Five new scientific results from the Atacama Large Millimeter/submillimeter Array (ALMA), the Very Large Array (VLA), and the Green Bank Observatory (GBO) will be revealed at multiple press conferences during the 241st meeting of the American Astronomical Society (AAS) from January 8 to 12, 2023, in Seattle, Wash.

The AAS meeting includes a series of press conferences based on a range of themes. Presentations will highlight new research, including a peek at how turbulence and very hungry black holes are shaping their environments, what masers and magnetic fields are revealing about the lives of massive stars, and how scientists right here on Earth are exploring the Solar System using high-powered radar techniques.

Press conferences will be held in person during the conference, and streamed live on the AAS Press Office YouTube Channel.

Note: Each press conference consists of a panel of scientists presenting 4-5 unique scientific results. The number listed in parentheses indicates the order of presentation for the listed result. 

All press conferences are listed and will occur in Pacific Time.

About NRAO

The National Radio Astronomy Observatory (NRAO) is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.

About Green Bank Observatory

The Green Bank Observatory is a facility of the National Science Foundation and is operated by Associated Universities, Inc. The first national radio astronomy observatory in the U.S., it is home to the 100-meter Green Bank Telescope, the largest fully-steerable radio telescope in the word.

About ALMA

The Atacama Large Millimeter/submillimeter Array (ALMA), an international astronomy facility, is a partnership of the European Organisation for Astronomical Research in the Southern Hemisphere (ESO), the U.S. National Science Foundation (NSF) and the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Republic of Chile. ALMA is funded by ESO on behalf of its Member States, by NSF in cooperation with the National Research Council of Canada (NRC) and the Ministry of Science and Technology (MOST) and by NINS in cooperation with the Academia Sinica (AS) in Taiwan and the Korea Astronomy and Space Science Institute (KASI).

ALMA construction and operations are led by ESO on behalf of its Member States; by the National Radio Astronomy Observatory (NRAO), managed by Associated Universities, Inc. (AUI), on behalf of North America; and by the National Astronomical Observatory of Japan (NAOJ) on behalf of East Asia. The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA.
