Headline: New NASA Film Captures Mysterious Antimatter -- Sort of: Movie on Internet Shows Cosmic Heartbeat of Star that Exploded 7,000 Years Ago Byline: Tom Spears Selected Text: Now you too can watch how antimatter swooshes across the galaxy in a new movie from NASA available free on the Internet. All that's missing is the popcorn -- and, actually, the antimatter, even though NASA is sure it's there, and in vast quantities. Like the monster that stays off-camera in the best science fiction flicks (think of Alien) the antimatter itself is just out of sight. Neither of NASA's most powerful telescopes, the Hubble Space Telescope and the Chandra X-ray Observatory, can see it. But you can see where the antimatter goes and what it does as it travels at half the speed of light, 150,000 kilometres per second, causing circular ripples in the surrounding cloud of gases like a stone hitting still water. Publication: Agence France Presse (September 21, 2002) Headline: NASA Film Depicts Life of Crab Pulsar Selected Text: NASA has made a grand entry into the world of cinema, publishing the first moving images of the "Crab Pulsar," a seconds-long clip of the rapidly rotating neutron star the size of Manhattan Island. "Through this movie, the Crab Nebula has come to life," exulted Jeff Hester of Arizona State University in Tempe. "We can see how this awesome cosmic generator actually works." The film, released Thursday, is a composite of observations taken over many months by NASA's orbiting Chandra X-ray Observatory and the orbiting Hubble telescope and "reveals features never seen in still images," according to the space agency. Publication: Washington Post (September 20, 2002; p. A3) Headline: Astronomers Create Pulsar Movie Portrait Byline: William Harwood Selected Text: Astronomers using NASA's most powerful space telescopes have produced an unprecedented time-lapse movie showing the eerily pulsing, still-beating heart of a star that exploded a thousand years ago. The movies are expected to serve as real-world tests for theories that attempt to explain how these unimaginably powerful dynamos evolve and interact with the surrounding space environment. "The remarkable thing here is we are getting to see, before our eyes, what's happening in a truly extraordinary environment, an environment that is nothing like we know in our everyday lives," Jeff Hester, an astronomer at Arizona State University, said yesterday. Hester and a team of astronomers used the Hubble Space Telescope and the Chandra X-ray Observatory to make repeated photographs of the inner regions of the Crab nebula, the remnants of a supernova first observed by Chinese astronomers in 1054.

Headline: First Sighting of the Event Horizon Byline: Robin Orwant Selected Text: Black holes really do imprison matter and light, and sap energy from light that narrowly escapes their grip. Until now, these were only predictions of Einstein's theory of gravity. But astronomers peering at suspected black holes have at last found compelling evidence that this does actually happen ... The astronomers studied a supermassive black hole with a mass 23 million times that of the Sun. They looked at fine detail in the broad spectral fingerprint of iron using NASA's Chandra X-ray satellite and the European Space Agency's XMM-Newton satellite.
Headline: Bull's Eye Byline: Edited by Bruce A. Smith Selected Text: Astronomers have used data from the Chandra X-ray Observatory and the Arecibo Radio Telescope to find a neutron star at the center of a bright ring of high-energy particles in the remains of a distant supernova. The discovery offers clues to the way nature converts the energy of a rotating neutron star into extremely high-energy particles.
