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.
Astronomy EPO and STEM Education: The Perfect Couple
Presented at the NSF Pavilion in the Exhibit Hall of the IAU General Assembly on Tuesday, August 11, 2015
Abstract: Astronomy provides tremendous opportunity for interdisciplinary learning as well as learning across a variety of formal and informal settings. The recent focus on STEM education globally can stimulate new ways of thinking about Astronomy EPO and delivery models that lead to greater impact. This presentation will focus on the integration of astronomy and STEM, and highlight several AUI efforts.
Bio: Tim has been a leader in STEM education for more than 20 years, and served as lead editor and author for the recently released book, Einstein Fellows: Best Practices in STEM Education. Prior to his role with AUI and efforts with NRAO, he was an Einstein Fellow at the National Science Foundation, taught astronomy and earth sciences at the high school and college levels for more than 20 years, and served as K–12 Science Coordinator for Oil City Schools. He has led numerous educator-training programs throughout the United States and abroad, and has developed a wide variety of astronomy experiences for learners of all ages. He is an active amateur astronomer, and has directed many astronomy outreach and PR efforts, and led several observatory design and construction projects for the Oil Region Astronomical Society and their partners. Tim currently serves as PI for two NSF supported programs, the Chile-US Astronomy Education Outreach Summit, and the Astronomy in Chile Educator Ambassadors Program (ACEAP).
