科學家於開普勒69c發現外星生命
普勒69c和地球的比較
環繞與太陽類似的恆星開普勒69c，軌道位置在該恆星的適居帶，科學家發現普勒69c中大部分面積(68%)為液態水。

A Potential Super-Venus in the Kepler-69 System
http://arxiv.org/abs/1305.2933
Here we examine one such proposed planet, Kepler-69c. We provide new orbital parameters for this planet and an in-depth analysis of the Habitable Zone. We find that, even under optimistic conditions, this 1.7 R$_\oplus$ planet is unlikely to be within the Habitable Zone of Kepler-69. Furthermore, the planet receives an incident flux of 1.91 times the solar constant, which is similar to that received by Venus. We thus suggest that this planet is likely a super-Venus rather than a super-Earth in terms of atmospheric properties and habitability, and we propose follow-up observations to disentangle the ambiguity.
