Kepler 22b is considered a candidate for harboring life due to its location in the habitable zone of its parent star, but definitive evidence is lacking. Researchers suggest that detecting chemical signatures in its atmosphere could provide insights into the possibility of life, although the necessary technology is still under development. Current spacecraft would require tens of millions of years to reach Kepler 22b, making direct exploration impractical for the foreseeable future. A Hoffmann transfer to this exoplanet raises questions about delta v requirements, but the focus remains on atmospheric analysis rather than travel. Overall, while Kepler 22b presents intriguing possibilities, confirming life there remains a distant goal.
