在这张由Suomi NPP卫星于2018年7月拍摄的图像中，阿拉伯半岛上空盘旋着尘埃。美NASA即将进行的地球表面矿物尘埃源调查（EMIT）将帮助科学家们更好地了解空气中的尘埃在加热和冷却大气中的作用。 影像来源：NASA Earth Observatory 名为EMIT的地球表面矿物尘埃源调查将分析从干燥地区穿过大气层的尘埃，以了解其对地球的影响。 每年，强风将来自地球沙漠和其他干旱地区的10亿吨（相当于10000艘航空母舰的重量）矿物尘埃带入大气层。虽然科学家知道尘埃会影响环境和气候，但他们没有足够的数据来详细确定这些影响是什么，或者将来可能是什么——至少现在还没有。 6月9日，NASA向 […]

NASA and the National Park Service worked together to create a web-based tool that helps park managers better understand the impact of outdoor lighting and noise on animal species in national parks. The website allows park managers to choose a time period, such as the spring or winter seasons, and t
Japan’s Geiyo Archipelago, in the Seito Inland Sea, was once home to pirates. From the 9th to the 16th centuries, the pirates dominated the Inland Sea and terrorized the coasts of East Asia. Until the Shimanami Kaido (Inland Wave Sea Road) was completed in 1999, the Geiyo Islands were a remote
