在遙遠的宇宙中,有一個叫做南方皇冠(Corona Australis)的地方,它就像一個閃耀的寶石盒,裡面有很多年輕和古老的星星。這裡有一個特別的雲,稱為南方皇冠雲,裡面充滿了發光的氣體和奇妙的星星。這個雲距離我們的地球很近,大約430光年,它是最接近我們的星星形成區域之一。這些氣體是如此寒冷,讓它們能夠凝聚成新的恆星。那些剛剛形成的恆星用藍色的光輝照亮了這片雲朵,彷彿在給它們的小夥伴們講故事。南方皇冠雲中有一對恆星形成的二元系統叫作R Coronae Australis,它們的一顆星星用紫外光照射附近的氣體,讓它們發出美麗的光芒。在雲的右上方,有一個叫做燭台星團(NGC 6723)的地方,雖然它看起來很近,但實際上卻距離我們十幾萬光年哦!燭台星團裡的恆星已有很多年,它們像閃亮的小燭台,為我們的宇宙增添了一份驚艷的美麗。
原文:
The Southern Crown (Corona Australis) dazzles with young and ancient celestial jewels. The Corona Australis Cloud is a collage of reflection and emission nebulae on the left of today’s image. At 430 light years away, this cloud is one of the closest star-forming regions to Earth. It contains gas cool enough (-260 Celsius or -440 Fahrenheit) to collapse into protostars. Recently formed stars paint blue hues across the cloud as their light reflects off surrounding material. The waltz of the R Coronae Australis binary system stirs up the nebula NGC 6729. The younger of the pair ionizes nearby gas with its ultraviolet light, causing it to glow. The Chandelier Cluster (NGC 6723) dangles from the top right, but is actually tens of thousands of light years farther away than its apparent star-forming neighbor. While NGC 6723 experienced multiple periods of star formation creating slightly younger stars, the chandelier twinkles with stars almost as old as the universe.
