This finding may lead astronomers to adjust their understanding of our home galaxy's structure. https://chandra.harvard.edu/resources/podcasts/media/pod150626.mp3 /resources/podcasts/ts/ts150626_hd.html Mon, 15 Jun 2026 12:00:00 EST The aftermath of a stellar explosion should be a slowly fading cloud of hot gas. So when astronomers pointed NASA's Chandra X-ray Observatory at the nearby galaxy M83, the last thing they expected to find was a population of supernova remnants appearing to dramatically change in brightness. https://chandra.harvard.edu/resources/podcasts/media/pod110626.mp3 /resources/podcasts/ts/ts110626_hd.html Thu, 11 Jun 2026 12:00:00 EST Astronomers may have found a supernova remnant in an intriguing neighborhood in the middle of our galaxy. If confirmed, it would be one of the closest ever discovered to the supermassive black hole at the central region of the Milky Way galaxy. https://chandra.harvard.edu/resources/podcasts/media/pod120526.mp3 /resources/podcasts/ts/ts120526_hd.html Tue, 12 May 2026 12:00:00 EST New Chandra observations of "the most relaxed cluster in the Universe," Abell 2029, clearly show that it had a much more colorful history than its current disposition suggests. https://chandra.harvard.edu/resources/podcasts/media/pod280426.mp3 /resources/podcasts/ts/ts280426_hd.html Tue, 28 Apr 2026 12:00:00 EST This image of a special object, dubbed the "X-ray dot," represents a discovery from NASA's Chandra X-ray Observatory that could help explain the nature of a mysterious class of sources in the early Universe. https://chandra.harvard.edu/resources/podcasts/media/pod140426.mp3 /resources/podcasts/ts/ts140426_hd.html Tue, 14 Apr 2026 12:00:00 EST A new study from NASA's Chandra X-ray Observatory shows how young, Sun-like stars are calming down and dimming in their X-ray output more quickly than previously thought. https://chandra.harvard.edu/resources/podcasts/media/pod100326.mp3 /resources/podcasts/ts/ts100326_hd.html Tue, 10 Mar 2026 12:00:00 EST A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. https://chandra.harvard.edu/resources/podcasts/media/pod250226.mp3 /resources/podcasts/ts/ts250226_hd.html Wed, 25 Feb 2026 12:00:00 EST To commemorate a six-planet alignment in late February 2026, Chandra released sonifications of three of those planets: Jupiter, Saturn, and Uranus. https://chandra.harvard.edu/resources/podcasts/media/pod230226.mp3 /resources/podcasts/ts/ts230226_hd.html Mon, 23 Feb 2026 12:00:00 EST This image contains the first "astrosphere," or wind-blown bubble, that astronomers have captured surrounding a star that is a younger version of our Sun. https://chandra.harvard.edu/resources/podcasts/media/pod280126.mp3 /resources/podcasts/ts/ts280126_hd.html Wed, 28 Jan 2026 12:00:00 EST A new discovery captures the cosmic moment when a galaxy cluster started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought. https://chandra.harvard.edu/resources/podcasts/media/pod230126.mp3 /resources/podcasts/ts/ts230126_hd.html Fri, 23 Jan 2026 12:00:00 EST Like a recording artist who has had a long career, Chandra has a "back catalog" of cosmic recordings that is impossible to replicate. 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.
