[漢羅] M15:實密 ê 球形星團

M15 是 一个內底有超過 10 萬粒恆星 ê 大型星團。 伊是咱銀河系早期形成活動留落來 ê 殘骸,是超過 130 億歲 ê 其中一个球形星團。 這款銀河內 ê 球形星團差不多有 170 團,到今猶 tī 銀暈內 leh 賴賴趖。 這張是 重新處理過 ê Hubble 影像,中心是 M15,就 tī 飛馬座 方向 3 萬 5000 光年遠 ê 所在。 伊 ê 直徑差不多有 200 光年闊,超過一半 ê 恆星攏集中 tī 中心 10 光年左右 ê 範圍,是目前為止恆星櫼櫼做伙上實密 ê 所在。 Hubble 太空望遠鏡 量著 M15 中心恆星 ê 運動速度是愈來愈緊,證明講有一个 大質量烏洞 tī 這个實密星團中心。 咱閣知影 M15 內底有一个 行星形星雲。 伊就叫做 荷仁豆一星雲 (嘛會使叫做 PN Ps 1),就 tī 這張影像中央正爿下跤彼个藍色光點遐。

[English] M15: Dense Globular Star Cluster

Messier 15 is an immense swarm of over 100,000 stars. A 13 billion year old relic of the early formative years of our galaxy it's one of about 170 globular star clusters that still roam the halo of the Milky Way. Centered in this sharp reprocessed Hubble image, M15 lies some 35,000 light-years away toward the constellation Pegasus. Its diameter is about 200 light-years, but more than half its stars are packed into the central 10 light-years or so, making one of the densest concentrations of stars known. Hubble-based measurements of the increasing velocities of M15's central stars are evidence that a massive black hole resides at the center of the dense cluster. M15 is also known to harbour a planetary nebula. Called Pease 1 (aka PN Ps 1), it can be seen in this image as a small blue blob below and just right of center.
