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.
Meet Mario Vargas, a technical specialist III at the U.S. National Science Foundation National Radio Astronomy Observatory’s Central Development Laboratory.
Meet Sonia Duffau, head of Education and Public Outreach (EPO) for the U.S. National Radio Astronomy Observatory in Chile.
A team of astronomers found that in typical galaxies, pressure from ionized gas generated by newly formed stars drives the expansion of star-forming regions. However, whether these regions continue to grow or stall depends strongly on their surrounding environment.
