TelescopesWhen placed it will function as a general background tile. But when you interact with a telescope, it will allow you to view the farther stars and planets of the Terraria universe.
Interaction:Interacting with the telescope at night will allow to look into the skies of the Terraria universe. You can use your mouse and drag around to explore what the Terraria universe has to offer. Clicking on a star will allow you to see it's name, what type of star it is, etc. You can also zoom in farther to inspect other planets, sometimes even being your other Terraria worlds that you generated. You could even look for other galaxies if you zoom out far enough!
