Supernovas: When Stars Die Posted by: cxcpub
Video duration: 279 seconds 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.

Black Holes: Tall, Grande, Venti Posted by: cxcpub
Video duration: 338 seconds 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.

The Giant Planets: X-ray Secrets Revealed Posted by: cxcpub
Video duration: 253 seconds 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. Related: chandra, jupiter, saturn, x-ray |

Until Their Dying Day: Stars on the Brink Posted by: cxcpub
Video duration: 231 seconds 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.

The Exotic World of Neutron Stars Posted by: cxcpub
Video duration: 262 seconds 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. Related: astronomy, chandra, neutron, stars, x-ray |

Putting Chandra In Its Place Posted by: cxcpub
Video duration: 226 seconds 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.

Giants of the Universe Probe Cosmic Questions Posted by: cxcpub
Video duration: 325 seconds 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.

Chandra, Not Your Backyard Telescope Posted by: cxcpub
Video duration: 345 seconds 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.

How Chandra Does What It Does Posted by: cxcpub
Video duration: 244 seconds NASA's Chandra X-ray Observatory, in orbit since 1999, studies the high-energy Universe, where black holes, exploding stars, and mysterious matter hold sway. Related: astronomy, astrophysics, chandra, nasa, x-ray |

Snowball Fight in the Solar System Posted by: cxcpub
Video duration: 276 seconds 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? Related: chandra, comets, dirty, snowballs, x-rays |

In A Galaxy Far, Far Away and Also Those Nearby Posted by: cxcpub
Video duration: 303 seconds "In a galaxy far, far away..." 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?

Sombrero Galaxy in 60 Seconds (in HIGH DEFINITION) Posted by: cxcpub
Video duration: 106 seconds Like the Milky Way, Sombrero is a spiral galaxy. However, we see Sombrero edge-on from our vantage point from Earth, rather than the face-down perspective that is more familiar. Related: astronomy, astrophysics, chandra, nasa, satellite, x-ray |

Just Two Numbers Is All You Need Posted by: cxcpub
Video duration: 376 seconds Black holes sound wildly complicated. After all, there are all sorts of bizarre things going on: intense gravity, the warping of the fabric of space, the distortion of time itself. But when it comes to describing black holes, it comes down to just two numbers: the mass of the black hole and its spin. Related: astronomy, astrophysics, chandra, nasa, satellite, x-ray |

Cassiopeia A in 60 Seconds (in HIGH DEFINITION) Posted by: cxcpub
Video duration: 67 seconds Cassiopeia A is the 300-year-old remnant created by the supernova explosion of a massive star. Each Great Observatory image highlights different characteristics of the remnant. Related: astronomy, astrophysics, chandra, nasa, satellite, x-ray |

Chapter 4: Eta Carinae (in AUDIO ONLY) Posted by: cxcpub
Video duration: 207 seconds Of the estimated three hundred billion stars in our galaxy, Eta Carinae may well be the biggest and brightest of them all. Weighing in at 150 times the mass of our Sun, it is five million times as luminous! Related: astronomy, astrophysics, chandra, nasa, satellite, x-ray |
