‘Highly Plausible’ Aliens on Europa Are Earthlings’ Descendants, Study Says

Could Europa Already Host Earth Life? A Study Revives a Panspermia Question

A new study argues that bacteria launched from Earth on dust grains could plausibly reach Europa and, in rare cases, survive long enough to matter.

Key Takeaways

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.

Study explores whether Venus cloud life, if real, could have arrived from Earth

A study presented at the 2026 Lunar and Planetary Science Conference examines whether organic material ejected from Earth could seed temporary life in Venus’ clouds.

Key Takeaways

A study at LPSC 2026 explored whether Earth ejecta could seed Venus’ clouds.
The models suggest life could persist there for a few days per century.
