According to popular media, the search for alien life involves advanced technology, space exploration and sometimes even government conspiracies and secret programs. But according to University of ...

This video explores whether alien life would really need DNA, or whether that assumption is just a product of Earth’s own biology. By looking at RNA worlds, alternative genetic molecules like XNAs, ...

Historically, many scientists and society have been fascinated by the prospect of making contact with extraterrestrial civilisations. People around the world have wished for the day we discover an ...

When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, ...

Machine learning is quietly rewriting the rules of the cosmic hunt for company. Instead of waiting to recognize familiar fingerprints of biology, researchers are training algorithms to spot the deeper ...

This study marks the first detailed chemical analysis of freshly ejected plume grains. Scientists have found new evidence suggesting Saturn's icy moon Enceladus may harbour conditions suitable for ...

Two major alien-life announcements in 2025 generated enormous excitement, but most astrobiologists remained unconvinced. Only 6.6% of surveyed experts thought possible biological molecules on K2-18b ...

A new method to recognise the chemical properties of living things could help us detect alien life even if it functions differently from life on Earth. When searching for alien life, scientists ...

More than 86% of astrobiologists surveyed by Durham University in 2024 believe alien life likely exists somewhere in the universe right now, even as no confirmed evidence has yet been found. The ...
