Could the flickering and winking of some stars be a kind of Morse
Code that extraterrestrials are using to communicate across space?
Princeton University astrophysicist Lucianne Walkowicz and her
colleagues are exploring that very question. Her team is using
algorithms to sift data from the space observatory Kepler for flickering
patterns that don't appear to be the result of passing planets,
sunspots, eclipses, or other known reasons. “What would lead us to say
it really is an alien signal?” she asks. “I don’t know, but in my book,
finding things you can’t explain is interesting no matter what it is."
And just to be clear, this has nothing to do with the star twinkling that we see, which is caused by atmospheric turbulence on Earth. Or so they'd like us to think. "Flickering Stars: Could Aliens Be Sending Us Signals?"
