Discovered in 2016, a roughly Earth-sized planet orbiting our nearest neighboring star might be habitable, according to astronomers using the European Southern Observatory’s 3.6-meter telescope at La Silla, Chile, along with other telescopes around the world. The exoplanet is at a distance fro
In this image, one of the radiation detectors for the Radi-N2 experiment floats in the space station. This device will help researchers explore the radition risk to humans in space. Neutrons make up a significant part of the radiation exposure in low-Earth orbit, but have not been well characterized

迈进美国下一次宇航员发射目标；又一次成功的空间站补给任务；美国国家航空日（National Aviation Day）对飞行员进行表彰认可……最近新闻速递，尽在「本周NASA」！ NASA的SpaceX第一次载人飞行任务（Crew-1）飞往国际空间站的计划发射时间在10月23日或之后。SpaceX载人运输系统的NASA认证将允许SpaceX定期发射前往空间站的载人飞行任务，这结束了NASA对俄罗斯的唯一依赖。 8月18日，日本宇宙航空研究开发机构（Japan Aerospace Exploration Agency）的HTV-9货运飞船在3个月的停留后离开了国际空间站。HTV-9提供了大约4吨
This image from the NASA/ESA Hubble Space Telescope features the spectacular galaxy NGC 2442, nicknamed the Meathook galaxy owing to its extremely asymmetrical and irregular shape. This galaxy was host to a supernova explosion spotted in March 2015, known as SN 2015F, that was created by a white dwa
