Here’s a quick rundown of this week in science . . .

1.  In space news:  NASA wants to build a hover-train on the Moon.  And a team at M.I.T. says three of the oldest stars in the universe are in our very own galaxy.

2.  In alien news:  A study found at least seven nearby stars could be surrounded by Dyson spheres.  They’re theoretical megastructures an advanced civilization would build around their star to harness its energy.  The seven stars behave oddly, but there are also other explanations that might be more likely.
