James Webb Space Telescope discovers a lemon-shaped exoplanet unlike anything seen before: 'What the heck is this?'
  • The James Webb Space Telescope (JWST) has made a surprising discovery of an exoplanet shaped like a lemon, which defies existing theories of planet formation due to its unusual characteristics and high temperatures. This finding has left scientists questioning the mechanisms behind its formation and composition.
  • This discovery is significant as it challenges current understandings of planetary science and formation processes. The unique shape and atmospheric composition of the exoplanet could lead to new insights into the diversity of planetary bodies in the universe.
  • The discovery of this lemon-shaped exoplanet adds to a growing list of remarkable findings by the JWST, including the identification of ancient supernovae and the observation of massive stars in the early universe. These developments highlight the telescope's role in expanding knowledge about cosmic phenomena and the evolution of celestial bodies.
