Yggdrasill, the world tree, is an energy field that supports and connects the Nine Worlds. It is represented as a tree the roots and branches of the tree each connect a different realm such as Asgard, Jotunheim, Muspelheim, Alfheim, Vanaheim, Nidavellir, Svartalfheim, Niffleheim and the earthly realm of Midgard through which all the connections pass. Initially, there were Ten Realms. The lost realm of Heven was cut from Yggdrasil by Odin after the war between Asgard and Heven seemingly cost the life of his newborn daughter Aldrif.
At its base are three wells: Urdarbrunnr (Well of Fate), from which the tree was watered by the Norns (the Fates); Hvergelmir (Roaring Kettle), in which dwelt Nidhogg, the monster that gnawed at the tree’s roots; and Mímisbrunnr (Mimir’s Well), source of wisdom, for the waters of which Odin sacrificed an eye. After Ragnarök, the world tree, though badly shaken, was to be the source of new life.

In Earth-199999, Yggdrasil is as a constellation linking the Nine Realms through a cosmic channel. Thor insists that humans are unaware of the cosmos despite glimpses of the tree's branches appearing through the Hubble Space Telescope's images.
Yggdrasil is seen when Loki used the Norn Stones to link all the Nine Realms which includes Earth. There is also a tree in Odin's throne room representing Yggdrasil, which allowed Loki access to the mystical energy of the universe.
