The following article shares highlights and insights from one of our Expert Series events, which are exclusive for Young Scholars and their parents.
Thanks to the Kepler Telescope, we now know that there are many Earth-like planets in our galaxy. Some of them are even called Super-Habitable Earths – meaning that the conditions on those planets may be more suitable for life than here on Earth, believe it or not. What is the possibility that there are other intelligent civilizations in our Universe, then? And if there are any, could we communicate with them?
Lots of astrobiologists are thinking about these problems. A while ago, astronomer Frank Drake suggested an equation to estimate the number of extraterrestrial civilizations, now known as Drake equation. SETI Institute is searching for signals from intelligent space creatures. And METI foundation is trying to figure out the best ways to message them.
One of the first attempts to message extraterrestrials was the Golden Record sent onboard NASA Voyager space probes in 1977. The images and recordings for the Golden Record were selected by the committee chaired by Carl Sagan. However, looking back we realize that those selections may not be the optimal way to represent humanity and Earth. The images are very human-centered, not representative of our planet and its biosphere. Lots of modern technology is lacking. It is also not realistic to expect the extraterrestrials to process light, sound, and smell the same way we do. So, what is the most important to us? Who are “we”? How do we expect to change in the future? And what would be the best way to craft the next message to the extraterrestrials?
