Summary:
- The article discusses the discovery of a new exoplanet, named TOI-2257 b, located approximately 150 light-years from Earth.
- The exoplanet is a super-Earth, meaning it is larger than Earth but smaller than Neptune, and it orbits its host star in just 2.7 days.
- Observations of the exoplanet's atmosphere suggest it may have a substantial atmosphere, potentially composed of hydrogen and helium, which is unusual for a super-Earth.
