Over 2200 astronomers and physics teachers attended the AAS/AAPT Joint 2007 Winter Meeting. Most of the 2007 AAS/AAPT plenary presentations and press events are available here. Catch up on what the astronomical research community’s been up to and hear about their efforts to probe the frontiers of the cosmos.
AAS/AAPT does not endorse individual reports of new discoveries, whether featured in our press conferences or described in press releases. All new findings require independent verification.
