This artist's illustration shows what Mars might look like if it were terraformed. New research shows how the effects of terraforming, whether intentional or not, could help identify clusters of planets the are habitable and that life has spread to. Image Credit: Daein Ballard / CC BY-SA 3.0.

Researchers Propose a New Way to Search for Alien Life by Looking at Groups of Planets

A new astrobiology paper argues that life may be easier to detect across patterns in groups of planets than through ambiguous biosignatures on any single world.

Key Takeaways

A new paper proposes looking for life through patterns across groups of planets rather than only single-world biosignatures.
The model explores how panspermia or terraforming could create observable planetary population signatures.

New Chemical Signatures Could Detect Truly Alien Life

Scientists propose new chemistry-based methods to identify extraterrestrial life that may be fundamentally different from any organism found on Earth.
