John Batchelor and I welcomed Dr. Mark Brodwin to discuss the discovery and measurement of the massive young galaxy cluster IDCS 1426.  Dr. Brodwin discussed the detailed analysis since 2012 by multiple ground and space telescopes.  He told us how galaxy cluster mass is measured, plus he extrapolated the 10 billion light years away to what it would be like today in real time.  We also talked about the size of this galaxy cluster being about equal to 500 trillion Earth suns!  John and I asked Mark technical questions about the contributions of the different ground and space based telescopes, plus our guest helped us to understand the science associated with this discovery.  Stay tuned for more as Dr. Brodwin will be a full Space Show program guest next month.

You can email Mr. Batchelor or Dr. Brodwin through me at drspace@thespaceshow.com or through Dr. Brodwin's university website at the University of Missouri, Kansas City.
