韦伯的第一张深场影像

ByNASA中文 2023年7月13日2023年7月13日

President Joe Biden unveiled this image of the galaxy cluster SMACS 0723 during a White House event on July 11, 2022. One year later, the James Webb Space Telescope has changed the way we see the universe. From new views of old subjects to discoveries on the chemical composition of exoplanets, Webb has helped us gather clues about the origins of our own solar system and beyond. To celebrate the completion of a successful first year, NASA has released Webb’s image of a small star-forming region in the Rho Ophiuchi cloud complex. Learn more about SMACS 0723 and how Webb captured this image.

阿姆斯特朗飞行研究中心的野生动物

ByNASA中文 2023年7月12日

A bobcat surveys the landscape at NASA’s Armstrong Flight Research Center in Edwards, California in this March 11, 2021, image. The spotted feline makes its home on the more than 300,000 acres of Mojave Desert surrounding the NASA facility housed at Edwards Air Force Base. Named in honor of Neil A. Armstrong, a former research test pilot at the center and the first man to step on the moon, Armstrong is NASA’s primary center for high-risk, atmospheric flight research and test projects.

新视野号的红外图像

ByNASA中文 2023年7月11日

NASA’s New Horizons spacecraft captured this high-resolution enhanced color view of Charon, Pluto’s largest moon, just before closest approach on July 14, 2015. The image combines blue, red, and infrared images taken by the spacecraft’s Ralph/Multispectral Visual Imaging Camera (MVIC); the colors are processed to best highlight the variation of surface properties across Charon. New Horizons conducted a six-month-long reconnaissance flyby study of Pluto and its moons in summer 2015, helping us understand worlds at the edge of our solar system, then venturing deeper into the distant, mysterious Kuiper Belt – a relic of solar system formation. The spacecraft is now more than 5 billion miles from Earth and uses machine-learning AI software to make searches beyond the Kuiper Belt much faster and more productive….

普赛克航天器的启动前处理

ByNASA中文 2023年7月8日

NASA’s Psyche spacecraft is nearly complete as it rests in a clean room on June 26, 2023, at Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida. Engineers and technicians have begun final assembly, test, and launch operations on Psyche, with assembly of the spacecraft all but complete except for the installation of the solar arrays and the imagers. Psyche is targeted to launch in October 2023.

The last rays of an orbital sunset begin fading in Earth’s atmosphere silhouetting the cloud tops in this June 24, 2023, photograph from the International Space Station as it orbited 271 miles above the southernmost tip of South America. The space station makes 16 orbits of the Earth in 24 hours, so astronauts on the orbital outpost see 16 sunrises and sunsets. Get more quick facts about the International Space Station. Image Credit: NASA 2023年6月24日，国际空间站在南美洲最南端上空271英里的轨道上拍摄的这张照片显示，轨道日落的最后一道光线开始在地球大气层中消退，勾勒出云顶的轮廓。国际空间站在24小时内绕地球运行16圈，因此空间站上的宇航员可以看到16次日出和日落。了解更多关于国际空间站的快速事实。影像来源：NASA

NASA的X-59迈出了关键一步

ByNASA中文 2023年7月6日

NASA’s X-59 research aircraft moves from its construction site to the flight line – or the space between the hangar and the runway – at Lockheed Martin Skunk Works in Palmdale, California, on June 16, 2023. This milestone kicks off a series of ground tests to ensure the X-59 is safe and ready to fly. The X-59 is designed to fly faster than Mach 1 while reducing the resulting sonic boom to a thump for people on the ground. NASA will evaluate this technology during flight tests as part of the agency’s Quesst mission, which helps enable commercial supersonic air travel over land.

哈勃观测到星系邻居

ByNASA中文 2023年7月2日

The highly irregular galaxy ESO 174-1, which resembles a lonely, hazy cloud against a backdrop of bright stars, dominates this image from the NASA/ESA Hubble Space Telescope. ESO 174-1 lies around 11 million light-years from Earth and consists of a bright cloud of stars and a faint, meandering tendril of dark gas and dust. This image is part of a collection of Hubble observations designed to better understand our nearby galactic neighbors. The observations aim to resolve the brightest stars and basic properties of every known galaxy within 10 megaparsecs. A parsec is a unit used by astronomers to measure the vast distances to other galaxies – 10 megaparsecs translates to 32 million light-years – and makes astronomical distances easier to handle. For example, the…
