Ex Gravitas

A base of operations has been set up on the surface of the moon, and several teams are now en route to the various anomaly sites that our scanners picked up.

The significance of this mystery is simply unparalleled, and the scientific community is absolutely buzzing with theories and anticipation over what will be uncovered by the excursion teams.

Most excursion teams have reached their destinations and reported back.

Artifacts buried in the ground have been uncovered. Head Scientist … describes them as highly accurate, galactic laser pointers - ancient machines that are emitting a strong, tight ultraviolet beam out into space for purposes unknown.

It's a bittersweet discovery; the profound, exhilarating importance of alien artifacts countered by their seemingly arbitrary purpose.

Despite our best efforts the excavation and analysis of the alien indicators on the surface have failed to deliver any relevant result.

The archaeological teams have calculated and followed the paths of the alien signal beams, but nothing is being pointed at other than empty space.

Scientist … have requested more time; convinced that something has been missed by the science teams.

Breakthrough!

Study of the surface revealed that the moon was hit eons ago by a small asteroid. The impact was not enough to obliterate the moon but did nudge it a fraction out of its original orbit. By analyzing the impact, the scientists managed to calculate the moon's initial position and rotation, and used that data to 'rewind' the alien indicators to their original position.

And there it was: the alien indicator beams suddenly began converging on another planet in the system!
