Selected Chandra Articles & Media HighlightsThis is a sample of the news coverage the Chandra X-ray Observatory has received during this quarter. To read the story and learn about copyright policies, please visit the individual publication's website or your local library. June 2002 Publication: Dallas Morning News (June 24, 2002; p. C3.) Headline: Learning to Read X-rays: 40 Years of Study Has Yielded Wealth of Data About Invisible Realms Byline: Alexandra Witze Selected Text: Forty years ago this month, above New Mexico's White Sands Proving Grounds, a rocket flew into the skies in search of X-rays from the moon. Instead, the experiment opened a new era in astronomical research ... Today, astronomers have much more sensitive telescopes than that first discovery rocket over White Sands. New data are flowing from two major orbiting X-ray telescopes: NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton satellite. Publication:Pittsburgh Post-Gazette (June 5, 2002; p. A3) Headline: Galaxies Are Littered with Sources of X-rays Byline: Byron Spice Selected Text: Astronomers have pointed two orbiting X-ray observatories at the same patch of seemingly blank sky and, once they eliminated the X-ray glare of distant quasars, have found galaxies glittering with X-ray sources ... Griffiths yesterday presented findings from deep surveys using NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton satellite during a news conference at the American Astronomical Society meeting in Albuquerque, N.M. May 2002 Publication: Bangor Daily News (May 30, 2002; Section B, Pg. 1) Headline: Astronomer Aims to Rekindle 'Wow' for Nonscientists Byline: Tom Weber Selected Text: We are living in the golden age of astronomy. Every few weeks, it seems, we are granted yet another wondrous new glimpse at the beginnings of the universe. Telescopes such as the Hubble, the Chandra X-Ray and others are our modern time machines, the unblinking eyes that provide us mere mortals a line of sight through the cosmos itself.
Headline: The Quirks of Quark Byline: Wayne Falda Selected Text: Our wildly bizarre universe may be stranger than we ever thought. The cosmos that we know already is a mind-bending swirl of galaxies, titanic eruptions of high-energy gamma rays deep in space, and tiny particles popping in and out of existence with every teeny energy fluctuation in the cosmic void. Now things have gotten really odd, with strong hints that there are heavenly bodies way, way out there made up of strange quarks ... Using the powerful Chandra X-ray Observatory in space, the astronomers claim to have found two stars made out of strange quarks. April 2002 Publication: US News & World Report (April 22, 2002) Headline: Starry, Starry Night Byline: Lisa Stein Selected Text: Stars, planets, people--at bottom they're all the same stuff. You know, protons, neutrons, electrons. Now astronomers think they've found a couple of glaring exceptions: two city-size chunks of an entirely new form of matter. Both are the superdense corpses of stars many times heavier than the Sun. Astronomers call these hulks neutron stars. But stars made of neutrons are limited--so to speak--to a density of about a billion tons per teaspoonful. Observations by NASA's orbiting Chandra X-ray telescope imply that these two are several times denser. Publication: New York Times (April 11, 2002) Headline: Stars Suggest a Quark Twist and a New Kind of Matter Byline: John Noble Wilford Selected Text: Observations of two stars, one unusually small and the other unusually cold, have led astronomers to think they are seeing evidence of a new form of matter and a new kind of star, one possibly made of elementary particles known as quarks and denser than any cosmic object other than a black hole. As a group, quarks are building blocks of larger particles and are normally bound together as protons and neutrons. Now it appears that a certain combination of these quarks are capable of a more independent existence as "strange quark matter" inside quark stars. Astronomers said yesterday that if their interpretation was correct, the new findings were startling and exciting because they promised to open a new window on the nature of matter on the tiniest scales. Publication: Orlando Sentinel (April 11, 2002) Headline: Odd Stars May Shake Up Science Byline: Gwyenth Shaw Selected Text: Scientists said Wednesday that they may have discovered an entirely new form of matter, which, if true, would be a giant leap forward in the effort to understand the universe. Using NASA's orbiting Chandra X-ray Observatory, astronomers were looking for neutron stars that are formed in the wake of an exploding supernova. Instead, they were stunned to discover something radically different. What they found were two collapsing stars -- one very small and the other incredibly cold -- that could contain a type of matter no one has seen before.
