2022年11月19日 Artemis 1 Moonshot Image Credit & Copyright: John Kraus Explanation: When the Artemis 1 mission’s Orion spacecraft makes its November 21 powered flyby of the Moon, denizens of planet Earth will see the Moon in a waning crescent phase. The spacecraft will approach to within about 130 kilometers of the lunar surface on its way to a dista...
A small, dense cloud of gas and dust called CB 130-3 blots out the center of this image from the NASA/ESA Hubble Space Telescope. CB 130-3 is an object known as a dense core, a compact agglomeration of gas and dust. This particular dense core is in the constellation Serpens and seems to billow across a field of background stars. Dense cores like CB 130-3 are...

Koekemoer (STScI), Alyssa Pagan (STScI) Explanation: The protostar within dark cloud L1527 is a mere 100,000 years old, still embedded in the cloud of gas and dust that feeds its growth. In this NIRCam imag...

NASA的詹姆斯·韦伯太空望远镜揭示了L1527暗云中原恒星曾经隐藏的特征，为了解一颗新恒星的起源提供了线索。金牛座恒星形成区域内的这些炽热的云只在红外光中可见，这使得它成为韦伯近红外相机（NIRCam）的理想目标。 原恒星本身隐藏在这个沙漏形状的“颈部”中。一个边缘的原行星盘看起来是一条穿过颈部中间的黑线。来自原恒星的光在这个圆盘的上方和下方泄漏出来，照亮了周围气体和尘埃中的空洞。 NASA詹姆斯·韦伯太空望远镜近红外相机（NIRCam）拍摄的这张图片显示了L1527暗星云中的原恒星，它被嵌入在为其生长提供动力的物质云中。这颗恒星的喷射物清除了它上下的空洞，在这幅红外图像中，这些空洞的边界发出橙色和蓝色的光。由于恒星的“打嗝”或零星的喷射，中上区域呈现出类似气泡的形状。 影像来源：NASA, ESA, CSA...
2022年11月17日 Planet Earth from Orion Image Credit: NASA, Artemis 1 Explanation: A Space Launch System rocket left planet Earth on Wednesday, November 16 at 1:47am EST carrying the Orion spacecraft on the Artemis 1 mission, the first integrated test of NASA’s deep space exploration systems. Over an hour after liftoff from Kennedy Space Center’s historic ...
Our Space Launch System (SLS), the most powerful rocket in the world, carrying the Orion spacecraft launches on the Artemis I flight test, Wednesday, Nov. 16, 2022, from Launch Complex 39B at NASA’s Kennedy Space Center in Florida at 1:47 a.m. EST. Artemis I is the first integrated flight test of the agency’s deep space exploration systems: the Orion spacecr...
2022年11月16日星期三，NASA的太空发射系统火箭携带猎户座飞船在阿尔忒弥斯1号飞行测试中发射，发射地点位于佛罗里达州的NASA肯尼迪航天中心的39B发射场。NASA的阿尔忒弥斯1号任务是该机构深空探索系统的首次综合飞行测试：包含猎户座飞船、太空发射系统（SLS）火箭和地面系统。SLS和猎户座飞船于美国东部时间凌晨1:47从肯尼迪航天中心的39B发射台发射。 影像来源：NASA/Bill Ingalls 继世界上最强大的火箭——NASA的太空发射系统(SLS)成功发射后，该机构的猎户座飞船作为阿尔忒弥斯计划的一部分，正在前往月球的途中。SLS搭载一枚无人猎户座火箭，于美国东部时间周三凌晨1点47分从NASA位于佛罗里达州肯尼迪航天中心的39B发射台升空，进行了首次飞行测试。 这次发射是任务的第一站，猎户座...
2022年11月16日 In the Arms of NGC 1097 Image Credit & Copyright: Mike Selby, Mark Hanson Explanation: Spiral galaxy NGC 1097 shines in southern skies, about 45 million light-years away in the heated constellation Fornax. Its blue spiral arms are mottled with pinkish star forming regions in this colorful galaxy portrait. They seem to have wrapped around a s...
The Moon is seen rising above NASA’s Space Launch System (SLS) rocket with the Orion spacecraft at Launch Pad 39B as preparations for launch continue, Monday, Nov. 14, 2022, at NASA’s Kennedy Space Center in Florida. Launch of the uncrewed flight test is targeted for no earlier than Nov. 16 at 1:04 a.m. EST. Coverage begins with cryogenic fueling of the SLS ...
