They can change the colour and texture of their skin. To get an informed guess, I turned to a scientist whose work doesnвЂ™t involve telescopes at all.ДЇrom our human perspective, itвЂ™s hard to find anything on Earth more alien than an octopus. вЂњET, if theyвЂ™re out there, may not have our best interests at heartвЂ¦ Maybe they're more interested in grinding up our planet and just looking for palladium.вЂќДЄnother big question is what those aliens, if they exist, might look like. But that result, Wertheimer tells W5, might be a blessing in disguise. Will the signal from Proxima Centauri be a bust, too? Perhaps. (If you open the door before the bell goes off, apparently that creates an alien-like artifact in the signal). Now the question is whether itвЂ™s the signal weвЂ™ve been waiting for, or whether, like hundreds before it, itвЂ™s just more interference from here on Earth.ДЄfter all, similarly tantalizing signals detected every once in a while since the 1990s, by that very same telescope, were later discovered to be coming from the microwave oven in the lunch room. That 2019 signal from Proxima Centauri was just that вЂ“ a faint whistle. If ET were transmitting, we'd still get the hissing noise from the galaxies and big bang, but also might hear a very faint whistle.вЂќ

It sounds like when you tune your radio TV between channels. вЂњWhen we point our telescopes anywhere in the sky, what we receive sounds like hissing noise (from galaxies and the big bang radiation). Might aliens on that planet have sent the signal? How would we know?Дaniel Wertheimer, an astronomer from the University of California Berkeley, has been scanning radio waves for decades. We know thereвЂ™s a planet orbiting that star. On April 29, 2019, the Parkes Radio Telescope in Australia was pointed at the star closest to our own sun, Proxima Centauri, when it picked up a strange signal. But those same electronic ears built to listen for human-made signals, might someday hear sounds sent by someone else. For example, the farthest spacecraft from Earth, Voyager-1, sent back some haunting signals as it crossed from our sunвЂ™s solar system out into interstellar space. We collect sounds from space all the time in the form of radio waves. For W5, I posed that question to several planetary scientists, astrophysicists, and radio-telescope astronomers who are bringing new tools and techniques to the search for extraterrestrial intelligence (SETI). TORONTO - For millennia, humans have looked up at the night sky, wondering whether alien life exists.
