NOIRLab - Resolving A Discrepancy In The Hubble Constant

<p class="p1">The Hubble Constant tells us how fast the universe is expanding. However, different methods of measuring the Hubble Constant give different results. In this podcast, NOIRLab’s John Blakeslee describes data his team has collected to help resolve this discrepancy.<span class= "Apple-converted-space"> </span></p> <p class="p1"><strong>Bio:</strong> Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab.</p> <p class="p1">John Blakeslee is an Astronomer at NSF’s NOIRLab studying galaxies, galaxy clusters, and the expansion of the universe. He completed his PhD at MIT, followed by a postdoctoral fellowship at the CalTech. Dr Blakeslee has worked as a Research Scientist with the Hubble Space Telescope’s Advanced Camera project at Johns Hopkins University, a faculty member at Washington State University, a Staff Astronomer with the Canadian National Research Council in Victoria, British Columbia, and the Chief Scientist of Gemini Observatory. In addition to doing research, he now serves as the Head of Science Staff for Observatory Support at NOIRLab.</p> <p class="p2"> </p> <p class="p1"><strong>Links:</strong></p> <p class="p1"><a href= "https://noirlab.edu/public/news/noirlab2123/">https://noirlab.edu/public/news/noirlab2123/</a></p> <p class="p1"><a href= "https://noirlab.edu/public/blog/hubble-constant-result/">https://noirlab.edu/public/blog/hubble-constant-result/</a></p> <p class="p1">NOIRLab social media channels can be found at:</p> <p class="p1"><a href= "https://www.facebook.com/NOIRLabAstro">https://www.facebook.com/NOIRLabAstro</a></p> <p class="p1"><a href= "https://twitter.com/NOIRLabAstro">https://twitter.com/NOIRLabAstro</a></p> <p class="p1"><a href= "https://www.instagram.com/noirlabastro/">https://www.instagram.com/noirlabastro/</a></p> <p class="p1"><a href= "https://www.youtube.com/noirlabastro">https://www.youtube.com/noirlabastro</a></p> <p class="p2"> </p> <p class="p1">We've added a new way to donate to 365 Days of Astronomy to support editing, hostin
