蝎虎座的恒星比星系更耀眼

ByNASA中文 2022年9月1日2022年9月1日

A little-studied star, TYC 3203-450-1, upstages a galaxy in this Hubble Telescope image from December 2017. Both the star and the galaxy are within the Lizard constellation, Lacerta. However, the star is much closer than the much more distant galaxy. Astronomers studying distant objects call these stars “foreground stars” and they are often not very happy about them, as their bright light is contaminating the faint light from the more distant and interesting objects they actually want to study.

窥视木星的内部生命

ByNASA中文 2022年8月31日2022年8月31日

Auroras and hazes glow in this composite image of Jupiter taken by the James Webb Space Telescope’s Near-Infrared Camera (NIRCam). NIRCam has three specialized infrared filters that showcase details of the planet. Since infrared light is invisible to the human eye, the light has been mapped onto the visible spectrum: the auroras are mapped to redder colors, hazes to yellows and greens, and light reflected from a deeper main cloud to blues.

阿波罗15号在月球地平线上拍摄地球

ByNASA中文 2022年8月27日2022年8月27日

This view of the crescent Earth over the Moon’s horizon was taken during the Apollo 15 lunar landing mission. Apollo 15 launched from the Kennedy Space Center on July 26, 1971 via a Saturn V launch vehicle. Aboard was a crew of three astronauts: David R. Scott, mission commander; James B. Irwin, lunar module pilot; and Alfred M. Worden, command module pilot. Designed to explore the Moon over longer periods, greater ranges, and with more instruments for the collection of scientific data than before, Apollo 15 included the introduction of a $40 million lunar roving vehicle (LRV) that reached a top speed of 16 kph (10 mph) across the Moon’s surface. The successful Apollo 15 lunar landing mission was the first in a series of…

NASA的T-38在阿尔忒弥斯一号上空翱翔

ByNASA中文 2022年8月27日2022年8月27日

T-38 planes are a fixture of astronaut training, assisting pilots and mission specialists to think quickly in changing situations. Here, our T-38s fly in formation above the Space Launch System (SLS) rocket on Launch Pad 39B. The SLS and Orion spacecraft for the Artemis I mission will launch no earlier than Aug. 29, 2022. Astronaut Andrew Morgan posted this and two other photos on Twitter on Aug. 25, 2022, saying “This week we flew over @NASAArtemis, thanking the @nasa centers across the country that put this Moon rocket on @NASAKennedy’s pad and celebrating the upcoming test flight!” Image credit: NASA/Josh Valcarcel T-38飞机是宇航员训练的一个固定项目，协助飞行员和任务专家在不断变化的情况下快速思考。在这里，我们的T-38飞机在39B发射台上的太空发射系统（SLS）火箭上方编队飞行。用于阿尔忒弥斯一号任务的SLS和猎户座飞船将不早于2022年8月29日发射。宇航员安德鲁·摩根于2022年8月25日在推特上发布了这张照片和另外两张照片，称“本周我们飞越了@NASAArtemis，感谢全国各地的@nasa 中心将这枚月球火箭放在@NASAKennedy 的平台上，并庆祝即将进行的试飞！” 影像来源：NASA/Josh Valcarcel

银河系的延时照片

ByNASA中文 2022年8月25日2022年8月25日

This time lapse of the Milky Way Galaxy taken from the International Space Station (ISS) also captured a lightning strike on Earth so bright that it lit up the space station’s solar panels. Astronaut Kjell Lindgren posted this on Twitter and Instagram on Sept. 2, 2015, saying, “Large lightning strike on Earth lights up or solar panels.” See more photos from the ISS. Image credit: NASA/Kjell Lindgren 这张从国际空间站（ISS）拍摄的银河系的延时照片也捕捉到了地球上的一次闪电，如此明亮，照亮了空间站的太阳能电池板。宇航员谢尔·林德格伦于2015年9月2日在Twitter和Instagram上发布了这条消息，他说:“地球上的大闪电会照亮太阳能电池板。” 查看来自国际空间站的更多照片。图片来源：NASA/Kjell Lindgren

历史性的X-1E展望未来

ByNASA中文 2022年8月24日2022年8月24日

The supersonic X-1E research aircraft was the last of NASA’s experimental X-1 series of aircraft. From 1955-1958, it made 26 flights and one captive flight (attached to a carrier aircraft). Research flights took place over what is now NASA’s Armstrong Flight Research Center in Edwards, California. In this photo from November 2021, the X-1E looks toward the full Moon.

NASA的欧罗巴快船在高湾1号

ByNASA中文 2022年8月24日2022年8月24日

The core of NASA’s Europa Clipper spacecraft has taken center stage in the Spacecraft Assembly Facility at the agency’s Jet Propulsion Laboratory in Southern California. Standing 10 feet (3 meters) high and 5 feet (1.5 meters) wide, the craft’s main body will for the next two years be the focus of attention in the facility’s ultra-hygienic High Bay 1 as engineers and technicians assemble the spacecraft for its launch to Jupiter’s moon Europa in October 2024. See more images of the spacecraft coming together.

新奥尔良上空的月亮

ByNASA中文 2022年8月21日2022年8月21日

A paddlewheeler makes its way up the Mississippi River as the Moon rises over New Orleans on Sunday evening, Aug. 22, 2021. The August Sturgeon Moon, which was also a rare Blue Moon, was full at 7:02 a.m. local time Sunday but the nearly full Moon still put on a show when it rose over New Orleans later that evening. New Orleans is home to the NASA Michoud Assembly Facility, where the core stage of the Space Launch System that will return people to the Moon was built.

旅行者1号看到了大红斑

ByNASA中文 2022年8月19日2022年8月19日

Launched in 1977, the twin Voyager probes are NASA’s longest-operating mission and the only spacecraft ever to explore interstellar space. 45 years on, Voyager 1 and 2 continue to provide us with observations of the farthest reaches of space. Our Voyager 1 spacecraft zoomed toward Jupiter in January and February 1979, capturing hundreds of images of Jupiter during its approach, including this close-up of swirling clouds around Jupiter’s Great Red Spot.
