LUCA是「最近普適共同祖先」的縮寫，意指地球上現存生命的共同起源。這件作品參考了韋伯太空望遠鏡的觀測成像，以漸變星體及棲居其上的微生物模型，回應宇宙浩瀚無垠的可能性，藉以勾勒與其他物種共存的太空未來。當「太空探索」已不再是空想，人類所能觀測到的「光譜邊界」隨科技進步不斷拓展，也許某天我們將在宇宙某處與同源的太空生命相遇。

“LUCA” is an acronym for "Last Universal Common Ancestor," which refers to the common origin of existing life on Earth. The planetary installation draws on observational imagery of the Webb Space Telescope. It sketches an alternative space future that coexists with other species with models of an evolving planet and microbial inhabits on it in response to the vastness of the universe. When space exploration is no longer a fantasy, human observation's "spectral boundaries" will continue to expand as technology advances. We may one day meet with space life of the shared origin somewhere in the universe.
