[漢羅] Hubble 翕--ê 球形星團 NGC 6355

球形星團 以前 sī 銀河系 上主要 ê 成員。 古早古早 以前，咱銀河 拄形成 ê 時陣，內底差不多有幾若千个球形星團。 今仔日干焦賰無夠 200 个。 Tī 咱銀河過去 ê 歷史，有足濟球形星團 因為一直相拄、抑是行過 銀河中心 附近，煞去予搝散去。 賰 ê 星團遺跡 sī 比 地球 ê 化石 閣較老，嘛比 咱銀河內底任何結構 閣較老。 這會當幫贊咱 揣出 宇宙原始年歲 ê 範圍。 咱 銀河系 內底 ê 少年球形星團 實在 sī 足少--ê，因為 這个環境 無法度形成較濟球形星團。 這張影像 sī 用 Hubble 太空望遠鏡 去看 已經 130 億歲 ê NGC 6355。 伊 sī 目前行過 銀河中心 附近、猶無去予拆散 ê 球形星團。 球形星團內底 ê 恆星攏 集中 tī 影像中心，而且較光 ê 藍色恆星 sī 足明顯--ê。 其他 tī 影像內底較暗、較紅 ê 恆星，只是拄仔好出現 tī NGC 6355 ê 方向附近爾爾。

[English] Globular Star Cluster NGC 6355 from Hubble

Globular clusters once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are less than 200 left. Over the eons, many globular clusters were destroyed by repeated fateful encounters with each other or the Galactic center. Surviving relics are older than any Earth fossil, older than any other structures in our Galaxy, and limit the universe itself in raw age. There are few, if any, young globular clusters left in our Milky Way Galaxy because conditions are not ripe for more to form. The featured image shows a Hubble Space Telescope view of 13-billion year old NGC 6355, a surviving globular cluster currently passing near the Milky Way's center. Globular cluster stars are concentrated toward the image center and highlighted by bright blue stars. Most other stars in the frame are dimmer, redder, and just coincidently lie near the direction to NGC 6355.
