进步73号货运飞船离开空间站

To make room for the latest cargo craft, on Nov. 29 the Progress 73 departed the station after undocking from the Pirs docking compartment, as shown in this image. Loaded with trash, the craft was deorbited a few hours later and burned up safely over the Pacific Ocean. Traveling approximately 260 miles over the Yellow Sea east of Shanghai, the automated Russian Progress 74 cargo resupply spacecraft docked at 5:35 a.m. EST on Dec. 9 to the Pirs docking compartment on the Russian segment of the International Space Station. It was the second resupply spacecraft to arrive for the six crew members aboard the space station in as many days.

船底座星云的“神秘山”

船底座星云的“神秘山”

Within the tempestuous Carina Nebula lies “Mystic Mountain.” This three-light-year-tall cosmic pinnacle, imaged by the Hubble Space Telescope’s Wide Field Camera 3 in 2010, is made up primarily of dust and gas, and exhibits signs of intense star-forming activity. The colors in this composite image correspond to the glow of oxygen (blue), hydrogen and nitrogen (green) and sulfur (red). Image Credit: NASA, ESA, M. Livio and the Hubble 20th Anniversary Team (STScI) 在汹涌的船底座星云中坐落着一座“神秘山”。2010年，哈勃太空望远镜的广角相机3号拍摄到了这个三光年高的宇宙尖塔，它主要由尘埃和气体组成，并显示出强烈的恒星形成活动的迹象。这张合成图中的颜色分别代表了氧(蓝色)、氢和氮(绿色)和硫(红色)的辉光。 图片来源:NASA, ESA, M.

“机器人旅馆”发射到国际空间站

Robots need a place to stay in space, too. NASA is attaching a “robot hotel” to the outside of the International Space Station with the upcoming launch of the Robotic Tool Stowage (RiTS), a protective storage unit for critical robotic tools. On Dec. 4, RiTS is slated to launch aboard the 19th SpaceX commercial resupply mission. Its first residents will be two Robotic External Leak Locators (RELL). Outfitted with mass spectrometers capable of sniffing out the presence of gases such as ammonia, these robotic tools are used to detect leaks from the station. Two RELL units are on board the station right now: the first RELL launched in 2015, and it proved to be such a success that a second RELL was launched as a…

Just after its close flyby of Jupiter on Nov. 3, 2019, NASA’s Juno spacecraft caught this striking view of Jupiter’s southern hemisphere as the spacecraft sped away from the giant planet. This image captures massive cyclones near Jupiter’s south pole, as well as the chaotic clouds of the folded filamentary region — the turbulent area between the orange band and the brownish polar region. When this image was taken, Juno was traveling at about 85,000 mph (137,000 kilometers per hour) relative to the planet. A little more than an hour earlier — at the point of closest approach to the cloud tops — the spacecraft reached speeds relative to Jupiter in excess of 130,000 mph (209,000 kilometers per hour). Citizen scientist Ali Abbasi created this…

黑洞孕育着百万光年之外的新星

黑洞孕育着百万光年之外的新星

ByNASA中文

Black holes are famous for ripping objects apart, including stars. But now, astronomers have uncovered a black hole that may have sparked the births of stars over a mind-boggling distance, and across multiple galaxies. If confirmed, this discovery, made with NASA’s Chandra X-ray Observatory and other telescopes, would represent the widest reach ever seen for a black hole acting as a stellar kick-starter. The black hole seems to have enhanced star formation more than one million light-years away. (One light year is equal to 6 trillion miles.) “This is the first time we’ve seen a single black hole boost star birth in more than one galaxy at a time,” said Roberto Gilli of the National Institute of Astrophysics (INAF) in Bologna, Italy, lead author of…

NASA astronaut Andrew Morgan is seen here tethered to the Starboard-3 truss segment work site during the second spacewalk to repair the International Space Station’s cosmic particle detector, the Alpha Magnetic Spectrometer. During the 6.5 hour spacewalk, Morgan and Station Commander Luca Parmitano of the European Space Agency the two successfully cut eight stainless steel tubes, including one that vented the remaining carbon dioxide from the old cooling pump. The crew members also prepared a power cable and installed a mechanical attachment device in advance of installing the new cooling system. This work clears the way for Parmitano and Morgan’s next spacewalk in the repair series Monday Dec. 2. The plan is to bypass the old thermal control system by attaching a new one off…

For this image, the NASA/ESA Hubble Space Telescope turned its powerful eye toward an emission-line galaxy called NGC 3749. When astronomers explore the contents and constituent parts of a galaxy somewhere in the universe, they use various techniques and tools. One of these is to spread out the incoming light from that galaxy into a spectrum and explore its properties. This is done in much the same way as a glass prism spreads white light into its constituent wavelengths to create a rainbow. By hunting for specific signs of emission from various elements within a galaxy’s spectrum of light —so-called emission lines — or, conversely, the signs of absorption from other elements — so-called absorption lines — astronomers can start to deduce what might be…

Days before his 13th birthday, Edward Gonzales lost his father. In spite of childhood hardships, the strong work ethic that his father instilled drove him to obtain employment at one of the largest law firms on the West Coast – O’Melveny and Myers LLP. While at O’Melveny, he managed the Mail Services Department and supported events for former Secretary of State, the Honorable Warren Christopher. After working for the firm for over a decade and furthering his education, a friend mentioned an opening at NASA’s Jet Propulsion Laboratory (JPL). He was hired as a business administrator, but quickly gravitated to the education side of the house. Since 2001, he has worked with underserved, underrepresented minorities and communities in the capacity of mentoring, co-managing various programs,…
