Considering that M13 is actually 25,000 light-years away, it will certainly take 25,000 years for any sort of M13 invaders to hear our notification– if they are actually flatten there certainly. The Arecibo information is just one of several notifications intended for space beings. We have actually additionally consisted of messages on several space capsule, such as Trailblazer as well as Voyager.
