On the night 175 years ago on Sept. 23-24, 1846, astronomers discovered Neptune, the eighth planet orbiting our Sun. The discovery was made based on mathematical calculations of its predicted position due to observed perturbations in the orbit of the planet Uranus. The discovery was made using a telescope since Neptune is too faint to be visible to the naked...
The atmospheric glow blankets the Earth’s horizon beneath the stars, as shown in a photo taken while the International Space Station orbited 261 miles above the Pacific Ocean southeast of Japan. 如国际空间站在日本东南的太平洋上空261英里处运行时拍摄的照片所示，大气层的光辉覆盖了星空下的地球地平线。 On Tuesday, Sept. 28, three residents of the station will take a short ride aboard a Soyuz MS-18, relocat...
Time capsules from the birth of our Solar System more than 4 billion years ago, the swarms of Trojan asteroids associated with Jupiter are thought to be remnants of the primordial material that formed the outer planets. The Trojans orbit the Sun in two loose groups, with one group leading ahead of Jupiter in its path, the other trailing behind. Clustered aro...

Credits: ESA/Hubble and NASA, A. Nota, C. Britt This comparison of two images shows puffing dust bubbles and an erupting gas shell – the final acts of a monster star’s life. 这两张图片的对比显示了膨胀的尘埃气泡和喷发的气体外壳——这是一颗巨型恒星生命的最后一幕。 These new views showcase the dual nature of the star AG Carinae, which was the target of the NASA/ESA Hubble Space Telescope’s 31st anniversa...
NASA’s Revolutionary Vertical Lift Technology Project’s Mobile Acoustics Facility is parked in the background of Joby’s prototype aircraft near Big Sur, California. As the aircraft flew planned test scenarios, NASA’s Advanced Air Mobility National Campaign team collected information about how the vehicle moved, how the vehicle sounded, and how the vehi...
