Nut's Gift (Aaru)
A giant crater in Aaru, right by the entrance.
The location treasure is in a red chest aboard the reedship here. It is possible to approach it stealthily, but a better approach is slaughter every hostile here. This location is brimming over with starmetal shards, and you're going to want to loot the whole place top to bottom.
Use your own animus pulse to locate starmeteal caches in and around the crater. Also, be certain to investigate the large white chest in the orangeish tent close to the ship- it contains 20 shards all on its own.
Once you've stripped the place bare, remember not to leave before looting the red chest amidship, and completing the location.
