New Study Suggests Earth and Many Exoplanets Are Less Unique Than Previously Thought
New research indicates that planets outside our solar system, including the exoplanet K2-18b, contain far less surface water than previously believed, challenging earlier theories of water-rich worlds and suggesting Earth may be more typical than extraordinary. The study highlights the importance of chemical interactions between planetary atmospheres and interiors in determining water content, which has implications for the search for extraterrestrial life.
