➀ NASA的Webb望远镜成功捕捉到附近星系中多颗行星的图像,展示了其分析系外行星大气化学成分的能力。
➁ NASA确认詹姆斯·韦伯太空望远镜(JWST)已捕捉到地球银河系附近多个系外行星的直接图像。
➂ 通过对HR 8799行星系统的观测,Webb望远镜收集了强有力的证据,表明该系统中的四颗气态巨行星的形成方式与木星和土星相似,它们通过缓慢构建固体核心最终从原行星盘吸收气体。

➀ Astronauts on the ISS witnessed the explosion of SpaceX's Starship upper stage due to an 'energetic event';
➁ The spacecraft lost altitude and communication after the explosion;
➂ Starship initiated its RUD protocol, leading to its disassembly in the upper atmosphere.
➀ NASA has updated the impact probability of asteroid 2024 YR4 with Earth, reducing it to 0.28% for 2032, down from previous estimates.
➁ The space agency initially estimated a 1.3% chance of collision in 2032, which was then increased to 2.3% and then to 3.1% after follow-up observations.
➂ The latest observations have decreased the impact probability to just 0.28%.
➀ Researchers mistakenly identified Elon Musk's Tesla Roadster as a near-Earth asteroid.
➁ The error was corrected within a day after realizing the object's orbit matched the Falcon Heavy Upper stage with the Tesla Roadster attached.
➂ The incident highlights the need for accurate tracking of space objects and the challenges faced due to the lack of a centralized database.
➀ Elon Musk announced that President Trump requested SpaceX to return two astronauts from the ISS due to concerns with Boeing's Starliner.
➁ NASA astronauts Butch Wilmore and Suni Williams have been stuck on the ISS since June 2024 after arriving on the Boeing Starliner spacecraft.
➂ NASA decided that they would come home on Dragon after uncertainties surrounding Starliner.
➀ NASA's Hubble Space Telescope captured a 2.5 billion-pixel image of the Andromeda galaxy, our closest neighbor, set to collide with the Milky Way in 4.5 billion years.
➁ The image is a result of over 10 years of work, consisting of approximately 600 different fields of view of Andromeda.
➂ The image captures 200 million stars and provides a detailed view of Andromeda almost edge-on, giving insights into the structure and evolution of spiral galaxies.
➀ This weekend, a partial solar eclipse will occur, with maximum coverage happening between 6:30 a.m. EST and 7:05 a.m. EST, depending on location.
➁ The Moon will pass in front of the Sun, casting a shadow on parts of the Northern Hemisphere, but no total solar eclipse will be visible this time.
➂ Proper eye protection, such as solar viewing glasses, is essential for safely observing the eclipse.
➀ Neil Armstrong, the first man on the moon, spoke at the 2006 Freescale Technology Forum, downplaying the significance of his 'giant step for mankind'.
➁ Armstrong discussed the risks involved in the moon landing, including the computer system disagreement during the final approach and landing.
➂ He recounted the first experiment on the moon, which was to set up mirrors for laser measurements, and humorously mentioned the challenge of correctly determining the location of Mount Hamilton.
➀ NASA正在展示其在星座自主卫星测试方面的进展,使用名为分布式航天器自主(DSA)的技术;
➁ 目标是让单个航天器能够独立做出决策,同时与其他航天器协作;
➂ 长期目标是提高多航天器任务的适应性,通过分布式空间任务中的临时网络有效地分配任务。
➀ The U.S. Defense Advanced Research Projects Agency (DARPA) has selected two research teams, the University of Illinois Urbana-Champaign and Caltech, to advance in-space manufacturing under the NOM4D programme.
➁ The third and final phase of NOM4D will involve orbital demonstrations to evaluate materials and assembly processes in space.
➂ The NOM4D programme aims to overcome space cargo constraints and enable in-orbit construction of larger and more mass-efficient structures.
➀ NASA的SPHEREx太空望远镜在完成环境测试后在科罗拉多州博尔德的BAE系统公司进行了拍摄;
➁ 该望远镜由BAE系统公司制造,韩国天文学和空间科学研究所提供了非飞行低温测试室;
➂ SPHEREx的目的是进行首次全天空光谱调查,收集超过4.5亿个星系和1亿颗银河系恒星的数据,以探索宇宙的起源。
➀ The ISS National Lab releases its annual report detailing research conducted on the International Space Station (ISS) over the past year.
➁ The report highlights 103 payload deliveries sponsored, resulting in 51 published, peer-reviewed papers.
➂ The majority of payloads were from commercial entities, with 75% of new projects coming from new-to-space users.
