Over the past year and a half, data and images from the James Webb Space Telescope, or JWST, have been flooding in. And floating around in that sea of data (and from other instruments over the past 20 years) are at least three big problems: There appear to be too many big, bright galaxies, too soon after the Big Bang. No one can agree on how fast the universe is (or was) expanding. And we don’t know what most of the universe is made of.

The University of Texas at Austin brought together a panel of astronomy and physics faculty members to debate and discuss the meaning of these emerging problems in the data. The panelists were Kim Boddy, Mike Boylan-Kolchin, Karl Gebhardt, Can Kilic and Julian Muñoz. Have a listen and then decide: is cosmology really in crisis?

For a deeper dive into some of the issues raised in this episode, head over to this recently released video from the American Museum of Natural History’s Isaac Asimov Panel Debate, titled: “JWST’s Cosmic Revolution.” It features Mike Boylan-Kolchin, UT alum Neil DeGrasse Tyson and others.

Did the James Webb telescope ‘break the universe’? Maybe not

Cover image: JWST’s image of spiral galaxy NGC 628, which is 32 million light-years away in the constellation Pisces. The spiraling filamentary structure looks somewhat like a cross section of a nautilus shell. Read more.
