蓝色的告别

ByNASA中文

A blue halo glows around Pluto’s receding crescent in this parting image taken by NASA’s New Horizons spacecraft on July 14, 2015. At the time of this shot, New Horizons was 120,000 miles (200,000 kilometers) away from Pluto. Shown in approximate true color, the picture was constructed from a mosaic of six black-and-white images from the Long Range Reconnaissance Imager, with color added from a lower resolution Ralph/Multispectral Visible Imaging Camera color image. Scientists believe the haze is a smog resulting from the action of sunlight on methane and other molecules in Pluto’s atmosphere. This reaction produces a complex mixture of hydrocarbons that accumulate into small haze particles which scatter blue light. As they settle down through the atmosphere, the haze particles form numerous intricate…

Jamesa Stokes’ path to being an engineer at NASA started out on a completely different road. While she loved and excelled at math and science, she was also passionate about studio art, her first major in college. But knowing that science can also be a creative pursuit, she switched to physics and embarked on a journey to NASA when she reached grad school. Stokes, who received her bachelor’s degree in Physics from Auburn University and a Ph.D. in Materials Science and Engineering from the Pennsylvania State University, was awarded a graduate fellowship to conduct research at NASA Glenn. She later became a NASA intern and converted to a full-time Materials Research Engineer when she finished her Ph.D. “Working at NASA means tackling the bigger problems…

Two Joint Extravehicular Activity Test Team Field Test #3 (JETT3) mission members work on sample collection on the remote, rocky, high-desert terrain of the S P Crater near Flagstaff, Arizona, on Oct. 5, 2022. JETT3 was the third simulated moonwalk in preparation for future Artemis missions; during Artemis III, astronauts will visit the lunar South Pole region, which has never been explored by humans. The S P Crater has unique terrain and geology, as well as minimal communications infrastructure that make it a great location for an analog mission.

国际空间站访问南帕德雷岛

国际空间站访问南帕德雷岛

ByNASA中文

While the International Space Station orbited over the Gulf of Mexico on Sept. 19, 2022, NASA astronaut Bob Hines captured this image of South Padre Island, a barrier island along the coast of Texas. The island is part of the greater Padre Island, the longest barrier island in the world, which spans a length of 113 miles (182 kilometers). Barrier islands along the Gulf and East coasts of North America play a critical role protecting the mainland from the damaging effects of storms. They bear the brunt of large storm surges and reduce flooding on the mainland. Image Credit: NASA/Bob Hines 当国际空间站于2022年9月19日在墨西哥湾上空飞行时，NASA宇航员鲍勃·海恩斯拍摄了这张南帕德雷岛的照片，这是德克萨斯州海岸的一个屏障岛。该岛是世界上最长的堰洲岛——帕德雷岛的一部分，全长113英里(182公里)。 沿墨西哥湾和北美东海岸的堰洲岛在保护大陆免受风暴的破坏性影响方面发挥着关键作用。它们承受着大型风暴潮的冲击，减少了大陆的洪水。 影像来源：NASA/Bob Hines

Japan Aerospace Exploration Agency astronaut Koichi Wakata is pictured in his Extravehicular Mobility Unit, or spacesuit, during his spacewalk on Feb. 2, 2023. He and NASA astronaut Nicole Mann, who took this photo, installed a modification kit on the International Space Station’s starboard truss structure that will enable the future installation of the orbiting lab’s next roll-out solar array. Four solar arrays, or iROSAs, have been installed so far, and two additional arrays will be mounted to the installed platforms during future spacewalks.

哈勃对狼蛛星云的新观察

ByNASA中文

A snapshot of the Tarantula Nebula (also known as 30 Doradus) is featured in this image from the NASA/ESA Hubble Space Telescope. The Tarantula Nebula is a large star-forming region of ionized hydrogen gas that lies 161,000 light-years from Earth in the Large Magellanic Cloud, and its turbulent clouds of gas and dust appear to swirl between the region’s bright, newly formed stars. The Tarantula Nebula is a familiar site for Hubble. It is the brightest star-forming region in our galactic neighborhood and home to the hottest, most massive stars known. This makes it a perfect natural laboratory in which to test out theories of star formation and evolution, and Hubble has a rich variety of images of this region. The NASA/ESA/CSA James Webb Space…
