欧洲太空总署（ESA）的尤克里德（Euclid）太空望远镜捕捉到了银河系中心隆起处（galactic bulge）有史以来最大且最详细的可见光图像。这张由九张曝光照片拼贴而成的图像包含了超过6,000万颗恒星、星云和星团，是尤克里德望远镜在短短26小时的观测中完成的。

虽然尤克里德的设计初衷是观测遥远的星系，但其可见光相机非常灵敏，能够在不被强光淹没的情况下解析出银河系中心恒星密集的个别天体。这些观测数据虽然短暂，但它建立了一个宝贵的历史档案，为未来的微重力透镜观测提供了基线对照。

尤克里德所记录的恒星数据，能与即将发射的罗曼太空望远镜（Nancy Grace Roman）等未来任务协同作业。科学家们将利用尤克里德过去的观测图像作为时间基准，来确认新发现的系外行星并更精确地测量其质量，同时也能研究棕矮星、双星及星系尘埃等。

The European Space Agency's (ESA) Euclid space telescope has captured the largest and most detailed visible-light image ever obtained of the Milky Way's galactic bulge. This mosaic, composed of nine separate exposures captured in just 26 hours of observation, contains more than 60 million stars, along with nebulae and star clusters.

Although Euclid was designed to observe billions of distant galaxies, its sensitive visible-light camera successfully resolved individual stars in the crowded center of our galaxy without being overwhelmed. While this short campaign could not detect new microlensing events directly, it provides a valuable reference archive of the region.

Euclid's historical observations will serve as a baseline for future missions, such as the Nancy Grace Roman space telescope. By comparing future microlensing events with Euclid's data, scientists will be able to confirm exoplanets and measure their masses more precisely, while also supporting research on brown dwarfs and stellar motions.
