Hejhej!
I played a small random map against AI and suddenly got the star explorer bagde. I'm pretty sure that:
- this happened way after one of my ships entered the stars gravwell (which shouldn't trigger the achivement anyway, since i'm supposed to travel to another star right?)
- I didn't research the phase-jump-to-another-star-technology
- and didn't find the phase-jump-to-another-star-enhanching artifact
