COMMITTEE ON ASTRONOMY AND ASTROPHYSICS

在发现的推动下，在技术和想象力的飞跃下，我们对宇宙的理解在过去几十年中发生了巨大的变化。天文学和天体物理学领域继续与物理学、化学、生物学和计算机科学建立新的联系。实现这些科学机会取决于保持和加强研究事业的基础。基于天文学和天体物理学的十年调查，新世界，天文学和天体物理学的新视野，天文学和天体物理学委员会（CAA）确定了天文学和天体物理学界关注的问题，并为联邦机构提供了关于他们的天文学和天体物理学研究计划的指导，以鼓励该领域的发展。的科学进步。CAA由物理学和天文学委员会以及国家科学院工程和物理科学司空间研究委员会主持。天文学和天体物理学委员会的活动有助于将支助机构的信息传播到更广泛的社区，并向机构官员提供社区投入。CAA定期收集来自天文学、天体物理学和物理学社区的信息。此外，委员会成员还与机构官员、国会工作人员以及天文学和天体物理学界的成员匡威。 工作人员和委员会成员还参加美国天文学会的年会，偶尔也参加美国科学促进协会和美国物理学会的年会。 CAA得到了NASA和NSF的支持。

Driven by discoveries, and enabled by leaps in technology and imagination, our understanding of the Universe has changed dramatically over the course of the last few decades. The fields of astronomy and astrophysics continue to create new connections to physics, chemistry, biology, and computer science. Realizing these scientific opportunities is contingent upon maintaining and strengthening the foundations of the research enterprise. Based on the decadal survey of astronomy and astrophysics, New Worlds, New Horizons in Astronomy and Astrophysics, the Committee on Astronomy and Astrophysics (CAA) identifies issues of concern to the astronomy and astrophysics community and provides guidance to federal agencies regarding their astronomy and astrophysics research programs in order to encourage the field?s scientific progress. The CAA is under the auspices of the Board on Physics and Astronomy and the Space Studies Board of the Division on Engineering and Physical Sciences at the National Academy of Sciences. The activities of the Committee on Astronomy and Astrophysics serve to disseminate information from the supporting agencies into the broader community, as well as provide the agency officials with community-based input. The CAA routinely gathers input from the astronomy, astrophysics, and physics communities. Additionally, members of the committee converse with agency officials, congressional staff, and members of the astronomy and astrophysics community. Staff and committee members also participate in annual meetings of the American Astronomical Society and, occasionally, the American Association for the Advancement of Science and American Physical Society. The CAA is supported by NASA and NSF.
