I found this article to be very interesting it ties very well into what we have been learning about with the universe. The article talks about how astronomers have used old stars to determine the age of the universe. The article tells how Timothy Beers and his associates have discovered a radioactive isotope, uranium-238, in a metal-poor star located on the outskirts of the milkyway.
I suppose I should give a little back that the article talked about first. Astronomers have found the age of many stars by using radioactive dating. See astronomers are able to calculate the age of a star by using this radioactive dating.
This method does work for older stars that were formed from just hydrogen, helium and lithium these are nonradioactive elements that are called metal poor-stars. Well it is believe that some of these stars were massive and exploded and set off nuclear reactions that made a second generation of metal-poor stars and some of these stars contained radioactive isotopes.......
