AI 中文摘要
我们回顾了宇宙微波背景辐射的观测现状。本章是对十年前发表在《广义相对论百年：从起源、实验基础到引力波、宇宙学和量子引力》一书中的《宇宙微波背景辐射各向异性物理学》的更新。早期贡献总结了当时该领域的状态以及基础宇宙学和引力物理学。本文报告了2015 - 2025年间该领域的新进展，并回顾了未来前景。
英文摘要
We review the present status of observations of the Cosmic Microwave Background. This book chapter is an update to an earlier review "Physics of the Cosmic Microwave Background Anisotropy" that appeared a decade ago in the compilation "One Hundred Years of General Relativity: From Genesis and Empirical Foundations to Gravitational Waves, Cosmology and Quantum Gravity." The earlier contribution summarized the state of the field then as well as the underlying cosmology and gravitational physics. This contribution reports on what new has occurred in the field during the intervening time 2015-2025. We also review future prospects.
