這个視野中心 ê 恆星 to̍h 叫做 2MASS J17554042+6551277。 這實在是有夠歹讀 ê，毋閣這就是伊 ê 名，是用座標來做伊 ê 目錄編號。 愛好遙遠宇宙 ê 迷眾，應該已經慣勢伊尖尖 ê 形體矣。 這个繞射圖樣是 18 塊 六角鏡 鬥--出來 ê James Webb 太空望遠鏡 (JWST) 產生 ê。 Kā 摺--起來 ê 望遠鏡拍開了後，逐塊細塊鏡會 調整到紅外線波段需要 ê 繞射極限，予 in 有法度當做是一塊直徑 6.5 公尺闊 ê 主鏡 來運作。 Ùi 這个 Webb 望遠鏡 ê 近紅外線 kha-mé-lah (NIRcam) 翕 ê 相片看會出來，in 對齊 ê 精確度已經到目前 ê 物理極限 矣。 2MASS J17554042+6551277 離咱才 2000 光年遠爾爾，猶 tī 咱 ê 銀河系內底。 毋閣 tī Webb 望遠鏡 leh 做對齊評估 ê 影像內底，背景彼寡星系可能有幾若十億光年遠，彼 to̍h 比咱銀河閣較遠 矣。

[English] 2MASS J17554042+6551277

2MASS J17554042+6551277 doesn't exactly roll off the tongue but that's the name, a coordinate-based catalog designation, of the star centered in this sharp field of view. Fans of the distant universe should get used to its spiky appearance though. The diffraction pattern is created by the 18 hexagonal mirror segments of the James Webb Space Telescope. After unfolding, the segments have now been adjusted to achieve a diffraction limited alignment at infrared wavelengths while operating in concert as a single 6.5 meter diameter primary mirror. The resulting image taken by Webb's NIRcam demonstrates their precise alignment is the best physics will allow. 2MASS J17554042+6551277 is about 2,000 light-years away and well within our own galaxy. But the galaxies scattered across the background of the Webb telescope alignment evaluation image are likely billions of light-years distant, far beyond the Milky Way.
