[漢羅] Trappist-1 ê 第七粒行星

有 7 粒行星踅這粒足低溫度 ê 矮星 TRAPPIST-1 咧行。 In 離咱才 40 光年 遠爾爾，這个系統內底大部份 ê 行星攏是 2016 年彼陣 用 摩洛哥 Atlas 山頂 ê 凌星行星佮原行星小望遠鏡 (TRAPPIST) 揣著了後，閣用其他天文望遠鏡，親像是 NASA ê Spitzer 紅外線太空望遠鏡 確認--ê。 TRAPPIST-1 ê 行星 應該攏是 kah 地球差不多大細 ê 岩石行星。 因為這粒恆星有 遮爾濟粒 類地行星 踅伊 leh 行，所以遮就變做是一个上大 ê 寶庫矣。 雖罔講 in ê 母星是一粒細粒閣暗 ê 恆星，毋過因為 in ê 公轉軌道 kah 母星是足倚--ê，所以 in ê 表面溫度懸甲 毋但會揣著冰、甚至有可能揣著液態水。 這是 tùi 性命 來講足重要 ê 成分。 因為 in kah 地球是 遮爾倚，所以 in 就變做科學家 未來欲用天文望遠鏡 探索 合蹛區 ê 系外行星 大氣 上重要 ê 候選天體 矣。 這張插畫有 kā 這 7 粒 系外行星 攏畫出來。 這是一張 ùi 這个系統內底上遠彼粒行星 TRAPPIST-1h 看--著 ê 想像圖。 這粒行星有岩石 ê 地景，表面有崁一重冰。 而且，背景 ê 景色內底，拄仔好有一粒 內行星 ùi 伊 ê 母星面頭前行過。 這粒柑仔色 ê 母星毋是蓋光，大細 kah 木星 差不多大。

[English] The Seventh World of Trappist-1

Seven worlds orbit the ultracool dwarf star TRAPPIST-1. A mere 40 light-years away, many of the exoplanets were discovered in 2016 using the Transiting Planets and Planetesimals Small Telescope (TRAPPIST) located in the Atlas Mountains of Morocco, and later confirmed with telescope including NASA's Spitzer Space Telescope. The TRAPPIST-1 planets are likely all rocky and similar in size to Earth, and so compose one of the largest treasure troves of terrestrial planets ever detected around a single star. Because they orbit very close to their faint, tiny star they could also have regions where surface temperatures allow for the presence of ice or even liquid water, a key ingredient for life. Their tantalizing proximity to Earth makes them prime candidates for future telescopic explorations of the atmospheres of potentially habitable planets. All seven exoplanets appear in the featured illustration, which imagines a view from the most distant known world of this system, TRAPPIST-1h), as having a rocky landscape covered in ice. Meanwhile, in the imagined background, one of the system's inner planets crosses in front of the dim, orange, nearly Jupiter-sized parent star.
