Materials Black Holes - Falling Into (Hamilton) Provides animations to illustrate the effects of black holes. 3-01 News Chandra X-ray Observatory (Harvard-Smithsonian Center for Astrophysics) Provides the latest news on the X-ray observatory for space, black holes, and pioneering explorations using very high resolution methods. 9-00 Papers Black Hole Pulls a Star in Orbit of Galaxy (USA Today - Vergano) "Astronomers using the Hubble Space Telescope have captured evidence of a black hole hurtling through our Milky Way galaxy with gravity so strong it's dragging a star with it." 11-02 Black Holes (KidsAstronomy.com) Provides a diagram and description of a black hole, singularity, and event horizon. 11-00. Black Holes (Wikipedia.org) "A black hole is a concentration of mass with a gravitational field so strong that the escape velocity from nearby points exceeds the speed of light." 10-04 Black Holes Galore (Time.com) "Theory says that most of the galaxies formed shortly after the Big Bang should have giant black holes lurking in their cores--but until now, astronomers haven't seen much evidence." 10-07 Black Holes Merge When Galaxies Collide (Scientific American) Provides the theory, based on observations, that when galaxies collide, black holes at their centers merge. 7-02 Event Horizon (Wikipedia.org) "An event horizon is a boundary in spacetime for a given observer beyond which no information, including light, can reach the observer. The most famous example is a black hole, which for a distant and stationary observer (such as someone at Earth) is surrounded by an event horizon." 10-04 Galaxy Blasted by a Black Hole (MSNBC News) "A powerful jet of particles from a "supermassive" black hole has been seen blasting a nearby galaxy, according to findings from the US space agency." 12-07 Interferometry (University of Colorado - Cash) Explains a method of "seeing" that uses X-rays and is up to a thousand times more powerful than other methods (that use visible light) for studying distant objects. A special focus of this science is to see "black holes." 9-00 New Twist on Black Hole Theory (RedOrbit.com) "Professor Sam Braunstein, of the University of York’s Department of Computer Science, and Dr Arun Pati, of the Institute of Physics, Sainik School, Bhubaneswar, India, have established that quantum information cannot be ‘hidden’ in conventional ways, or in Braunstein’s words, 'quantum information can run but it can’t hide.' " "This result gives a surprising new twist to one of the great mysteries about black holes." "Dr Pati said: 'Our result shows that either quantum mechanics or Hawking’s analysis must break down, but it does not choose between these two possibilities.' " 02-07 Questions About Black Holes (ASK and Astronomer for Kids) Provides questions and answers for kids and adults. 01-06 Scientist May Have Created a Black Hole (BBC News) "A fireball created in a US particle accelerator has the characteristics of a black hole, a physicist has said." "It was generated at the Relativistic Heavy Ion Collider (RHIC) in New York, US, which smashes beams of gold nuclei together at near light speeds." "The Brown researcher thinks the particles are disappearing into the fireball's core and reappearing as thermal radiation, just as matter is thought to fall into a black hole and come out as 'Hawking' radiation." 3-05 Scientists Create Virtual Telescope 1000 Times Finer Than Hubble (Science Daily) "An international team, led by astronomers at the MIT Haystack Observatory, has obtained the closest views ever of what is believed to be a super-massive black hole at the center of the Milky Way galaxy." 09-08 Supermassive Black Hole (Wikipedia.org) "A supermassive black hole is a black hole with a mass in the range of millions or billions solar masses." 10-04
