Scientists narrow search for alien life to five planets

News » Science & Technology

Cassandra Hall, an astronomer at the University of Georgia, has created a new set of criteria to help find life on other planets, significantly reducing the scope of research.

Previously, astrobiologists have tried to find water on planets near stars. However, astronomers cannot analyze planetary resources in detail due to limited observation time and material resources.

Cassandra Hall insists that limited resources can be used more efficiently by prioritizing the analysis of planets that can support photosynthesis.

Hall's theory significantly narrows the search for a habitable or non-habitable planet. After all, photosynthesis requires an ideal temperature regime, water and a certain light intensity.

Hall's clarification means that red dwarf planets can be excluded from search, and resources can be better reallocated.

Five planets currently meet the new criteria: Kepler-452-b, Kepler-1638b, Kepler-1544b, Kepler-62e, and Kepler-62f.

Efforts to find a habitable planet are becoming increasingly urgent, not because of possible contact with aliens, but because of growing concern that the climate crisis will make our Earth unsustainable. fit for life.
