Astronomy Test 3 Flashcards | Quizlet Which of the following would be true in that case?, Scientists think it is very unlikely that complex and large forms of life could evolve on planets that orbit stars that are much more massive than the Sun
Suppose that our Sun was cool enough to include Mercury in its . . . If the Sun was cool enough for Mercury to be in the habitable zone, it means that the sun's heat and light intensity would be much lower than it currently is In such a scenario, the most likely outcome would be: Only Mercury would be in the Sun's habitable zone
Habitable zone - Wikipedia At the outer edge light from the star is insufficient even with help from atmospheric gas and the planet's water freezes Liquid water is considered by many scientists as necessary but not sufficient for a habitable planet Many other factors are added in various habitable zone models
The Habitable Zone - Science@NASA Because our Sun has nurtured life on Earth for nearly 4 billion years, conventional wisdom would suggest that stars like it would be prime candidates in the search for other potentially habitable worlds
Chapter 19 Flashcards | Quizlet Which of the following would be true in that case?, Scientists think it is very unlikely that complex and large forms of life could evolve on planets that orbit stars that are much more massive than the Sun
Chapter 18 Astronomy Flashcards | Quizlet Which of the following would be true in that case?, Scientists think it is very unlikely that complex and large forms of life could evolve on planets that orbit stars that are much more massive than the Sun
Suppose that our sun was cool enough to include Mercury in its . . . In summary, if our Sun were cooler, Mercury could potentially support liquid water and possibly life if all conditions aligned appropriately An example that supports the idea of habitability is Earth, which sits in the Sun's habitable zone, where water exists in liquid form
