From Muppet Wiki

Aughra's Observatory was not only the home to Aughra, but also to the crystal shard when Jen found it. It was here that Jen learned of the Great Conjunction, for as Augrah claimed,

Everything in the heavens is here, moving as the heavens do. This is how to know when... Suns, moons, stars. Yes, the angle of eternity.

The Observatory was destroyed by the Garthim.
