This never-before-seen view of the turbulent heart of our Milky Way combines a near-infrared view from Hubble, an infrared image from Spitzer, and X-ray data from Chandra. http://www.chandra.harvard.edu/photo/2009/galactic/ http://chandra.harvard.edu/resources/podcasts/hd/index.html

Cassiopeia A is a supernova remnant found embedded in the constellation that bears its name, which is known as the queen in Greek mythology. http://chandra.harvard.edu/photo/2009/cassio/ http://chandra.harvard.edu/resources/podcasts/hd/index.html

NGC 6240 is a system in which two supermassive black holes are a mere 3,000 light years apart, virtually nothing in astronomical terms. http://chandra.harvard.edu/photo/2009/ngc6240/ http://chandra.harvard.edu/resources/podcasts/hd/index.html

This image from the Chandra X-ray Observatory reveals a wealth of exotic objects and high-energy features at the center of our Milky Way galaxy. http://chandra.harvard.edu/photo/2009/gcenter/ http://chandra.harvard.edu/resources/animations/featured_anim.html#anim_219 http://chandra.harvard.edu/resources/podcasts/hd/index.html

This composite image of the Hydra A galaxy cluster shows 10-million-degree gas observed by Chandra and jets of radio emission observed by the Very Large Array. http://www.chandra.harvard.edu/photo/2009/hydra/ http://chandra.harvard.edu/resources/podcasts/hd/index.html

A new study from two of NASA's "Great Observatories" provides fresh insight into how some stars are born, along with a beautiful new image of a stellar nursery in our own Milky Way Galaxy. http://chandra.harvard.edu/photo/2009/cepb/ http://chandra.harvard.edu/resources/podcasts/hd/index.html

The supernova remnant known as E0102 was one of the targets that Chandra first observed after its launch in 1999. http://chandra.harvard.edu/resources/podcasts/sd.html http://www.chandra.harvard.edu/photo/2009/e0102/

This beautiful image gives a new look at Stephan's Quintet, a compact group of galaxies discovered about 130 years ago and located about 280 million light years from Earth. http://chandra.harvard.edu/resources/podcasts/sd.html http://chandra.harvard.edu/photo/2009/stephq/

We start with an optical and infrared image that shows the crowded area around the object known as GRS 1915+105, or GRS 1915 for short.

This image contains one of the most complex galaxy clusters known, which is located about 5.4 billion light years from Earth. To learn more click here: http://chandra.harvard.edu/photo/2009/macs/

This episode will touch on some of the areas in which astronomers hope X-ray telescopes will push our knowledge forward in the years to come.

Chandra's X-ray image of the Tarantula Nebula gives scientists a close-up view of the drama of star formation and star evolution. http://chandra.harvard.edu/photo/2008/30dor/

A small dense object is responsible for the remarkably complex and intriguing structures seen in this image from the Chandra X-ray Observatory. http://www.chandra.harvard.edu/photo/2009/b1509/ http://chandra.harvard.edu/resources/podcasts/hd/index.html

NGC 604 is a divided neighborhood in the galaxy M33, where some 200 hot, young massive stars reside.

The Crab Nebula is one of the best-known images ever taken by the Chandra X-ray Observatory. http://chandra.harvard.edu/resources/podcasts/hd/index.html http://www.chandra.harvard.edu/photo/2008/crab/

This image of the spiral galaxy Messier 101 is a composite of observations from NASA's three Great Observatories. http://chandra.harvard.edu/photo/2009/m101/

The composite image shows the galaxy cluster known as Abell 85, which is located about 740 million light years from Earth.

This visualization shows a fly-through of Cas A based on the 3-D representation constructed from Chandra and Spitzer data. It begins with an artists rendition of the neutron star previously detected by Chandra. Next, new features unseen in traditional 2-D data sets are visible, including details of how the parent star exploded. The green region is mostly iron observed in X-rays; the yellow region is mostly argon and silicon seen in X-rays, optical and infared; the red region is cooler debris seen in the infared and the blue region is the outer blast wave, most prominent in X-rays.

This movie has been created from a series of X-ray observations from Chandra of Cassiopeia A (Cas A) over eight years. It begins with a full-field view of Cas A, cycling through the movie several times. The camera then zooms into three different areas of Cas A where evolution of different features can been seen. This movie - the first of its kind for a supernova remnant - reveals new details about the supernova explosion and its remnant seen today. [Runtime: 02:00] (Credit: NASA/CXC/SAO/D.Patnaude et al.)
