NASA has partnered with Google to harness Machine learning and discovered a new planet outside our solar system, The Kepler-90i.
故选A。 (4)题详解: 主旨大意题。根据第一段第一句“A new study focuses on K2-18b, an exoplanet(系外行星) discovered in 2018, (一项新的研究将注意力集中在2018年发现的系外行星,K2-18b上)”可知本文主要介绍对K2-18b行星的研究。故选D。
Conclusions.We confirm the low impact of stellar activity on exoplanet detectability for solar-type stars, although it plays a significant role for the closest stars such asαCen A and B. We identify the best targets to be the stars with a close habitable zone. However, for the few stars...
