Extraterrestrial life may look nothing like life on Earth—astrobiologists seek framework for how complex systems evolve
We have only one example of biology forming in the universe—life on Earth. But what if life can form in other ways? How do you look for alien life when you don't know what alien life might look like?

A technosignature that could detect an extraterrestrial civilization's reliance on nuclear fusion
Extraterrestrial civilizations need a great deal of energy as they advance up the Kardashev scale. Fossil fuels are finite, wind and solar energy are carbon free but not as efficient as fossil fuels, and traditional nuclear ...
'We live in a universe that is just right for us': Study proposes a test for the Anthropic Principle
The Anthropic Principle—stating that the universe we live in is fine-tuned to host life—was first proposed by Brandon Carter in 1973. Since then, it has sparked significant debate.
