Life in the Universe Solar System Discussion
Answer questions for Discussion Question 2: Life in the Universe Solar System Discussion
Discussion Question 2: Stellar nurseries are massive regions of star formation much like the region in which our own star formed. Once these baby stars form they eventually get gravitationally ejected from the region and move into interstellar space. Stars are formed in bundles in this regard and our Sun likely has numerous brothers and sisters that formed from the same cloud as ours. They are out there independently revolving around the center of the Milky Way as we are. Our Sun’s sister may be on the other side of galaxy. So we can see that these large star forming regions are star factories using the remnants of past dead stars to form new ones and possibly new life. We can also see the formation of stars occurring in these areas at all different stages and use these observations to test our theories. Do you imagine that we can see solar systems in these regions as well? Given the numbers of stars we see in the Universe what conclusion could you make about the likelihood of life on one of these planets? Defend your opinion.
