✨近日,一組研究人員透過哈勃太空望遠鏡,構建了有史以來最大幅的仙女座星系圖像,名為「Panchromatic Hubble Andromeda Treasury (PHAT)」。這幅圖像搜集了數千次觀測,涵蓋了星系的三分之一,並解決了超過一億顆星星的細節。圖像左側顯示了星系的中央部分,而右側則醒目展示了一條藍色的螺旋臂。
有趣的是,畫面中最亮的星星實際上是我們銀河系的前景恒星。PHAT數據正被深入分析,以更好地理解M31中的恒星形成過程,並與我們的銀河系作比較,還有助於識別和描述仙女座的恆星團和遮擋塵埃。

What stars compose the Andromeda galaxy? To better understand, a group of researchers studied the nearby spiral by composing the largest image ever taken with the Hubble Space Telescope. The result, called the Panchromatic Hubble Andromeda Treasury (PHAT), involved thousands of observations, hundreds of fields, spanned about a third of the galaxy, and resolved over 100 million stars. In the featured composite image, the central part of the galaxy is seen on the far left, while a blue spiral arm is prominent on the right. The brightest stars, scattered over the frame, are actually Milky Way foreground stars. The PHAT data is being analyzed to better understand where and how stars have formed in M31 in contrast to our Milky Way Galaxy, and to identify and characterize Andromeda’s stellar clusters and obscuring dust.
