On which potentially habitable super-Earth has the presence of water vapor been detected?
Show answer Hide answer
Answer: D. K2-18b
Explanation
Researchers utilizing the Hubble Space Telescope detected atmospheric water vapor on a distant exoplanet. K2-18b was identified as a potentially habitable super-Earth located many light-years away from our solar system. Spectroscopic analysis of starlight passing through the planet's atmosphere revealed the presence of moisture. Exoplanets are planets that orbit stars outside our solar system, discovered through advanced astronomical instruments. Super-Earths are exoplanets with masses larger than Earth but substantially smaller than ice giants. The habitable zone refers to the orbital region around a star where liquid water could theoretically exist.
Discovering water vapor on distant planets is a major milestone in the scientific search for potential extraterrestrial life. Advanced space telescopes allow astronomers to characterize the chemical composition of alien planetary atmospheres. Astrobiology research expands our understanding of planetary formation and the conditions necessary for life. K2-14d, K2-15c, and K2-13a are different celestial bodies not associated with this specific water vapor detection. K2-18b is the correct exoplanet studied by researchers using space-based telescopes. Selecting alternative designation codes contradicts published astronomical research findings.
