A new ESA telescope could help us understand how dark matter and dark energy influence the structure of the universe. Also, using both JWST and the Chandra Observatory, astronomers discover the oldest known black hole.<h2>Euclid Telescope’s First Images Unveiled</h2>This week, the European Space Agency unveiled the Euclid space telescope’s <a href="https://www.sciencefriday.com/segments/euclid-telescope-first-images/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">first full-color images of the cosmos.</a> The telescope has a wide field of view and is designed to take images of large swaths of the sky in both visible and infrared light. The telescope’s designers hope that they will be able to create a detailed 3D map of the cosmos over the next six years and, with that map, begin to sort out the influences of <a href="https://www.sciencefriday.com/segments/euclid-telescope-first-images/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">dark matter and dark energy</a> on the basic structure of the universe.Sophie Bushwick, technology editor at Scientific American, joins Ira to talk about the first images from the Euclid telescope and other stories from the week in science. They’ll try to explain the recent conversation about <a href="https://www.sciencefriday.com/segments/euclid-telescope-first-images/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">ultraprocessed foods</a> and discuss steps toward regulating AI coming from the Biden administration and a host of other countries; a move to rename some North American birds; and the tale of a fish that uses <a href="https://www.sciencefriday.com/segments/euclid-telescope-first-images/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">electrolocation and some shimmies</a> to get a 3D map of its environment.<h2>Not Just Dying Stars: A Black Hole That Came From Gas</h2>This week, astronomers confirmed that they had found the <a href="https://www.sciencefriday.com/segments/black-hole-discovery/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">oldest known black hole,</a> thanks to the James Webb Space Telescope (JWST) and the Chandra X-ray Observatory. The supermassive black hole formed when the universe was still a toddler, just 470 million years after the Big Bang. But its age isn’t the only thing that makes it unusual.Astronomers long thought that the only way a black hole could form was through the collapse of a star. But this week’s discovery confirms a theory that some black holes at this early stage in the universe formed from the <a href="https://www.sciencefriday.com/segments/black-hole-discovery/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">condensation of clouds of gas.</a> The theory purports that such black holes would produce superheated x-ray-emitting gas. Now, data from JWST and Chandra have helped confirm these x-ray signals from the newly discovered black hole. The findings are available via preprint and have been published in the journal Nature Astronomy.Ira sits down with Dr. Priyamvada Natarajan, a professor of astronomy and physics at Yale who helped develop this theory, to talk about how these unique black holes change our understanding of the early universe.To stay updated on all things science, <a href="https://www.sciencefriday.com/newsletters/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri">sign up for Science Friday's newsletters</a>.
