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.
Radio Telescopes Uncover ‘Invisible’ Gas Around Record-Shattering Cosmic Explosion
Astronomers using the U.S. National Science Foundation Very Large Array and the Atacama Large Millimeter/submillimeter Array have revealed a dense cocoon of gas around one of the most extreme cosmic explosions ever seen, showing that a ravenous black hole ripped apart a massive star and then lit up its surroundings with powerful X-rays.
Applications Accepted for 2018 Astronomy in Chile Educator Ambassadors Program

Applications are now being accepted for the 2018 Astronomy in Chile Educator Ambassadors Program (ACEAP).
This program, in its fourth year, brings amateur astronomers, planetarium personnel, and astronomy educators to several U.S.-funded astronomy observatories in Chile. While there, ambassadors will receive behind-the-scenes tours of some of the world’s most productive and advanced telescopes, including in-depth information on their instruments and discoveries.
ACEAP is a collaborative project of Associated Universities, Inc., the National Radio Astronomy Observatory, National Optical Astronomy Observatory, and Gemini Observatory. ACEAP was initially funded in 2015 as a two-year pilot program by the National Science Foundation (NSF). Due to its success, NSF decided to fund the program for an additional two years.
To be eligible for this program, individuals must be U.S. citizens or permanent residents. Ambassadors may be either amateur astronomers, kindergarten through college (formal and informal) educators who teach astronomy as part of their curriculum or program, planetarium educators, or others who communicate astronomy to the public.
The ACEAP partners will select eight ambassadors from across the United States and its territories for the excursion, which will begin on 10 June 2018 and continue through 18 June 2018. This nine-day expedition (not including travel time between the U.S. and Chile) will include stops at the Cerro Tololo Inter-American Observatory (CTIO), Gemini-South Observatory, and the Atacama Large Millimeter/submillimeter Array (ALMA).
