To access these X-ray tracks, or observations, the ultimate compendium has been developed: the Chandra Source Catalog (CSC). https://chandra.harvard.edu/resources/podcasts/media/pod060126.mp3 /resources/podcasts/ts/ts060126_hd.html Tue, 06 Jan 2026 12:00:00 EST A new video shows the evolution of Kepler's Supernova Remnant using data from NASA's Chandra X-ray Observatory captured over more than two and a half decades. https://chandra.harvard.edu/resources/podcasts/media/pod301225.mp3 /resources/podcasts/ts/ts301225_hd.html Tue, 30 Dec 2025 12:00:00 EST Celebrate the New Year with the "Champagne Cluster," a galaxy cluster seen in this new image from NASA's Chandra X-ray Observatory and optical telescopes. https://chandra.harvard.edu/resources/podcasts/media/pod221225.mp3 /resources/podcasts/ts/ts221225_hd.html Mon, 22 Dec 2025 12:00:00 EST NASA's Chandra X-ray Observatory is sending out a holiday card with four new images of cosmic wonders. Each of the quartet of objects evokes the winter season or one of its celebratory days either in its name or shape. https://chandra.harvard.edu/resources/podcasts/media/pod091225.mp3 /resources/podcasts/ts/ts091225_hd.html Tue, 09 Dec 2025 12:00:00 EST A new image-processing technique called "X-arithmetic" is allowing astronomers to analyze Chandra's X-ray data and identify features in the gas of galaxy clusters and groups like never before. https://chandra.harvard.edu/resources/podcasts/media/pod241125.mp3 /resources/podcasts/ts/ts241125_hd.html Mon, 24 Nov 2025 12:00:00 EST Before fall gives way to winter in the northern hemisphere, NASA's Chandra X-ray Observatory has several images that celebrate autumn and its many delights to share. https://chandra.harvard.edu/resources/podcasts/media/pod180925.mp3 /resources/podcasts/ts/ts180925_hd.html Thu, 18 Sep 2025 12:00:00 EST A black hole is growing at one of the fastest rates ever recorded. This discovery from NASA's Chandra X-ray Observatory may help explain how some black holes can reach enormous masses relatively quickly after the Big Bang. https://chandra.harvard.edu/resources/podcasts/media/pod280825.mp3 /resources/podcasts/ts/ts280825_hd.html Thu, 28 Aug 2025 12:00:00 EST The star that exploded to become the Cassiopeia A supernova remnant appears to have undergone a dramatic event right before its demise. New evidence from Chandra indicates that the star's interior was violently rearranged just hours before the explosion. https://chandra.harvard.edu/resources/podcasts/media/pod200825.mp3 /resources/podcasts/ts/ts200825_hd.html Wed, 20 Aug 2025 12:00:00 EST In 2009, Chandra released a captivating image: a pulsar and its surrounding nebula that is shaped like a hand. Since then, astronomers have used Chandra and other telescopes to continue to observe this object. https://chandra.harvard.edu/resources/podcasts/media/pod160725.mp3 /resources/podcasts/ts/ts160725_hd.html Wed, 16 Jul 2025 12:00:00 EST A baby planet is shrinking from the size of Jupiter with a thick atmosphere to a small, barren world, according to a new study from NASA's Chandra X-ray Observatory. https://chandra.harvard.edu/resources/podcasts/media/pod250625.mp3 /resources/podcasts/ts/ts250625_hd.html Wed, 25 Jun 2025 12:00:00 EST Astronomers study Andromeda to better understand the structure and evolution of our own spiral galaxy, the Milky Way. https://chandra.harvard.edu/resources/podcasts/media/pod090625.mp3 /resources/podcasts/ts/ts090625_hd.html Mon, 09 Jun 2025 12:00:00 EST A black hole has blasted out a surprisingly powerful jet in the distant universe. This jet exists early enough in the cosmos that it is being illuminated by the leftover glow from the big bang itself. https://chandra.harvard.edu/resources/podcasts/media/pod040625.mp3 /resources/podcasts/ts/ts040625_hd.html Wed, 04 Jun 2025 12:00:00 EST New observations have captured a powerful cosmic event: two galaxy clusters have collided and are now poised to head back for another swipe at each other. https://chandra.harvard.edu/resources/podcasts/media/pod280525.mp3 /resources/podcasts/ts/ts280525_hd.html Wed, 28 May 2025 12:00:00 EST Scientists have discovered a star behaving like no other seen before, giving new clues about the origin of a class of mysterious objects. https://chandra.harvard.edu/resources/podcasts/media/pod090525.mp3 /resources/podcasts/ts/ts090525_hd.html Fri, 09 May 2025 12:00:00 EST This new trio of sonifications represents different aspects of black holes. https://chandra.harvard.edu/resources/podcasts/media/pod080525.mp3 /resources/podcasts/ts/ts080525_hd.html Thu, 08 May 2025 12:00:00 EST Astronomers have discovered a black hole has torn apart a star in a surprising location. https://chandra.harvard.edu/resources/podcasts/media/pod010525.mp3 /resources/podcasts/ts/ts010525_hd.html Thu, 01 May 2025 12:00:00 EST Astronomers have discovered a likely explanation for a fracture in a huge cosmic "bone" in the Milky Way galaxy, using NASA's Chandra X-ray Observatory and radio telescopes. https://chandra.harvard.edu/resources/podcasts/media/pod160425.mp3 /resources/podcasts/ts/ts160425_hd.html Wed, 16 Apr 2025 12:00:00 EST New three-dimensional (3D) models of objects in space have been released by NASA's Chandra X-ray Observatory. These 3D models allow people to explore – and print – examples of stars in the early and end stages of their lives. https://chandra.harvard.edu/resources/podcasts/media/pod270325.mp3 /resources/podcasts/ts/ts270325_hd.html Thu, 27 Mar 2025 12:00:00 EST People often think about archaeology happening deep in jungles or inside ancient pyramids. However, a team of astronomers has shown that they can use stars and the remains they leave behind to conduct a special kind of archaeology in space. https://chandra.harvard.edu/resources/podcasts/media/pod040325.mp3 /resources/podcasts/ts/ts040325_hd.html Tue, 04 Mar 2025 12:00:00 EST After tracking a puzzling X-ray signal from a dying star for decades, astronomers may have finally explained its source: the old star might have destroyed a nearby planet. https://chandra.harvard.edu/resources/podcasts/media/pod120225.mp3 /resources/podcasts/ts/ts120225_hd.html Wed, 12 Feb 2025 12:00:00 EST A bouquet of thousands of stars in bloom has arrived. This composite image contains the deepest X-ray image ever made of the spectacular star forming region called 30 Doradus.
