Thanks Ron,

Incredibly profound that they have been actually observed.

That's pretty cool, I wrote a review paper on the Population III stars a few years ago, fascinating stars! With this recent discovery it means that we may not NEED James Webb Telescope to be able to detect these heavily redshifted stars. We are still yet to detect one of their supernovae, given time we'll get there. Really looking forward to JWT though!

The era during & just after the Pop III star formation is little known outside of theory. This 2015 paper (http://adsabs.harvard.edu/abs/2015arXiv150202670T) by Michele Trenti sets these stars into a cosmological context by examining their role in some of the most familiar objects we view, globular clusters. Those starry speckles that entertertain our eyes would not be what they are today without the Pop III stars that first energized and seeded them. Copy Figure 2 on page 3, lay it next to your star charts, and see 13.5 billion years in the eyepiece and what happened in between on the piece of paper.

Hi Dana,

Thanks for the reference to the interesting paper (http://arxiv.org/pdf/1502.02670v1.pdf).
