Key Takeaways:
– Gliese 667Cc is an extrasolar planet located within the habitable zone of its parent star.
– It is considered a “super-Earth” due to its higher mass compared to Earth.
– The planet receives slightly less light than Earth but in the form of infrared, which still provides a similar amount of energy.
– This discovery suggests that Earth-like planets and intelligent civilizations could be more common than previously thought.

The Discovery of Gliese 667Cc
Gliese 667Cc was discovered in 2011 by a team of astronomers using the High Accuracy Radial Velocity Planet Searcher (HARPS) instrument. The planet orbits the star Gliese 667C, which is part of a triple star system located approximately 22 light-years away from Earth. The discovery of Gliese 667Cc was significant because it was the first potentially habitable exoplanet found in a triple star system.
Characteristics of Gliese 667Cc
Gliese 667Cc has a mass approximately 4.5 times that of Earth and orbits its parent star with a period of about 28 days. It is located within the habitable zone, also known as the Goldilocks zone, where conditions are just right for liquid water to exist on the planet’s surface. The planet’s radius is estimated to be about 1.5 times that of Earth, making it a “super-Earth.”
The Habitability of Gliese 667Cc
The habitability of Gliese 667Cc depends on various factors, including its atmosphere, temperature, and the presence of water. While more research is needed to determine the exact conditions on the planet, its location within the habitable zone suggests that it could potentially support liquid water, a key ingredient for life as we know it.
Potential for Life on Gliese 667Cc
The potential for life on Gliese 667Cc is an intriguing possibility. The planet receives slightly less light than Earth, but the light it does receive is in the form of infrared radiation. Infrared radiation can still provide a similar amount of energy as visible light, which means that Gliese 667Cc could potentially have a similar energy source to Earth. This opens up the possibility of photosynthetic organisms and potentially even complex life forms.
Implications of the Discovery
The discovery of Gliese 667Cc has significant implications for our understanding of the universe and the prevalence of Earth-like planets. It suggests that habitable planets could be more common than previously thought, increasing the chances of finding extraterrestrial life. The fact that Gliese 667Cc is located in a triple star system also raises interesting questions about the stability of planetary systems and the potential for habitable environments in such systems.
Future Exploration and Research
Further exploration and research are needed to gather more information about Gliese 667Cc and its potential for hosting life. Scientists are developing new technologies and instruments that will allow us to study exoplanets in more detail, including their atmospheres and composition. The James Webb Space Telescope, set to launch in 2021, will play a crucial role in this endeavor by providing unprecedented insights into the atmospheres of exoplanets.
Conclusion
The discovery of Gliese 667Cc has opened up new possibilities in the search for habitable exoplanets and extraterrestrial life. Its location within the habitable zone and its potential for hosting liquid water make it an exciting target for future exploration and research. As our understanding of the universe continues to expand, discoveries like Gliese 667Cc remind us that we are not alone and that the potential for life beyond Earth is vast and intriguing.
