    Please don’t invade us, space invaders! :D

    We should design one of these to send every decade (just to evaluate how we see ourselves, the universe and our place in it)

    Its 23 pixels wide. Not a binary friendly number. If i receive it in a stream, i wouldnt know how to reconstruct the image, even before trying to make sense of the hieroglyphs.

      It’s because both the height and length are prime numbers, to allow the aliens to figure out the expected resolution

      From Wikipedia:

      • white - encoding the numbers 1 to 10 in binary code
      • purple - 1, 6, 7, 8, 15. Atomic numbers of H, C, N, O, P; the five main elements of DNA.
      • green - some atomic formulas for DNA nucleotides
      • white and blue - average human height and Earth population back (4 billions)
      • red - human
      • yellow - Solar system, from Mercury to Pluto
      • purple, white, blue - the telescope sending the signal

      …it’s cute. But frankly, I don’t think even we humans would be able to re-decode it, if we lost the original meaning. There’s simply not enough context to do it.
