The European Space Agency's Euclid telescope has taken a high-quality image of the Milky Way's galactic bulge. This image will help prepare for future observations by NASA's Nancy Grace Roman Space Telescope.

歐洲太空總署的 Euclid 望遠鏡拍攝了一張銀河系核球的高品質影像。這張影像將有助於 NASA 的 Nancy Grace Roman 太空望遠鏡進行未來的觀測準備。

The Euclid mission was originally created to study dark matter and dark energy. However, in March 2025, it spent 26 hours observing the center of our galaxy. This resulted in a set of nine images showing about 60 million stars. Although Euclid's images are not as deep as the data the Roman telescope will provide, the resolution is similar. Consequently, using both sets of data allows scientists to have a two-year head start before the Roman survey begins in 2027.

Euclid 任務最初是為了研究暗物質與暗能量而創建的。然而，在 2025 年 3 月，它花費了 26 小時觀察我們銀河系的中心。這產生了一組包含約 6000 萬顆恆星的九張影像。雖然 Euclid 的影像不像 Roman 望遠鏡將提供的數據那樣深，但解析度相近。因此，使用這兩組數據讓科學家在 2027 年 Roman 巡天調查開始前，能提前兩年做好準備。

This collaboration focuses on a process called gravitational microlensing. This happens when a heavy object bends light, making a distant star appear brighter. By combining data from both telescopes, astronomers can find isolated black holes and 'rogue planets' that do not orbit any star. Furthermore, by comparing Euclid's early images with Roman's future images, researchers can more accurately calculate the mass and movement of these objects. This partnership also helps scientists distinguish between different types of star systems and improve their maps of the Milky Way.

這次合作聚焦於一個稱為「微引力透鏡」的過程。當一個重物使光線彎曲，使遙遠的恆星看起來更亮時，就會發生這種現象。透過結合兩座望遠鏡的數據，天文學家可以發現孤立的黑洞以及不繞任何恆星運行的「流浪行星」。此外，藉由將 Euclid 的早期影像與 Roman 未來的影像進行比較，研究人員可以更準確地計算這些物體的質量與運動。這次合作也幫助科學家區分不同類型的恆星系統，並改良銀河系的星圖。

The cooperation between the Euclid and Roman telescopes creates a strong system for astronomical research, making it easier to discover exoplanets and black holes.

Euclid 與 Roman 望遠鏡之間的合作為天文研究建立了一個強大的系統，讓發現系外行星與黑洞變得更容易。

The European Space Agency's Euclid telescope has captured a high-resolution image of the Milky Way's galactic bulge to facilitate future observations by NASA's Nancy Grace Roman Space Telescope.

歐洲太空總署的歐幾里得望遠鏡捕捉了一張銀河系核球的高解析度影像，以利於 NASA 的南希·格レース·羅曼太空望遠鏡後續的觀測。

The Euclid mission, primarily designed for cosmological research into dark matter and dark energy, deviated from its standard survey in March 2025 to conduct a 26-hour observation of the galactic center. This operation resulted in a mosaic of nine images encompassing approximately 5 square degrees, featuring an estimated 60 million stars. While the Euclid imagery is shallower and possesses fewer color channels than the forthcoming Roman data, its resolution is comparable. The integration of these datasets is intended to provide a temporal baseline, effectively extending the Roman Galactic Bulge Time-Domain Survey by two years prior to its scheduled commencement in spring 2027.

歐幾里得任務主要設計用於暗物質與暗能量的宇宙學研究，但在 2025 年 3 月，該任務偏離了標準巡天路徑，對銀河中心進行了 26 小時的觀測。此次操作產生了一組由九張影像組成的馬賽克圖，涵蓋約 5 平方度，包含估計 6,000 萬顆恆星。雖然歐幾里得的影像較淺且色通道少於即將到來的羅曼數據，但其解析度相當。整合這些數據集旨在提供一個時間基準，有效地將羅曼銀河核球時域巡天（Roman Galactic Bulge Time-Domain Survey）在預定於 2027 年春季開始前提前兩年。

Central to this collaboration is the utilization of gravitational microlensing, a phenomenon wherein the mass of a foreground object warps space-time, thereby magnifying the light of a distant background star. The administration of these combined datasets will enable the identification of isolated stellar-mass black holes and rogue planets—objects that lack companion stars and are thus otherwise undetectable. By cross-referencing Euclid's initial snapshots with Roman's repeated imaging of a 1.7-square-degree region, astronomers can more precisely calculate the mass and trajectory of lensing objects. Furthermore, the synergy between the two instruments allows for the differentiation between transiting exoplanets and binary star systems, while simultaneously refining existing models of the Milky Way's structural composition through the observation of stellar kinematics across the galactic plane.

此次協作的核心在於利用重力微透鏡現象，即前景天體的質量會扭曲時空，從而放大遠處背景恆星的光線。透過管理這些組合數據集，將能識別孤立的恆星質量黑洞與流浪行星——這些天體由於缺乏伴星，否則將無法被偵測。藉由將歐幾里得的初始快照與羅曼對 1.7 平方度區域的重複成像進行交叉引用，天文學家可以更精確地計算透鏡天體的質量與軌道。此外，兩種儀器之間的協同作用可區分凌日系外行星與雙星系統，同時透過觀測銀盤上的恆星動力學，精煉現有的銀河系結構組成模型。

The strategic alignment of Euclid and Roman telescope data establishes a framework for coordinated astronomical observations to enhance the detection of exoplanets and black holes.
