Astronomers Discover Enaiposha: A ‘Super-Venus’ Exoplanet Redefining Planetary Classifications
In a groundbreaking discovery, astronomers have identified a new type of exoplanet, Enaiposha, also known as GJ 1214 b, located approximately 47 light-years from Earth. This celestial body, initially classified as a planet similar to a mini-Neptune, has now been redefined as a ‘Super-Venus’ thanks to advanced observations from the James Webb Space Telescope (JWST).
Enaiposha orbits a red dwarf star and has a radius 2.7 times that of Earth and a mass 8.2 times greater. Its thick, hazy atmosphere, rich in metals, challenges existing exoplanet classifications and reshapes our understanding of extreme planetary environments.

Initially, Enaiposha was thought to resemble a mini-Neptune, a common type of exoplanet with a dense atmosphere of hydrogen and helium. However, JWST’s detailed observations revealed that its atmospheric composition and structure are more akin to Venus, albeit substantially larger. This discovery has led astronomers to coin the term ‘Super-Venus’ to describe this unique category of exoplanets.
Why Enaiposha Matters
Enaiposha is one of the most studied exoplanets in the sky,first discovered in 2009. Its proximity to Earth makes it an ideal candidate for detailed observation, providing valuable insights into planetary formation and atmospheric dynamics.
While Enaiposha is too close to its parent star to support life, its study could help scientists understand the conditions necessary for habitability on other exoplanets. As quoted from Science Alert, “This planet can provide information that might help us understand the diversity of planetary systems in our galaxy.”
Exoplanet Categories: A Fast Comparison
To better understand Enaiposha’s significance, here’s a comparison of the key exoplanet categories:
| Category | Characteristics | Example |
|———————|————————————————————————————-|———————-|
| Super-Earth | Terrestrial exoplanets larger than Earth, with a hydrogen-rich atmosphere. | Kepler-452b |
| Mini-Neptune | Similar in size to Super-Earths but with a dense atmosphere of hydrogen and helium. | GJ 1214 b (initially)|
| Super-Venus | Larger than Venus, with a thick, hazy, metal-rich atmosphere. | Enaiposha (GJ 1214 b)|
The Future of Exoplanet Studies
The discovery of Enaiposha underscores the importance of advanced telescopes like JWST in uncovering the mysteries of the cosmos. As astronomers continue to explore the universe, findings like this will redefine our understanding of planetary classifications and the potential for life beyond our solar system.

Astronomers Discover Carbon Dioxide in the Atmosphere of Exoplanet Enaiposha, Hinting at a “Super-venus”
In a groundbreaking discovery, astronomers have detected carbon dioxide (CO₂) in the atmosphere of the exoplanet Enaiposha, also known as GJ 1214 b. This finding, published in two papers in The Astrophysical Journal Letters, suggests that the distant world could be a “Super-Venus”—a scorching, metal-rich planet with a dense, carbon-heavy atmosphere.
A Thick Atmosphere Hiding Secrets
Enaiposha, located approximately 40 light-years from Earth, has long intrigued scientists due to its thick, opaque atmosphere, which makes it challenging to study. Previous observations using the James Webb Space Telescope (JWST) and Hubble Space Telescope hinted at a water-rich atmosphere with evaporating metals. Though, the latest research led by Everett Schlawin of the university of Arizona and Kazumasa Ohno of the National Astronomical Observatory of Japan has revealed something even more surprising.
By analyzing data from Enaiposha’s transit—when the planet crosses in front of its host star—the team detected a faint but notable CO₂ signal. “The CO₂ signal detected from the first small research is a careful statistical analysis to ensure that the signal is real,” Ohno explained. The concentration of CO₂ is comparable to that of Venus, where carbon dioxide makes up over 96% of the atmosphere.
A Metal-Rich World with a Hazy Atmosphere
To explain thes observations,the researchers developed theoretical models. The most plausible scenario suggests that Enaiposha’s lower atmosphere is dominated by metals, with only a small amount of hydrogen. At higher altitudes, the atmosphere is composed of dense fog and aerosols, along with the detected CO₂.
This unique composition has led scientists to classify Enaiposha as a Super-Venus—a planet similar to Venus but even more extreme. “The idea of a Super-Venus emerged, a world very hot and squeezed by a carbon-rich atmosphere, making it difficult to observe,” the researchers noted.
Challenges and Future Research
Despite these exciting findings, the complexity of Enaiposha’s atmosphere poses significant challenges. The observed CO₂ signature is extremely weak, requiring high-precision follow-up observations to confirm the team’s conclusions. “We emphasize the importance of follow-up observations with high precision to ensure the atmosphere is dominated by metals,” the researchers wrote.”This challenges conventional understanding of the interior structure and sub-Neptune evolution.”
The discovery of CO₂ in Enaiposha’s atmosphere not only sheds light on the planet’s composition but also raises questions about the diversity of exoplanetary atmospheres. As astronomers continue to study this enigmatic world,it could provide valuable insights into the formation and evolution of planets beyond our solar system.
