Annie and John Glenn arrive at the Mission Control Center for the Gemini IV launch on June 4, 1965. John Glenn was the first American to orbit the Earth. Glenn’s wife Annie, who passed away May 19, 2020, was an advocate for people with disabilities, having overcome her own communications disorder to become an adjunct professor at Ohio State’s Speech Pathology Department. The couple, who were high school sweethearts, were married in 1943 until John Glenn’s death in 2016. Read the press release on Mrs. Glenn’s passing: NASA Remembers Annie Glenn.

Chemist Audrey Miyamoto preparing an Apollo lunar sample to analyze for amino acids at NASA’s Ames Research Center. 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 course, no lunar life was found in these samples, and we now know that the Moon does not harbor life. Nevertheless, these tests became the first time that NASA looked for the possibility of life existing on another world using samples from that world. Learn more…

南希·格蕾丝·罗曼：哈勃太空望远镜之母

ByNASA中文

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. Image Credit: NASA 南希·格蕾丝·罗曼(1925-2018)，美国宇航局第一位首席天文学家，被称为“哈勃太空望远镜之母”。在那个女性不被鼓励学习数学和科学的年代，罗曼成为了一名研究型天文学家，并帮助美国宇航局将哈勃太空望远镜从一个想法变成现实，并建立了美国宇航局的太空天文台项目。 在这张20世纪70年代早期的照片中，罗曼博士在马里兰州格林贝尔特的NASA戈达德太空飞行中心。 影像来源：NASA

木星上的高空雾

木星上的高空雾

ByNASA中文

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…

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.

Abell 2384：弯曲两个星系群之间的桥梁

Abell 2384：弯曲两个星系群之间的桥梁

ByNASA中文

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…
