• The smooth and youthful skin of a baby neutron star

  
  Ars Technica — Authority: 758
  Neutron stars are some of the densest objects in existence, only beaten out by black holes. Neutron stars are something of a paradox. They are inherently simple, their formation being governed by a rather straightforward competition between quantum mechanics and gravity. This clean system and its resulting dynamics ...

• Colliding White Dwarfs May Mimic Supernovae Used to Gauge Astronomical Distances

  
  Scientific American — Authority: 149
  Stellar explosions known as type Ia supernovae have proved invaluable to astrophysicists as markers of cosmic distance. Their brightness and consistency in observed properties allow astronomers to use them as "standard candles" to determine distances to objects in the sky. Just a decade ago type Ia supernovae took ...

• Einstein’s Theory of Gravity and the Problem of Missing Mass

  
  Physics and Physicists — Authority: 499
  There is a very good review of the current progress in the theory of Modified Newtonian Dynamics (MOND) in the current issue of Science[1]. Abstract: The observed matter in the universe accounts for just 5% of the observed gravity. A possible explanation is that Newton’s and Einstein’s theories of gravity fail ...

• Tweak Gravity: What If There Is No Dark Matter?

  
  Scientific American — Authority: 149
  Theorists and observational astronomers are hot on the trail of dark matter , the invisible material thought to account for puzzling mass disparities in large-scale astronomical structures. For instance, galaxies and galactic clusters behave as if they were far more massive than would be expected if they comprised ...

• Emission Impossible?: Is Dark Matter Behind the Hazy Radiation at the Milky Ways Center?

  
  Scientific American — Authority: 149
  A haze of radiation at the heart of the Milky Way Galaxy that appears in sky maps taken by two spacecraft at two different wavelengths likely results from a population of high-energy electrons, according to a new analysis of gamma rays in the galaxy. Curiously, some researchers maintain, those electrons are not ...

• The Long-Lost Siblings of the Sun (preview)

  
  Scientific American — Authority: 149
  People have often sought solitude in the starry night sky, and it is an appropriate place for that. The night is dark because, in cosmic terms, our sun and its family of planets are very lonely. Neighboring stars are so far away that they look like mere specks of light, and more distant stars blur together into a ...
