Re. aliens
Its just possible that the alien spaceship *might* be hiding behind Pluto doing repairs on its drive as X-ray emissions are one known side effect of a leaking primary intercoolant system.
As we lack the technology to help out much (this assumes it is an experimental craft and lacks shuttles with more than a 5M km range) about all we can do is send them a signal wishing them luck.
Disclaimer: I used to fix these back in '47 when they still used good old fashioned cryogenic superconductors on the drive pods not these new fangled quantum slipstream things which no-one fully understands but uses them anyway because they get 30,000,000,000N/kW and travel 0.5LY/hr.
I wonder if they've detected the emissions from New Horizons? It can't be that far away by now, although traveling quite fast its possible they could do a free return trajectory and "borrow" its RTGs.
