[漢羅] Green Bank 天文台頭頂 ê 獵戶座

遮爾大台 ê Green Bank 望遠鏡下暗會 tī 天頂發現啥物？ 相片倒爿下跤 ê 是 Robert C. Byrd Green Bank 望遠鏡 (GBT)，是世界 上大 ê 全指向 單接收盤 電波望遠鏡。 GBT ê 中央接收盤是比跤球場閣較大。 伊 tī 美國 ê 西 Virginia 州 ê 一个山頂，遐是一个 電波禁止區，袂當用電話 kah WiFi，連電磁爐嘛袂當用。 GBT 毋若 tī 暗時探索咱 ê 宇宙，日時嘛 leh 看。 因為 ùi 電波波段 來看，日時嘛是烏-mih-mà。 這張相片是 tī 一月底翕 ê。 這个構圖已經計畫幾若個月矣，是欲予 獵戶座 出現 tī 畫面 ê 正手爿。 這張相片是 kā 前景 kah 背景分開翕了 了後，才閣 kā 疊做一張 ê。 前景是 tī GBT 頭前幾若公里遠 ê 所在翕 ê，背景是前一暝用長時間感光翕 ê。 背景 ê 深空影像 獵戶座 kah GBT 實在是 足合 ê。 這是因為 tī 足濟 kah 獵戶座有關 ê 研究內底，GBT 上有名 ê 就是 kā 獵戶座分子雲複合體 無四常 ê 磁場 畫出來。

[English] Orion over Green Bank

What will the huge Green Bank Telescope discover tonight? Pictured, the Robert C. Byrd Green Bank Telescope (GBT) on the lower right is the largest fully-pointable single-dish radio telescope in the world. With a central dish larger than a football field, the GBT is nestled in the hills of West Virginia, USA in a radio quiet zone where the use of cell phones, WiFi emitters, and even microwave ovens are limited. The GBT explores our universe not only during the night – but during the day, too, since the daytime sky is typically dark in radio waves. Taken in late January, the featured image was planned for months to get the setting location of Orion just right. The image is a composite of a foreground shot taken over a kilometer away from the GBT, and a background shot built up of long exposures during the previous night. The deep background image of Orion is fitting because the GBT is famous for, among many discoveries, mapping the unusual magnetic field in the Orion Molecular Cloud Complex.
