Nancy Grace Roman (1925-2018), NASA’s first chief astronomer, is known as the ‘Mother of Hubble.’ In a time when women were discouraged from studying math and science, Roman became a research astronomer and was instrumental in taking NASA’s Hubble Space Telescope from an idea to reality and establishing NASA’s program of space-based astronomical observatories. In this image from the early 1970s, Dr. Roman is shown at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

NASA’s Juno mission captured this look at Jupiter’s tumultuous northern regions during the spacecraft’s close approach to the planet on Feb. 17, 2020. Notable features in this view are the long, thin bands that run through the center of the image from top to bottom. Juno has observed these long streaks since its first close pass by Jupiter in 2016. The streaks are layers of haze particles that float above the underlying cloud features. Scientists don’t yet know exactly what these hazes are made of or how they form. Two jet streams in Jupiter’s atmosphere flank either side of the region where the narrow bands of haze typically appear, and some researchers speculate those jet streams may influence the formation of the high hazes. This…
2020 May 16 The Dark River to Antares Composite Image Credit & Copyright: Paul Schmit Explanation: A dark river seems to flow through this sky from the horizon toward colorful clouds near red giant star Antares. Murky looking, the dark river is a dusty nebula obscuring background starlight near the central Milky Way, although the dark dust nebula contains mostly hydrogen molecular gas. Dust scattering starlight around Antares, alpha star of Scorpius, creates the unusual yellow-hued reflection nebula. Above it, bright blue double star Rho Ophiuchi is embedded in more typical dusty bluish reflection nebulae, with red emission nebulae also scattered through the interstellar space. Globular star cluster M4 looks almost like a bright star just above and right of Antares, though it lies far…
Northrup Grumman’s Cygnus resupply ship, with its prominent cymbal-shaped UltraFlex solar arrays, is pictured in the grips of the Canadarm2 robotic arm moments before its release ending its 83-day stay at the International Space Station on May 11, 2020. Within 24 hours of its release, Cygnus began its secondary mission, hosting the Spacecraft Fire Safety Experiment – IV (Saffire-IV), which provides an environment to safely study fire in microgravity. It also deployed a series of payloads. Northrop Grumman flight controllers in Dulles, Virginia, will initiate Cygnus’ deorbit to burn up in Earth’s atmosphere Friday, May 29.

Iowa native astronaut Raja Chari was selected by NASA to join the 2017 Astronaut Candidate Class. He is a graduate of the U.S. Air Force Academy with bachelor’s degrees in astronautical engineering and engineering science, and later earned a master’s degree in aeronautics and astronautics from Massachusetts Institute of Technology. In addition, he graduated from the U.S. Naval Test Pilot School. At the time of his selection in June 2017, Chari was a colonel in the U.S. Air Force, serving as the Commander of the 461st Flight Test Squadron and the Director of the F-35 Integrated Test Force. He has accumulated more than 2,000 hours of flight time in the F-35, F-15, F-16, and F-18. #AAPI Image Credit: NASA/Bill Ingalls 爱荷华州本土宇航员拉贾·查里(Raja Chari)被美国国家航空航天局(NASA)选为2017年宇航员候选人。他毕业于美国空军学院(U.S. Air Force Academy)，获得航天工程和工程科学学士学位，后来在麻省理工学院(Massachusetts…
Several hundred million years ago, two galaxy clusters collided and then passed through each other. This mighty event released a flood of hot gas from each galaxy cluster that formed an unusual bridge between the two objects. This bridge is now being pummeled by particles driven away from a supermassive black hole. Galaxy clusters are the largest objects in the universe held together by gravity. They contain hundreds or thousands of galaxies, vast amounts of multi-million-degree gas that glow in X-rays, and enormous reservoirs of unseen dark matter. The system known as Abell 2384 shows the giant structures that can result when two galaxy clusters collide. A superheated gas bridge in Abell 2384 is shown in this composite image of X-rays from NASA’s Chandra X-ray…
NASA astronaut Ricky Arnold takes an out of this world “space-selfie” while conducting a spacewalk on March 29, 2018. Before he joined the Astronaut Corps, Arnold was a teacher, who taught all over the world from Malaysia to Romania. As an astronaut he served on STS-119 and aboard the International Space Station’s Expedition 55/56. #TeacherAppreciationWeek Image Credit: NASA 2018年3月29日，美国宇航局宇航员瑞奇·阿诺德在太空行走时进行了“太空自拍”。 在他成为宇航员之前，阿诺德是一位老师，从马来西亚到罗马尼亚，他在世界各地任教。作为一名宇航员，他曾在STS-119和国际空间站的第55/56号远征队上服务。 #TeacherAppreciationWeek 图片来源:NASA
Blooming roses at the Armstrong Flight Research Center (AFRC) highlight the Bell X-IE aircraft mounted in front of the main building at the center. The X-1E was one of the first supersonic aircraft and was the last of the X-1 series of aircraft. It was last flown in November 1958 and now resides at the center. The aircraft was developed by NASA’s predecessor, the National Advisory Committee on Aeronautics. AFRC, formerly known as the Dryden Flight Research Center, has a long history of aeronautical research. AFRC has developed and operates some of the most advanced aircraft in the world and is known for many aviation firsts, including critical support for the first crewed airplane to exceed the speed of sound and the first digital fly-by-wire…
In this image from 1969, Life Detection Systems branch chief Vance Oyama operates a specially designed soil distribution system, used for dispersing the lunar soil in equal amounts to thousands of petri dishes as part of the lunar biological experiments performed at NASA’s Ames Research Center. Oyama had a long career at NASA and also helped to design experiments for the Viking Mars Landers. This is one of a series of photos from 1969 that shows researchers at NASA’s Ames Research Center examining samples of Moon rocks and soil and that astronauts brought back from the Apollo 11 mission. The researchers are looking for signs of life endemic to the Moon, as well as organic compounds that are the basic building blocks of life. Of…
