ALMA Reveals Teenage Years of New Worlds
The ALMA survey to Resolve exoKuiper belt Substructures (ARKS), using the Atacama Large Millimeter/submillimeter Array (ALMA), has produced the sharpest images ever of 24 debris disks, the dusty belts left after planets finish forming. These disks are the cosmic equivalent of the teenage years for planetary systems—somewhat more mature than newborn, planet-forming disks, but not yet settled into adulthood.
The NSF Very Large Array Helps Reveal Record-Breaking Stream of Super-Heated Gas from Nearby Galaxy
New radio images from the the U.S. National Science Foundation Very Large Array trace a pair of powerful plasma jets launched by galaxy VV 340a’s central supermassive black hole, which appear to be driving hot coronal gas out of the galaxy and shutting down future star formation.
International Astronomical Union (IAU) General Assembly
Every year, astronomers from all around the globe gather for a couple of weeks at the IAU General Assembly to discuss their discoveries and observations, and to exchange ideas and challenges facing astronomy. This year the assembly is taking place in Honolulu, Hawaii. I had the privilege to give opening remarks this past Tuesday. As I said in my remarks, “it is a great honor to represent the Obama Administration at this historic event.”
NSF is one of the world’s leading institutions in astronomy. For decades, NSF-funded researchers have been exploring the most intriguing mysteries of the heavens. We hope to continue doing so!


Great catching up with the National Solar Observatory (NSO) and NSF solar astronomy program officer Dave Boboltz. One of NSO’s major projects is the NSF-funded Daniel K. Inouye Solar Telescope on Haleakala, Hawaii. This telescope will provide new insights into solar phenomena, including solar storms. Photo credit: NSF

With the recent announcement about Breakthrough Listen, I enjoyed talking with National Radio Astronomy Observatory’s Tony Beasley about how NSF-funded radio astronomy will play a key role. Photo credit: NSF
