Alright, they'd warp into the system and find that this batch of Gallium is more unstable then previously thought, and may need more processing then originally planned to make it safe. However, it'll also improve its' usability as a missile enhancing material. The Pulsating energy signature appears to be an artificial structure and is roughly 2km wide, 1km long. Roughly circular. The Orb appears to be coming through the nebula a bit faster then expected, shaving off four months from it's 24 month arrival date.

Everyone else warping into the system would also learn the same things, and soon notice each-other.
