Astronomers discover Earth’s new ‘next-door neighbor’ — a potentially habitable planet
New York Post • • science
Key Points:
- Scientists have discovered a potentially habitable exoplanet named GJ 3378b, located about 25 light years from Earth, which is considered one of our closest cosmic neighbors.
- GJ 3378b is roughly twice the size of Earth and lies within the Goldilocks zone, where conditions may allow liquid water to exist on its surface.
- The planet's ability to support life depends on whether it has an atmosphere, as it sits on the edge of the "cosmic shoreline," balancing gravity against radiation exposure.
- Further observations are needed to confirm the presence of an atmosphere, which would enable searches for biosignatures and other signs of life.
- NASA's upcoming Habitable Worlds Observatory, expected to launch within the next two decades, aims to analyze exoplanet atmospheres for potential life-related chemicals.
