2024年1月25日 Jyväskylä in the Sky Image Credit & Copyright: Harri Kiiskinen Explanation: You might not immediately recognize this street map of a neighborhood in Jyväskylä, Finland, planet Earth. But that’s probably because the map was projected into the night sky and captured with an allsky camera on January 16. The temperature recorded on that northern winter night was around minus 20 degrees Celsius. As ice crystals formed in the atmosphere overhead, street lights spilling illumination into the sky above produced visible light pillars, their ethereal appearance due to specular reflections from the fluttering crystals’ flat surfaces. Of course, the projected light pillars trace a map of the brightly lit local streets, though reversed right to left in the upward looking camera’s view. This light pillar…

NASA’s twin rovers, Spirit and Opportunity, stand on the Martian landscape in this poster created to commemorate their 20th landing anniversary. The rovers landed in January 2004, on opposite sides of the planet in locales that scientists suspected had been affected by liquid water in the past. Their main scientific objective was to search for a range of rocks and soil types and then look for clues for past water activity on Mars—and what they found rewrote textbooks. In addition to proving that water once existed on Mars, the rovers also far exceeded their initial planned lifetimes. Spirit operated for 6 years, 2 months, and 19 days, more than 25 times its original intended lifetime, and Opportunity operated for almost 15 years, setting several records….

2024年1月24日 Earth and Moon from Beyond Image Credit: NASA, Artemis I; Processing: Andy Saunders Explanation: What do the Earth and Moon look like from beyond the Moon? Although frequently photographed together, the familiar duo was captured with this unusual perspective in late 2022 by the robotic Orion spacecraft of NASA‘s Artemis I mission as it looped around Earth’s most massive satellite and looked back toward its home world. Since our Earth is about four times the diameter of the Moon, the satellite’s seemingly large size was caused by the capsule being closer to the smaller body. Artemis II, the next launch in NASA’s Artemis series, is currently scheduled to take people around the Moon in 2025, while Artemis III is planned to return humans to…

A SpaceX Falcon 9 rocket carrying the company’s Dragon spacecraft lifts off from NASA’s Kennedy Space Center in Florida on Thursday, Jan. 18, 2024. Axiom Space’s Axiom Mission 3 (Ax-3) is the third all-private astronaut mission to the space station, sending crew members Commander Michael López-Alegría, Pilot Walter Villadei of Italy, Mission Specialist Alper Gezeravcı of Turkey, and ESA (European Space Agency) project astronaut Marcus Wandt of Sweden into orbit. The Ax-3 crew will spend about two weeks conducting microgravity research, educational outreach, and commercial activities aboard the space station. Watch our Axiom Mission 3 launch coverage on NASA+.

2024年1月23日 Deep Nebulas: From Seagull to California Image Credit & Copyright: Alistair Symon Explanation: How well do you know the night sky? OK, but how well can you identify famous sky objects in a very deep image? Either way, here is a test: see if you can find some well-known night-sky icons in a deep image filled with faint nebulosity. This image contains the Pleiades star cluster, Barnard’s Loop, Horsehead Nebula, Orion Nebula, Rosette Nebula, Cone Nebula, Rigel, Jellyfish Nebula, Monkey Head Nebula, Flaming Star Nebula, Tadpole Nebula, Aldebaran, Simeis 147, Seagull Nebula and the California Nebula. To find their real locations, here is an annotated image version. The reason this task might be difficult is similar to the reason it is initially hard to…

In this image from May 22, 2023, a NASA intern uses an augmented reality headset to test out heads-up display technology being developed for future Artemis missions. This technology was created as part of the NASA Spacesuit User Interface Technologies for Students, or SUITS, design challenge in which college students from across the country help design user interface solutions for future spaceflight needs. Today marks the beginning of NASA’s Spring 2024 internship season; across the country, hundreds of interns are joining the Artemis Generation and contributing to the agency’s mission of exploring the universe for the benefit of all. The deadline for Summer 2024 internship applications is Feb. 2. Learn more and apply at intern.nasa.gov. Image Credit: NASA/James Blair 在这张2023年5月22日的照片中，NASA的一名实习生使用增强现实耳机测试为未来的阿尔忒弥斯任务开发的平视显示技术。这项技术是NASA学生宇航服用户界面技术设计挑战赛的一部分，来自全国各地的大学生帮助设计未来太空飞行需求的用户界面解决方案。 今天标志着NASA 2024年春季实习季的开始；在全国各地，数百名实习生正在加入阿耳忒弥斯一代，并为该机构探索宇宙造福全人类的使命做出贡献。 2024年夏季实习申请截止日期为2月2日。了解更多信息并在intern.nasa.gov上申请。 图片来源: NASA/James…

2024年1月22日 Shadows of Mountain and Moon Image Credit & Copyright: Enzo Massa Micon Explanation: Can the Moon and a mountain really cast similar shadows? Yes, but the division between light and dark does not have to be aligned. Pictured, a quarter moon was captured above the mountain Grivola in Italy in early October of 2022. The Sun is to the right of the featured picturesque landscape, illuminating the right side of the Moon in a similar way that it illuminates the right side of the mountain. This lunar phase is called “quarter” because the lit fraction visible from Earth is one quarter of the entire lunar surface. Digital post-processing of this single exposure gave both gigantic objects more prominence. Capturing the terminator of this quarter…

A top-down view of the OSIRIS-REx Touch-and-Go-Sample-Acquisition-Mechanism (TAGSAM) head with the lid removed, revealing the remainder of the asteroid sample inside. Photo: NASA/Erika Blumenfeld & Joseph Aebersold The astromaterials curation team at NASA’s Johnson Space Center in Houston has completed the disassembly of the OSIRIS-REx sampler head to reveal the remainder of the asteroid Bennu sample inside. On Jan. 10, they successfully removed two stubborn fasteners that had prevented the final steps of opening the Touch-and-Go-Sample-Acquisition-Mechanism (TAGSAM) head. Erika Blumenfeld, creative lead for the Advanced Imaging and Visualization of Astromaterials (AIVA) and Joe Aebersold, AIVA project lead, captured this photograph of the open TAGSAM head including the asteroid material inside using manual high-resolution precision photography and a semi-automated focus stacking procedure. The result is an…

2024年1月21日 The Upper Michigan Blizzard of 1938 Image Credit: Bill Brinkman; Courtesy: Paula Rocco Explanation: Yes, but can your blizzard do this? In the Upper Peninsula of Michigan‘s Storm of the Century in 1938, some snow drifts reached the level of utility poles. Nearly a meter of new and unexpected snow fell over two days in a storm that started 86 years ago this week. As snow fell and gale-force winds piled snow to surreal heights, many roads became not only impassable but unplowable; people became stranded, cars, school buses and a train became mired, and even a dangerous fire raged. Two people were killed and some students were forced to spend several consecutive days at school. The featured image was taken by a local…
