[漢羅] NGC 1850:銀河內底揣無--ê
咱銀河系內底是揣無這款星團。 拄影著這張影像 ê 時陣,會感覺講 這張相片 實在是予人感覺足驚喜--ê。 這張相片是 Hubble 太空望遠鏡 翕著 ê 星團 NGC 1850。 伊 ê 寸尺 kah 外形 hŏng 聯想著 tī 咱 銀河系 銀暈 內底 賴賴趖、古早時代 就有 ê 球形 星團。 毋過 NGC 1850 內底 ê 恆星攏傷少年矣,按呢這款星團就 kah 咱銀河內底 ê 星團 無仝。 而且,NGC 1850 是一个 雙星團。 第二位成員就 tī 這个大陣星團中心倚正爿遐,是一个實密 ê 星團。 這个大陣星團內底 ê 恆星,照估計差不多才 5000 萬歲爾爾。 實密星團內底 ê 恆星是閣較少年,才 400 萬歲爾爾。 NGC 1850 kah 咱 ê 距離才 16 萬 8000 光年 爾爾,伊就 tī 大麥哲倫星雲 ê 星系外沿附近。 影像倒爿規片咧發光 ê 氣體絲,較成是咱銀河內底 ê 超新星殘骸。 In 會經過較激烈 ê 恆星爆炸 階段。 這暗示講,in 是較短命 ê 懸質量 恆星,是最近才出現 tī 這區。

[English] NGC 1850: Not Found in the Milky Way
There is nothing like this ball of stars in our Milky Way Galaxy. This is surprising because, at first glance, this featured image by the Hubble Space Telescope suggests that star cluster NGC 1850's size and shape are reminiscent of the many ancient globular star clusters which roam our own Milky Way Galaxy's halo. But NGC 1850's stars are all too young, making it a type of star cluster with no known counterpart in the Milky Way. Moreover, NGC 1850 is also a double star cluster, with a second, compact cluster of stars visible here just to the right of the large cluster's center. Stars in the large cluster are estimated to be 50 million years young, while stars in the compact cluster are younger still, with an age of about 4 million years. A mere 168,000 light-years distant, NGC 1850, is located near the outskirts of the Large Magellanic Cloud galaxy. The glowing gas filaments across the image left, like supernova remnants in our own galaxy, testify to violent stellar explosions and indicate that short-lived massive stars have recently been present in the region.
