Astronomers have identified an Earth-size planet candidate, HD 137010 b, orbiting a nearby star every 355 days — a rare detection with an Earth-like year. Its size and orbit make it one of the most promising targets so far for searching for signs of habitability and life. The discovery of L 98-59 d, with its molten surface and sulfur-rich atmosphere, underscores why direct atmospheric and surface measurements are essential: planets with similar sizes or orbits can have very different conditions, so follow-up observations are needed to assess true habitability.
