[漢羅] LHS 475 b：地球大細 ê 系外行星

你若是會當徛 tī 系外行星 LHS 475 b 頂懸，你會看著啥毋？ 無人知影。 毋過這張利用地球 ê 人工智慧 (AI) iăn-jín 畫 ê 相片 是足趣味--ê，會當予你想像一下。 科學家 ùi 踅地球 ê TESS 衛星望遠鏡 提著 ê 資料，推測講有 系外行星 ê 存在。 毋過一直到今年才 ùi 飛 tī 地球附近 踅太陽 ê James Webb 太空望遠鏡 (JWST) 提著 ê 資料，證實這件代誌，嘛才通做進一步 ê 研究。 咱這馬已經知影 ê 是，LHS 475 b 是一粒 kah 咱地球 質量差不多 ê 行星。 伊 ê 母恆星是一粒 細粒 ê 紅矮星，離咱有 40 光年遠。 伊踅母恆星 ê 軌道離母恆星是足倚--ê。 這張 AI 畫 ê 插畫，畫出一个 kah 地球足成--ê、坎坎坷坷 ê 地景，毋過這个世界攏是 熔岩。 後壁彼粒是紅色 ê 母恆星，tī 遠方 peh 起來。 Webb 望遠鏡 ê 觀測資料猶未公佈，毋過 LHS 475 b 應該是有一重大氣層。 Webb 望遠鏡 ê 其中一个科學目標，就是欲追蹤進前已經發現--ê、遙遠 ê 系外行星，看遐是毋是有可能 發展性命。

[English] LHS 475 b: Earth-Sized Exoplanet

If you could stand on exoplanet LHS 475 b, what might you see? No one knows for sure but pictured here is an interesting guess made by an Earth-based artificial intelligence (AI) engine. The existence of the exoplanet was indicated in data taken by the Earth-orbiting TESS satellite but confirmed and further investigated only this year by the near-Earth Sun-orbiting James Webb Space Telescope. What is known for sure is that LHS 475 b has a mass very similar to our Earth and closely orbits a small red star about 40 light years away. The featured AI-illustrated guess depicts a plausibly rugged Earth-like landscape replete with molten lava and with the central red star rising in the distance. Webb data does not as yet reveal, however, whether LHS 475 b has an atmosphere. One of Webb’s science objectives is to follow up previous discoveries of distant exoplanets to better discern their potential for developing life.
