This time, a new generation of scientists had the tantalizing yet daunting task of summing up humanity to an extraterrestrial audience.<\/p>\n<p class=\"EkqkG nlgHS yuUao lqtkC TjIXL aGjvy\">A team of then undergraduate students from the University of Puerto Rico at Mayaguez won the contest and took cues from the original message, using the same binary digit system and a similar schematic of the solar system as they drafted a new one. \u201cWe were inspired by the original,\u201d says team member Kelby Palencia-Torres of Toa Alta.<\/p>\n<p class=\"EkqkG nlgHS yuUao lqtkC TjIXL aGjvy\">To expand on the previous communication, the team also included a map that pinpoints the location of Earth within the Milky Way galaxy and highlights some of the interesting cosmic objects in our solar system, such as Saturn\u2019s rings and our lunar companion. (Of course, they updated the solar system to exclude Pluto from the planets depicted.) The proposed transmission also features physical constants like Planck\u2019s constant and the speed of light, as well as basic mathematical operators.<\/p>\n<p class=\"EkqkG nlgHS yuUao lqtkC TjIXL aGjvy\">The original message included information about DNA and amino acids, which some argue could be sensitive information to disclose to potentially predatory aliens. This time around, the team kept information about humans at a minimum, only including a visual representation of humans with average height and the world\u2019s population.<!-- -->\u00a0<\/p>\n<div class=\"oLzSq QrHMO fnRUo pvsTF EhJPu vPlOC zNYgW OsTsW RMeqy daRVX ISNQ sKyCY eRftA acPPc MENS nFwaT MCnQE mEeeY SmBjI xegrY rPLsU iulOd NIuqO zzscu lzDCc aHUBM IEgzD OjMNy eQqcx SVqKB GQmdz jaoD VWDdR ONJdw vrZxD OnRTz gbbfF roDbV GPGwb oMlSS gfNzt oJhud eXZcf zhVlX \">\n<div class=\"lqtkC glxIO HfYhe vUYNV \">\n<div data-testid=\"prism-static-embed\" role=\"region\">\n<div class=\"nMMea bNYiy Mjgpa dGwha DDmxa jgKNG RGHCC aBIU PriDW lZur vUYNV glxIO tSkSq Tora iSjrl \" data-testid=\"prism-caption\">\n<p><span class=\"hsDdd OOSI GpQCA lZur VlFaz \" data-testid=\"prism-truncate\"><span><span aria-hidden=\"false\" class=\"mNSUE OQXzL FWSOf mIlhR jWzcU msTA-d OEkod \">The Music of the Last Arecibo Message<\/span><span class=\"gtOSm FbbUW tUtYa vOCwz EQwFq yCufu eEak Qmvg nyTIa SRXVc vzLa jgBfc WXDas CiUCW kqbG zrdEG txGfn ygKVe BbezD UOtxr CVfpq xijV soGRS XgdC sEIlf daWqJ \">As part of the 50th anniversary celebrations, scientists decided to include a musical component as part of the new message.
