophysical Observatory (DRAO). He led the design and construction of the WIDAR correlator for the JVLA, and is currently leading the international consortium designing the correlator-beam former for the SKA.
The Board extends its appreciation to Dr. Stuartt Corder, who has served and will continue to serve as the ALMA acting Director during the succession process. The details of the transition are yet to be finalized, but we are confident that there will be a smooth handover of the the organization’s management from Stuartt to Sean in 2018. The ALMA Board believes that our past and future success has been and will be the result of the leadership and hard work of many very gifted, talented and dedicated individuals and asks the ALMA Staff and management to welcome and support Dr. Dougherty in this new role.”
