The outermost layer of the Sun’s atmosphere—the corona—releases plasma, a continuous stream of charged particles that constitutes the solar wind. This stream travels past the planets into interstellar space and fills up a region called the heliosphere. Capturing the energetics of the solar wind can provide information regarding the origin, evolution, and habitability of stellar systems (1). Spacecraft, including the Parker Solar Probe and the Solar Orbiter, were launched to study the inner part of the heliosphere that is close to the Sun. On page 962 of this issue, Rivera et al. (2) report on the energetics of the solar wind based on measurements from the two spacecraft while they were radially aligned near the Sun and observing the same solar wind stream. The results support the importance of Alfvén waves—a common type of plasma wave originating in the solar corona—and suggest other potential factors that drive heating and acceleration of the solar wind.
期刊介绍:
Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research.
Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated.
Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
