The Board of the Atacama Large Millimeter/submillimeter Array (ALMA)— an international collaboration in which the National Science Foundation’s National Radio Astronomy Observatory (NRAO) is a partner— has approved multi-million dollar upgrades for the development of a second-generation correlator and a digital transmission system (DTS). As part of the ALMA2030 Wideband Sensitivity Upgrade, these projects aim to double and eventually quadruple the correlated bandwidth of the array.
Associated Universities, Inc. (AUI) and the National Radio Astronomy Observatory (NRAO) have awarded the 2022 Karl G.

The Jansky Lectureship is an honor established by the trustees of AUI to recognize outstanding contributions to the advancement of radio astronomy.
The National Science Foundation (NSF) and SpaceX have finalized a radio spectrum coordination agreement to limit interference from the company’s Starlink satellites to radio astronomy assets operating between 10.6 and 10.7 GHz. The agreement, detailed in a statement released by NSF today, ensures that Starlink satellite network plans will meet international radio astronomy protection standards, and protect NSF-funded radio astronomy facilities.
Shockwaves resulting from the violent collision between an intruder galaxy and Stephan’s Quintet are helping astronomers to understand how turbulence influences gas in the intergalactic medium.
