New study suggests intelligent life is rare for the Milky Way – and if another civilization exists, it is much older than us
In a new study, researchers from Penn State University and NASA's Jet Propulsion Laboratory analyzed human communications in deep space and found that human transmissions are often directed toward our spacecraft near Mars (bottom left), the Sun, and other planets. Because planets like Mars don't completely block the signal, an extraterrestrial intelligence that happens to be along the path of interplanetary communications—when the stars are aligned from its perspective—could detect the "leak." This finding suggests that humans should look for planetary alignments outside the solar system when searching for signs of extraterrestrial communications. Credit: Zaina Sheikh

If aliens are looking for us – this is how they will find us

  • One response
The study indicates that if an alien civilization is trying to detect signals from Earth, the highest chance is during an alignment between Earth and Mars, when transmissions are made to spacecraft and rovers on Mars.
