Host Dave Schlom sets his sites on some cosmic mysteries -- the physics of black holes and the latest discovery of a cluster of galaxies closer to the birth of the universe than any yet detected.

We learn about the bizarre nature of black holes from NASA Jet Propulsion Lab astrophysicist Varoujan Gorjian who explains what we know about these objects in a fascinating conversation.

Then, we find out about a discovery that made lots of news earlier this year, the discovery of the youngest cluster of galaxies yet found by the James Webb Space Telescope. Should there even be a cluster of galaxies a mere 650 million years after the Big Bang.

Dave finds out from Caltech astronomer Takahiro Morishita, lead author of the paper that appeared in the journal Astrophysical Journal Letters.

Dave Schlom is the longtime host and creator of Blue Dot. From surfing to Voyager in interstellar space, rock guitar to orcas in our imperiled oceans, the topics on Blue Dot are as varied as the host’s interests and connections -- which are pretty limitless! An internationally respected space history journalist, Dave is also deeply fascinated by all aspects of the grand workings of nature’s awesome machinery on scales ranging from galactic to subatomic. And topics take in all aspects of the arts and sciences.
