In a recent investigation published by the Journal NatureScientists have discovered a Dense atmosphere wrapped up Super Earth “55 Cangri E”, which has twice the dimensions of our planet. Located 41 light-years away in the nearest solar system, this exoplanet stands out not only for its size but also for the extreme temperatures it reaches, which can reach up to 2,200 degrees Celsius (4,200 degrees Fahrenheit). Magma oceans on their surface.
This discovery is significant because “55 Cancri e” is one of the few rocky planets outside our planet. Identified the Solar System with a significant atmosphereMainly composed Carbon Dioxide and Monoxide, the exact proportions of these gases are still unclear. The presence of this atmosphere suggests the possibility of other rocky planets with similar atmospheric characteristics, but with conditions more favorable for life. “It probably is Even stronger evidence “This planet has an atmosphere,” said Ian Crossfield, an astronomer at the University of Kansas who was not involved in the study.
The study highlighted how Web Space Telescope It played a key role in separating the light emitted by the planet from that of its star, allowing scientists to identify the composition of the atmosphere. This process revealed how the planet's heat is evenly distributed across its surface, which is usually associated with the presence of an atmosphere. The Gases from magma oceans “55 Cancri e” plays an important role in maintaining the stability of this atmosphere. “We can probe this early stage of the planet's evolution,” said Renyu Hu, a planetary scientist at NASA's Jet Propulsion Laboratory and part of the research team.
Scientists point out that Very high temperature And this Proximity of the planet to its star As a result of Copernicus having perpetually facing sides of light and dark, “55 Cancri e” reduces the chances of supporting life as we know it. However, the real value of this discovery lies in its contribution to our understanding of atmospheric processes on distant rocky planets and their evolution over time.
curiosity Super Earths That's being boosted by other recent discoveries, including two planets orbiting a red dwarf star 100 light-years away in 2022. One of these planets, called “LP 890-9c,” may even be habitable. Additionally, in August 2022, NASA scientists identified another super-Earth, they suggest “Water World”, capable of sustaining life. It is expected that The James Webb Space Telescope Provide detailed information about this planet in future. “As soon as we can, we will devote time to the web to observe this strange and wonderful world,” says researcher René Doyen, who looks forward to further studies.
The study of “55 Cancri e” and other similar celestial bodies not only expands our knowledge of the universe, but also provides clues as to how more familiar bodies such as Earth and Mars may have begun to evolve with later cooled magma oceans. This highlights the importance of this type of research Advanced technology In search of answers to fundamental questions about space exploration and the possibility of life on other planets.
