How to detect life on Mars

Posted by in category: alien life

“If there’s life on Mars, there’s a good chance it’s related to us.”


Scientists from SETG have developed a method to detect the tiniest traces of life on other planetary bodies.

Scientists looking for aliens investigate radio beam ‘from nearby star’

Posted by in category: alien life

Astronomers behind the most extensive search yet for alien life are investigating an intriguing radio wave emission that appears to have come from the direction of Proxima Centauri, the nearest star to the sun.

The narrow beam of radio waves was picked up during 30 hours of observations by the Parkes telescope in Australia in April and May last year, the Guardian understands. Analysis of the beam has been under way for some time and scientists have yet to identify a terrestrial culprit such as ground-based equipment or a passing satellite.

Extraterrestrial Languages

Posted by in categories: alien life, robotics/AI

If we send a message into space, will extraterrestrial beings receive it? Will they understand?

The endlessly fascinating question of whether we are alone in the universe has always been accompanied by another, more complicated one: if there is extraterrestrial life, how would we communicate with it? In this book, Daniel Oberhaus leads readers on a quest for extraterrestrial communication. Exploring Earthlings’ various attempts to reach out to non-Earthlings over the centuries, he poses some not entirely answerable questions: If we send a message into space, will extraterrestrial beings receive it? Will they understand? What languages will they (and we) speak? Is there not only a universal grammar (as Noam Chomsky has posited), but also a grammar of the universe?

Oberhaus describes, among other things, a late-nineteenth-century idea to communicate with Martians via Morse code and mirrors; the emergence in the twentieth century of SETI (the search for extraterrestrial intelligence), CETI (communication with extraterrestrial intelligence), and finally METI (messaging extraterrestrial intelligence); the one-way space voyage of Ella, an artificial intelligence agent that can play cards, tell fortunes, and recite poetry; and the launching of a theremin concert for aliens. He considers media used in attempts at extraterrestrial communication, from microwave systems to plaques on spacecrafts to formal logic, and discusses attempts to formulate a language for our message, including the Astraglossa and two generations of Lincos (lingua cosmica).

A NASA Scientist Heralds “One of the Most Profound Discoveries” of the Space Age

Posted by in category: alien life

In recent years, scientists have learned that one of Earth’s most unique features — its liquid oceans — is far more common throughout the solar system than scientists ever expected.

Take Ceres, a dwarf planet orbiting our Sun inside the asteroid belt, which scientists discovered earlier this year is actually an ocean world, according to Discover Magazine. The discovery of abundant water on other worlds could have huge implications for the search for extraterrestrial life — to the point that NASA astronomer Alan Stern tells Discover that it’s “one of the most profound discoveries in planetary science in the Space Age.”
