[漢羅] 球形星團 杜鵑 47

球形星團 杜鵑 47 是南半球 ê 珠寶。 伊 嘛叫做 NGC 104，kah 其他 200 个 球形星團，做伙 tī 咱銀河系 ê 銀暈內底咧散步。 杜鵑 47 是咱地球天頂第二光 ê 球形星團，比 半人馬座 Omega 較暗，離咱有 1 萬 3000 光年遠。 咱會當直接用目睭 tī 杜鵑座 方向 ê 小麥哲倫星雲 附近揣著伊。 這个實密 ê 星團是幾若十萬粒 恆星 組成--ê，伊 ê 大細差不多是 120 光年闊。 Tī 這張 清楚 ê 望遠鏡影像 內底，咱會當真簡單就揣著 紅巨星，in 就是星團外圍彼寡反黃 ê 恆星。 懸密度 ê 球形星團 杜鵑 47，其中有一粒恆星踅中央烏洞咧行 ê 軌道，是目前為止咱知影 kah 烏洞距離上倚--ê。

[English] Globular Star Cluster 47 Tuc

Globular star cluster 47 Tucanae is a jewel of the southern sky. Also known as NGC 104, it roams the halo of our Milky Way Galaxy along with some 200 other globular star clusters. The second brightest globular cluster (after Omega Centauri as seen from planet Earth, 47 Tuc lies about 13,000 light-years away. It can be spotted with the naked-eye close on the sky to the Small Magellanic Cloud in the constellation of the Toucan. The dense cluster is made up of hundreds of thousands of stars in a volume only about 120 light-years across. Red giant stars on the outskirts of the cluster are easy to pick out as yellowish stars in this sharp telescopic portrait. Tightly packed globular cluster 47 Tuc is also home to a star with the closest known orbit around a black hole.
