[漢羅] 哈伯影像：木星 kah 變細粒 ê 大紅斑

木星 ê 大紅斑會變做啥款？ 木星 這粒氣態巨行星是太陽系內底上大粒 ê 行星。 伊 ê 質量是 地球 ê 320 倍大。 木星是目前咱知影太陽系內底有上大、上久風暴系統 ê 行星。 就是倒爿你看著 ê 彼粒 大紅斑。 大紅斑 大到比地球閣較大，就算講伊這馬變較細粒矣，猶是較大。 若是 kah 歷史記錄比起來，這个 風暴 干焦 150 年前 ê 1/3 大爾爾。 NASA ê 外行星大氣遺產 (OPAL) 計畫，最近一直咧用 哈伯太空望遠鏡 監看這个風暴。 這張哈伯 OPAL 影像 是 2016 年 ê 木星，毋閣色調有處理過，才會予紅色變較明顯。 咱 ùi 現代 大紅斑資料知影，風暴區是愈來愈細，毋閣伊嘛 tī 坦徛方向變 較懸淡薄仔。 無人知影這粒 大紅斑 未來會變按怎，嘛毋知是毋是會繼續 變閣較細。 若是按呢，大紅斑有一工可能會 完全變無去。

[English] Hubble's Jupiter and the Shrinking Great Red Spot

What will become of Jupiter's Great Red Spot? Gas giant Jupiter is the solar system's largest world with about 320 times the mass of planet Earth. Jupiter is home to one of the largest and longest lasting storm systems known, the Great Red Spot (GRS), visible to the left. The GRS is so large it could swallow Earth, although it has been shrinking. Comparison with historical notes indicate that the storm spans only about one third of the exposed surface area it had 150 years ago. NASA's Outer Planets Atmospheres Legacy (OPAL) program has been monitoring the storm more recently using the Hubble Space Telescope. The featured Hubble OPAL image shows Jupiter as it appeared in 2016, processed in a way that makes red hues appear quite vibrant. Modern GRS data indicate that the storm continues to constrict its surface area, but is also becoming slightly taller, vertically. No one knows the future of the GRS, including the possibility that if the shrinking trend continues, the GRS might one day even do what smaller spots on Jupiter have done -- disappear completely.
