Planets:WaterFrom the equation that determines the average temperature of a planet, it is readily seen that even small changes in the distance, albedo and greenhouse effect of the planet, if not properly compensated, can elliminate liquid water from the surface of the planet either through run...
Any such planet situated in the right orbit stands a good chance of having liquid water on its surface, and quite possibly life, although a leading scientist involved in the project said it was unlikely to find "any little green men". 4. Developed by the French space agency, CNES, and...
Planet 'Earth' has the wrong name - it should be Planet 'Water'. The solar system and the universe is full of 'Earth' planets. Our 'Planet Water' is unique with liquid water covering 70% of its surface. 'Water is the Hub of life' and our lives and the future of life on our pla...

After spending years searching for a planet with life, scientists may have found one.In September 2010, a team of US scientists discovered an Earth-sized planet called Gliese 581 g.It has a surface temperature neither too hot nor too cold for liquid(液态)water.Scientists think there is a ch...

Student: Water? 学生:水? Professor: Yes, it need to be the right temperature to sustain liquid water. 教授:是的,它需要有适宜的温度以维持液态的水。 Student: And it would need to be a rocky planet, I mean, as opposed to a gas giant. ...
atmosphere. But Mars is the only place where we have solid evidence for liquid that sits right there in the open air. While it would be a major leap to suggest that Mars might harbor life—even microbial life—liquid water at least makes it possible that parts of the planet are habitable...
planet with a tenuous and toxic atmosphere. At theMars surface, pressure and temperature conditions are below the triple point of water, so water cannot exist in liquid form for extended periods of time. The atmosphere, consisting mainly of carbon dioxide, is highly oxidizing. Together with the...
