Light Shaft
From Wikitroid, the Metroid wiki
A Light Shaft is a beam of light that appears at the different temples on Aether. They allow Samus, once she has acquired the Light Suit, to quickly travel from one temple to another along the shafts from the Light of Aether. These transports are instantaneous, and link all four temples.
Four other light shafts also appear other areas. These "lesser" shafts merely carry Samus to a different spot in the room it's in, rather than transporting her across the whole map. One is in the room in the Temple Grounds that allows access to the elevator to Sanctuary Fortress, which allows Samus to reach a hidden Energy Tank. Another is in the map room for Sanctuary Fortress, which leads to a Missile Expansion. There is another one in the Ing Hive, at the Dark Aether version of the entrance to Sancutary Fortress, which is used to get one of the Sky Temple Keys. The final one is in the Sky Temple Gateway. This one is more like the main Light Shafts, as it links up to the Sky Temple rather than just moving you around the room, though its magnitude is far less than the four main shafts.
