Rover captures light source on Mars!!

Just thinking about these "gamma ray bursts."

Okay, so maybe that's what they were. But how come we don't still see them? Where are they now? Seems kind of funny that they would just pop up for a short while, all bright and shiny as you please, but now they're nowhere to be seen on any of the images.

Just pondering that. Sometimes the lack of something is also evidence.
