Astronomers have discovered a new category of exoplanets dubbed “Super Venus,” which appear to have no equivalent in our solar system. The “Super Venus” planets are located between Earth and Neptune, displaying properties that combine characteristics of gas giants, icy worlds, and rocky worlds.
Researchers from the University of Arizona and Japan analyzed data captured by the James Webb Space Telescope (JWST) on an exoplanet called GJ 1214 b. They found concentrations of carbon dioxide in its upper atmosphere similar to those of Earth’s neighbor, Venus. Using complex computer simulations and planetary formation models, they determined that this unique atmospheric signature points towards a rocky planet with a dense, carbon-dominated atmosphere.
The discovery is significant as it could aid scientists studying planetary formation and searching for exoplanets capable of supporting life. However, the researchers acknowledge that future research is required to confirm their findings. The team’s work suggests that these “Super Venus” planets may hold secrets about the complex dynamics behind planet formation in our galaxy.
These breakthroughs shed new light on the vast expanse of exoplanet discoveries, with over 5,000 worlds discovered so far. As scientists continue to explore the cosmos for potential life-bearing planets, this discovery could be a crucial step forward.
