[漢羅] 昴宿星團：厚塗粉 ê 七姊妹仔星團

有名 ê 昴宿星團 當咧 沓沓仔 消滅 一部份 迵過 伊 ê 氣體 kah 塗粉 。 昴宿星團 是地球天頂上光 ê 開放星團 之一，tī 北半球任何一个所在用 目睭 就 看會著。 Tī 過去 10 萬年內底，有一大片氣體 kah 塗粉拄仔好迵過 昴宿 星團，造成 恆星 kah 塗粉 ê 強烈反應。 這團雲可能是 Radcliffe 波 ê 一部份，是 最近才發現–ê。 伊是 kah 咱 銀河系 附近 幾若个恆星形成區相連 ê 氣體 kah 塗粉結構。 恆星 ê 光壓會排斥四箍圍仔藍色 反射星雲 內底 ê 塗粉。 愈細粒 ê 塗粉，排斥力就愈大。 短期 ê 結果是，一部份 ê 塗粉雲變做 一絲一絲、一重一重。 這張深空影像是舊年 tī 美國 猶他州 ê 猶他沙漠遙控天文台 開 9 點鐘 ê 感光時間翕–ê。

[English] The Pleiades: Seven Dusty Sisters

The well-known Pleiades star cluster is slowly destroying part of a passing cloud of gas and dust. The Pleiades is the brightest open cluster of stars on Earth’s sky and can be seen from almost any northerly location with the unaided eye. Over the past 100,000 years, a field of gas and dust is moving by chance right through the Pleiades star cluster and is causing a strong reaction between the stars and dust. The passing cloud might be part of the Radcliffe wave, a newly discovered structure of gas and dust connecting several regions of star formation in the nearby part of our Milky Way galaxy. Pressure from the stars’ light significantly repels the dust in the surrounding blue reflection nebula, with smaller dust particles being repelled more strongly. A short-term result is that parts of the dust cloud have become filamentary and stratified. The featured deep image incorporates nearly 9 hours of exposure and was captured from Utah Desert Remote Observatory in Utah, USA, last year.
