🌌 這幅星際天空景色橫跨超過4度,映襯著繁星密布的星空,朝向人馬座及銀河的中央。這幅首度曝光的影像是由美國國家科學基金會(NSF)及美國能源部(DOE)所建造的維拉·C·魯賓天文台捕捉的,畫面中亮眼的星雲和星團包括了天文觀測的著名景點:梅西耶8(Messier 8)和梅西耶20(Messier 20)。
梅西耶8,也被稱為「潟湖星雲」(Lagoon Nebula),是一個超過一百光年的廣闊恆星形成區,距離地球約4,000光年。這裡擁有一群年輕而巨大的恆星,其強烈的輻射和恆星風能量激發並攪動著這個宇宙潟湖的炸煉深處。梅西耶20的流行名稱是「三裂星雲」(Trifid Nebula)。由於黑暗的星際塵埃帶將其分成三部分,三裂星雲中發光的氫氣創造了其主導的紅色。但是,由於塵埃反射恆星光線而形成的對比藍色,為色彩豐富的三裂星雲增添了其他色調。
魯賓天文台在四晚(5月1日至4日)中造訪了三裂-潟湖區域,以獲得影像數據。在全解析度下,魯賓的壯麗人馬座天空景色寬達84,000像素,高達51,500像素。

This interstellar skyscape spans over 4 degrees across crowded starfields toward the constellation Sagittarius and the central Milky Way. A First Look image captured at the new NSF–DOE Vera C. Rubin Observatory, the bright nebulae and star clusters featured include famous stops on telescopic tours of the cosmos: Messier 8 and Messier 20. An expansive star-forming region over a hundred light-years across, Messier 8 is also known as the Lagoon Nebula. About 4,000 light-years away the Lagoon Nebula harbors a remarkable cluster of young, massive stars. Their intense radiation and stellar winds energize and agitate this cosmic lagoon’s turbulent depths. Messier 20’s popular moniker is the Trifid. Divided into three parts by dark interstellar dust lanes, the Trifid Nebula’s glowing hydrogen gas creates its dominant red color. But contrasting blue hues in the colorful Trifid are due to dust reflected starlight. The Rubin Observatory visited the Trifid-Lagoon field to acquire all the image data during parts of four nights (May 1-4). At full resolution, Rubin’s magnificent Sagittarius skyscape is 84,000 pixels wide and 51,500 pixels tall.
