魯賓的第一印象射手座天景
Rubin's First Look: A Sagittarius Skyscape

發表日期:2025-06-25
這幅星際天景圖跨越超過 4 度的擁擠星域,朝向人馬座和銀河系中央。這是NSF-DOE 新建的維拉-C-魯賓天文臺(Vera C. Rubin Observatory)拍攝的一張 "第一視角 "照片,照片中明亮的星雲和星團包括了宇宙望遠鏡之旅的著名站點:Messier 8 和Messier 20 。Messier 8 是一個直徑超過 100 光年的廣闊恆星形成區,也被稱為礁湖星雲。大約 4000 光年外的礁湖星雲蘊藏著一個由年輕的大質量恆星組成的非凡星團。它們強烈的輻射和恆星風為這個宇宙礁湖的湍急深處注入了能量,並使其躁動不安。Messier 20 的俗稱是三葉星。三葉星雲被深色的星際塵埃通道分成三部分,熾熱的氫氣形成了它最主要的紅色。但色彩斑斕的三葉星雲中對比鮮明的藍色色調是由於塵埃反射星光造成的。魯賓天文臺在四個晚上( 5 月 1 日至 4 日)的部分時間裡訪問了三葉星雲-礁湖區域,獲取了所有影像資料。在全解析度下,魯賓的壯麗人馬座天景寬 84 , 000 畫素,高 51 , 500 畫素。
原文: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.
