==Age of the Milky Way==

With the use of space-based observations of the [[Cosmic microwave background| microwave background radiation]], scientists estimate that the first stars were formed some 200 million years after the [[Big Bang]], and that the Milky Way were among one of the first galaxies in the early universe with an estimated age of 13.6 billion ±800 million years.  This estimate was calculated by measuring the amount of [[beryllium]] in two stars within the cluster NGC 6397.<ref>http://arxiv.org/abs/astro-ph/0411699</ref> The two stars were found to be 13.4 billion years old.  Using the estimated time it took for earlier stars to form and exploded, adding Beryllium to the interstellar medium, allowing for the type of stars found in NGC 6397 to form, approximately some 200 million years, they calculated the 13.6 billion year age for the galaxy.<ref>http://www.universetoday.com/2004/08/22/estimating-the-age-of-the-milky-way/</ref>.  Although [[Creation science|creationist scientists]] disagree and highlight the many problems with this model<ref>http://www.pathlights.com/ce_encyclopedia/Encyclopedia/03-ss5.htm</ref>, these figures are accepted by the scientific community.

Old-earth creationists and atheists believe the first stars were formed some 200 million years after the [[Big Bang]], and that the Milky Way was among the first galaxies in the early universe.  They believe it is 13.6 billion years old, within 800 million years.  This estimate was calculated by measuring the amount of [[beryllium]] in two stars within the cluster NGC 6397,<ref>http://arxiv.org/abs/astro-ph/0411699</ref> which under their assumptions gave an age of 13.4 billion years.  They then added 200 million years to this estimate for their belief that beryllium takes this long to form.<ref>http://www.universetoday.com/2004/08/22/estimating-the-age-of-the-milky-way/</ref>.   

 

[[Creation science|Many other scientists]] disagree and highlight the many problems with this model<ref>http://www.pathlights.com/ce_encyclopedia/Encyclopedia/03-ss5.htm</ref>.  Debate continues on this topic in scientific communities.
