Using the powerful Atacama Large Millimeter/submillimeter Array (ALMA), their team observed— for the first time ever— a narrow, spiral-shaped streamer of gas guided by magnetic fields, channeling matter from the surrounding cloud of a star-forming region in Perseus, directly onto a newborn binary star system.

Astronomers Discover Fastest-Evolving Radio Signals Ever Observed from Black Hole Tearing Apart Star
An international team of astronomers has discovered the first radio-bright tidal disruption event (TDE) occurring outside a galaxy’s center using the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) Very Large Array (NSF VLA) and Atacama Large Millimeter/submillimeter Array (ALMA), along with several partner telescopes.
First-ever Detection of “Heavy Water” in a Planet-forming Disk
The discovery of ancient water in a planet-forming disk reveals that some of the water found in comets—and maybe even Earth—is older than the disk’s star itself, offering breakthrough insights into the history of water in our Solar System.
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
