The Universe Darkly /resources/podcasts/ts/ts022908.html /resources/podcasts/ts/ts022908.html Fri, 29 Feb 2008 12:00:00 EST When you look up at the night sky, you see a lot of things glowing like stars, planets, and galaxies. So it might sound strange to hear that most of the Universe is actually dark. The truth is the protons, neutrons and electrons that make up everything we can see, and that means everything with telescopes we've got, accounts for only about 4% of the mass and energy of the Universe. The rest is dark and mysterious. More specifically, about 70% of the Universe is what is known as dark energy; about 26% is so-called dark matter. Modern day astronomers have developed many tactics to explore the dark Universe, including using telescopes like Chandra.

Chandra in the (Google) Sky /resources/podcasts/ts/ts290108.html /resources/podcasts/ts/ts290108.html Tue, 29 Jan 2008 12:00:00 EST Astronomy is truly in a golden age. With a fleet of space-based observatories, including the Chandra X-ray Observatory, astronomers now have a suite of amazing tools to study the Universe. Simultaneously to this bonanza in astronomy has been the growth and expansion of the Internet. Think back to before 1990. The Internet was barely a rumor and there were no Great Observatories! But now people are taking advantage of these two seemingly separate advances to do some amazing things What's in a Name? /resources/podcasts/ts/ts020108.html /resources/podcasts/ts/ts020108.html Wed, 02 Jan 2008 12:00:00 EST Names in astronomy don't always tell the whole story. Let's take, for example, radio galaxies. Why, might you ask, would a Chandra podcast talk about such an object? The answer is that radio galaxies are, yes, very bright in radio emission. But they are also powerful emitters of X-rays, optical light and from other parts of the electromagnetic spectrum. More than that, they are important objects that really have played a very big role in how the Universe has evolved. The Truth and Lies about Black Holes /resources/podcasts/ts/ts301107.html /resources/podcasts/ts/ts301107.html Fri, 30 Nov 2007 12:00:00 EST Black holes have a bad reputation. After all, something that could swallow you completely sounds pretty scary. They're invisible, so maybe there's one just around the corner and we dont know it! Also, arent they enormous vacuum cleaners capable of destroying anything that gets near them? Once the black hole starts pulling on something, isnt that just a one-way ticket to oblivion? Well, not all of these things are exactly true. When Will History Repeat Itself? /resources/podcasts/ts/ts311007.html /resources/podcasts/ts/ts311007.html Wed, 31 Oct 2007 12:00:00 EST Astronomers think that a supernova should go off in our own Milky Way galaxy every 50 years or so. When was the last one we've seen? Probably 1604. Yes, that's over 400 years ago. This being astronomy however, things will undoubtedly average out over the long run, but in the meantime, we're left without a recent supernova in our Galaxy to study. Luckily for us, astronomers from previous centuries were on the case.

These are some of the most famous words in movie history. But what do we already know about galaxies, and what do astronomers, like those using the Chandra X- ray Observatory, still hope to learn about them? From First Light to Eighth Anniversary /resources/podcasts/ts/ts240807.html /resources/podcasts/ts/ts240807.html Fri, 24 Aug 2007 12:00:00 EST Chandra's launch aboard the Space Shuttle Columbia on July 23, 1999, was obviously a very important event. However, you might say it wasn't until about a month later that the Chandra mission really got started. In late August, after weeks of getting the spacecraft into the correct orbit and testing out various aspects of the satellite, Chandra was ready for its debut to the public. This was Chandra's First Light. Chandra's director, Dr. Harvey Tananbaum, explains the significance of that early image. How It All Started /resources/podcasts/ts/ts072607.html /resources/podcasts/ts/ts072607.html Thu, 26 Jul 2007 12:00:00 EST Just after midnight on July 23, 1999, the Space Shuttle Columbia launched in orbit with the heaviest payload ever carried by a shuttle. Its precious cargo was the Chandra X-ray Observatory, which has helped revolutionize our understanding of the Universe. Mergers And Acquisitions In The Cosmos /resources/podcasts/ts/ts280607.html /resources/podcasts/ts/ts280607.html Thu, 28 Jun 2007 12:00:00 EST News about mergers is usually found in the business section. But many objects in the Universe, from black holes to clusters of galaxies, are also prone to mergers. Like the corporate world, cosmic mergers are dictated by where the most assets lie. The Bigger They Are, The Harder They Fall /resources/podcasts/ts/ts240507.html /resources/podcasts/ts/ts240507.html Thu, 24 May 2007 12:00:00 EST When you look at the night sky, stars look like permanent fixtures of light. However, stars are born, live for a period of time, and then ultimately die. How they die is directly linked to how massive they were when they were born. The Exotic World of Neutron Stars /resources/podcasts/ts/ts300407.html /resources/podcasts/ts/ts300407.html Mon, 30 Apr 2007 12:00:00 EST Neutron stars are created when a massive star runs out of fuel and collapses. As the star collapses, the density becomes so immense that protons and electrons are squeezed tightly together to form neutrons. The end result is a star only 20 km across but weighing 1 1/2 times more than our sun and made up mostly of neutrons. The Giant Planets: X-ray Secrets Revealed /resources/podcasts/ts/ts190307.html /resources/podcasts/ts/ts190307.html Mon, 19 Mar 2007 12:00:00 EST Jupiter and Saturn are the two largest planets in our Solar System, best known for very different reasons. Most people think of Jupiter's famous Great Red Spot, while Saturn is, of course, most loved for those excellent rings. These two planets, however, offer much, much more for astronomers looking to learn more about our Solar System.

Looking at the light from stars is exactly how astronomers can learn about them. Snowball Fight in the Solar System /resources/podcasts/ts/ts220107.html /resources/podcasts/ts/ts220107.html Mon, 22 Jan 2007 12:00:00 EST One of the most surprising objects observed in X-rays are comets. X-rays are normally associated with the hottest things in the Universe, such as black holes. Comets, however, were described by Fred Whipple as being "dirty snowballs". So how does a snowball make X-rays? Black Holes: Tall, Grande, Venti /resources/podcasts/ts/ts291206.html /resources/podcasts/ts/ts291206.html Sun, 31 Dec 2006 12:00:00 EST Long before astronomers found evidence that black holes existed, these exotic objects have captured imaginations. In the 21st century, scientists not only have proof that black holes are real, they continue to make startling discoveries both about individual black holes examples and about their populations across the Universe. Giants of the Universe Probe Cosmic Questions /resources/podcasts/ts/ts301106.html /resources/podcasts/ts/ts301106.html Thu, 30 Nov 2006 12:00:00 EST Clusters of galaxies are the largest structures in the Universe that are held together by gravity. Because of their immense size and mass, galaxy clusters are extremely useful as tools to probe a variety of questions about the Universe as a whole as well as properties of the clusters themselves. Supernovas: When Stars Die /resources/podcasts/ts/ts301006.html /resources/podcasts/ts/ts301006.html Mon, 30 Oct 2006 12:00:00 EST When a star explodes, it leaves behind a debris field of stellar material and high-energy particles known as a supernova remnant. Astronomers use Chandra to study these remnants that can produce intense X-ray radiation for thousands of years. Supernova remnants are responsible for seeding cloud that formed our Sun, planets, and ultimately us with elements like nitrogen and oxygen. Until Their Dying Day: Stars on the Brink /resources/podcasts/ts/ts260906.html /resources/podcasts/ts/ts260906.html Tue, 26 Sep 2006 12:00:00 EST Supernovas are the remnants of catastrophic explosions, and they are among the favorite targets of scientists who use Chandra, for good reason too. Supernovas and their remnants have proven to be extremely important in understanding topics ranging from the birth of our Solar System to the history and composition of the Universe itself. Peering into the Heart of the Milky Way /resources/podcasts/ts/ts300806.html /resources/podcasts/ts/ts300806.html Thu, 31 Aug 2006 12:00:00 EST Humanity has long sought to learn about the Milky Way, our home galaxy. Even after the advent of optical telescopes, the Milky Way's center remained mysterious because gas and dust blocks most visible light along our line of sight. Fortunately, X-ray telescopes like Chandra can detect higher-energy radiation that penetrates this veil of galactic debris. Putting Chandra In Its Place /resources/podcasts/ts/ts260706.html /resources/podcasts/ts/ts260706.html Thu, 27 Jul 2006 12:00:00 EST How the Chandra X-ray Observatory fits into the modern astronomer's toolkit. Chandra is one of NASA's "Great Observatories". The Great Observatories were four missions selected by NASA to explore different types of radiation and really tackle the biggest questions in astronomy. Chandra, Not Your Backyard Telescope /resources/podcasts/ts/ts090606.html /resources/podcasts/ts/ts090606.html Fri, 09 Jun 2006 12:00:00 EST X-ray telescopes like Chandra are not like the telescopes you find in backyards or at the local observatory. In addition to being above the Earth's atmosphere, they need to have special mirrors to detect the X-rays that pass through most objects.
