All findings are embargoed until the time of presentation at the meeting. “Time of presentation” means the start time of the oral or poster session in which the paper will be given, or the start time of the corresponding press conference (if any), whichever comes first. See the complete AAS embargo policy for more information.

Note: All new discoveries are subject to confirmation by independent teams of scientists. Inclusion here does not imply endorsement by the American Astronomical Society. The AAS does not endorse individual scientific results.

Press Conference Livestreams

Journalists (and anyone else) unable to attend the meeting in person may tune in to our livestreamed briefings via one of two methods:

  1. Meeting registrants may access the livestreams via Zoom links that will be provided within the vFairs platform for each press conference event. Viewers who join the livestreams via these links will be able to ask questions via a Q&A chat box.
  2. Non-registrants may access the livestreams via the AAS Press Office YouTube channel. Viewers here will not be able to ask questions.

After the meeting, archived webcasts will be freely available via our online archive, which links to the individual briefing videos on the AAS Press Office YouTube channel.

Press Tour to University of Washington Astronomy Labs

Press registrants will have the opportunity to join for a special tour after AAS 241 of several astronomy labs at the University of Washington (UW), spanning from data science to satellite instrumentation.

The Space & Ground Instrumentation group, led by Sarah Tuttle, focuses on ultraviolet and fiber-based instrumentation. The Virtual Planetary Laboratory, led by Vikki Meadows, is leading the way in simulating exoplanet atmospheres and beyond — especially applicable with recent results from JWST. We’ll also touch base with several groups focused on the Vera Rubin Observatory and the Legacy Survey of Space and Time (LSST), as well as UW’s eScience institute.

The tour will be held on Friday, 13 January at 10:30 am PT. We estimate it will last approximately 2 hours, followed by an opportunity to meet and talk in more detail with UW astronomers at their weekly pizza lunch at 12:30 pm. To sign up and to ensure you receive future news about this tour, please fill out the online expression of interest form.

Thanks to Sarah Tuttle and colleagues for arranging this tour.
