[漢羅] 這寡太空影像攏是假 ê，干焦一張是真 ê

咱敢需要一个假 ê 宇宙？ 嘛是有需要啦！為著欲予咱閣較了解 咱真正 ê 宇宙。 有足濟 天文計畫 想欲了解咱宇宙 ê 性質，所以 to̍h 開始利用 機器人望遠鏡 tī 暗暝翕連紲 ê 影像。 紲落來有較複雜 ê 電腦演算法 會處理這寡數位影像，揣看有 恆星 kah 星系 無，才閣來量 in ê 性質。 為著欲校正這寡演算法，in tī 假 ê 宇宙 內底試驗 假 ê 影像，看是毋是會當揣出這寡刁故意做記號 ê 影像。 這張拼接圖 內底 假影 ê 圖，是學 NASA 逐工一幅天文圖 (APOD) 內底 ê 影像。 是講這 225 張影像內底干焦一張是真 ê，毋知你敢揣 伊 有？ In 已經成功產生假 ê APOD 相片，嘛已經 tī 「這毋是 APOD」ê 網站 kah Twitter 發表矣。 實際上，會當幫贊咱校正資料、了解較遠 ê 宇宙天體 ê，是這寡假 ê 星系。 你會當 tī 這个 「這毋是星系」ê 網站 看著一寡仔。

[English] All of These Space Images are Fake Except One

Why would you want to fake a universe? For one reason – to better understand our real universe. Many astronomical projects seeking to learn properties of our universe now start with a robotic telescope taking sequential images of the night sky. Next, sophisticated computer algorithms crunch these digital images to find stars and galaxies and measure their properties. To calibrate these algorithms, it is useful to test them on fake images from a fake universe to see if the algorithms can correctly deduce purposely imprinted properties. The featured mosaic of fake images was created to specifically mimic the images that have appeared on NASA’s Astronomy Picture of the Day (APOD). Only one image of the 225 images is real – can you find it? The accomplished deceptors have made available individual fake APOD images that can be displayed by accessing their ThisIsNotAnAPOD webpage or Twitter feed. More useful for calibrating and understanding our distant universe, however, are fake galaxies – a sampling of which can be seen at their ThisIsNotAGalaxy webpage.
