Scientists have discovered a thick atmosphere around a super Earth known as 55 Cancri e, which is twice the size of Earth and located in a nearby solar system. This rocky planet has an atmosphere consisting of carbon dioxide and carbon monoxide, although the exact amounts are uncertain. Unlike Earth’s nitrogen-oxygen blend atmosphere, 55 Cancri e’s atmosphere is unique in its composition.
The detection of this atmosphere on the super Earth is considered strong evidence for its existence. Research published in the journal Nature provides insights into the planet’s atmosphere and its potential implications for other rocky planets with thick atmospheres that could potentially be more hospitable to life. However, despite its size, this super Earth is unlikely to host life due to its boiling temperatures reaching up to 4,200 degrees Fahrenheit.
Instead of focusing on this super Earth’s uninhabitable conditions, scientists are intrigued by studying other similar rocky planets that may have atmospheres conducive to life. One such exoplanet, located 41 light years away and significantly heavier than Earth, presents a unique opportunity for researchers to explore its atmosphere and surface conditions. By analyzing observations from the Webb Space Telescope before and after the planet passed behind its star, researchers were able to determine the planet’s temperature and study the distribution of heat across its surface. This exploration could provide insights into the early evolution of planets like Earth and Mars, offering a rare window into the past.
Overall, while 55 Cancri e may not be hospitable to life due to its extreme temperatures, it still offers valuable information that could shape our understanding of planetary evolution and provide clues about the potential habitability of other rocky planets in our galaxy.
