Your Christmas decorations are WEAK unless someone can spot them from the International Space Station.  A new study calculated how many Christmas lights you’d need to be visible from SPACE.  And the answer isn’t THAT high . . . it’s 2,683 bulbs.

But, there’s a catch.  You would need to be in a dark area, without a lot of light pollution, like the middle of a desert.  If you’re in a more crowded area, it would be a lot harder for someone in space to notice your lights.
