ALMA Gets Front-Row Seat to an Ongoing Star-Formation Standoff in the Large Magellanic Cloud
ALMA Gets Front-Row Seat to an Ongoing Star-Formation Standoff in the Large Magellanic Cloud
June 15, 2022 at 9:15 am | News Release

While using the Atacama Large Millimeter/submillimeter Array (ALMA) to observe large star-forming regions in the Large Magellanic Cloud (LMC), scientists discovered a turbulent push-and-pull dynamic in the star-forming region, 30 Doradus. Observations revealed that despite intense stellar feedback, gravity is shaping the molecular cloud, and against scientific odds, is driving the ongoing formation of young, massive stars.

Undergraduate Researcher Captures Young Galaxy’s “Coming of Age” and Finds Evidence That Early Galaxies May Be Bigger and More Complex Than We Thought

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA)— an international observatory co-operated by the US National Science Foundation’s National Radio Astronomy Observatory (NRAO)—have observed a significant amount of cold, neutral gas in the outer regions of the young galaxy A1689-zD1, as well as outflows of hot gas coming from the galaxy’s center. These results may shed light on a critical stage of galactic evolution for early galaxies, where young galaxies begin the transformation to be increasingly like their later, more structured cousins.

Scientists on the Hunt for Planetary Formation Fossils Reveal Unexpected Eccentricities in Nearby Debris Disk
June 14, 2022 at 9:15 am | News Release

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have imaged the debris disk of the nearby star HD 53143 at millimeter wavelengths for the first time, and it looks nothing like they expected. Based on early coronagraphic data, scientists expected ALMA to confirm the debris disk as a face-on ring peppered with clumps of dust. Instead, the observations took a surprise turn, revealing the most complicated and eccentric debris disk observed to date.

NRAO Honors Pride Month: We Are {ALL} Made of Star Stuff
June 1, 2022 at 9:00 am | Announcement

The NRAO has made a visible change to our logo for Pride month, because we want to send the clear message that NRAO values our current and future LGBTQIA+ colleagues, friends, and family members. We send this same message internally by taking seriously our obligation to create and maintain an environment that is safe, secure, and welcoming.
