NASA 的星际边界探测器 (IBEX) 于 2008 年 10 月启动，提供了第一张能量分辨的全天空图，其中显示了来自日光层边界与当地星际介质 (LISM) 的高能中性原子 (ENA) 发射。这些地图揭示了一条神秘的“丝带”，即排放量增加，叠加在 ENA 排放量的平稳变化的全球分布上。色带位于两艘航海者穿过终端激波的位置之间，并且它们在穿过日光层的轨迹上没有被采样。 IBEX 对色带的发现——理论和数值模拟完全无法预测的一个特征——需要一个新的范式来理解日光层/LISM 相互作用。这条带似乎是根据星际磁场和太阳风的纬度结构排列的。丝带的起源，无论是来自日光层还是 LISM 之外发生的过程，都是未知的，并且是深入研究的主题。 IBEX 任务前三年的持续观测已经确定了色带的特征，包括其位置、能谱、精细结构和时间变化。在这里，我们回顾和比较了为解释色带而提出的各种假设，评估了它们解释三年来仔细分析 IBEX 天空图所出现的特征的能力，并讨论了如何利用 IBEX 扩展任务和国家研究委员会推荐的后续任务（星际测绘和加速探测器）期间不断发展的理论和观察结果来最终确定色带的真正来源。
Launched in October 2008, NASA's Interstellar Boundary Explorer (IBEX) has provided the first‐ever energy‐resolved all‐sky maps of energetic neutral atom (ENA) emissions from the boundary of the heliosphere with the local interstellar medium (LISM). The maps reveal an enigmatic “Ribbon” of enhanced emissions superposed on a smoothly varying global distribution of ENA emissions. The Ribbon lies between the locations where the two Voyagers crossed the termination shock and was not sampled by them on their trajectories out through the heliosphere. IBEX's discovery of the Ribbon—a feature completely unpredicted by theory and numerical simulations—requires a new paradigm in our understanding of the heliosphere/LISM interaction. The Ribbon appears to be ordered by the interstellar magnetic field and the solar wind's latitudinal structure. The Ribbon's origin, whether from processes occurring in the heliosphere or beyond in the LISM, is unknown and the subject of intense investigation. Continued observations over the first 3 years of the IBEX mission have characterized the Ribbon, including its location, energy spectra, fine structure, and time variations. Here we review and compare the various hypotheses that have been proposed to explain the Ribbon, assess their ability to account for the features that have emerged from 3 years of careful analysis of the IBEX sky maps, and discuss how evolving theories and observations during IBEX's extended mission and by the National Research Council's recommended follow‐on mission (the Interstellar Mapping and Acceleration Probe) will be used to finally determine the true source of the Ribbon.
