    "Astronomy is a natural science that is the study of celestial objects (such as moons, planets, stars, nebulae, and galaxies), the physics, chemistry, and evolution of such objects, and phenomena that originate outside the atmosphere of Earth, including supernovae explosions, gamma ray bursts, and cosmic background radiation."

Bolshoi Simulation | Home - 0 views

  •  
    The Bolshoi simulation is the most accurate cosmological simulation of the evolution of the large-scale structure of the universe yet made ("bolshoi" is the Russian word for "great" or "grand").  The first two of a series of research papers describing Bolshoi and its implications have been accepted for publication in the Astrophysical Journal. The first data release of Bolshoi outputs, including output from Bolshoi and also the BigBolshoi or MultiDark simulation of a volume 64 times bigger than Bolshoi, has just been made publicly available to the world's astronomers and astrophysicists.

[0904.0402] A thermodynamic basis for prebiotic amino acid synthesis and the nature of ... - 0 views

  •  
    Of the twenty amino acids used in proteins, ten were formed in Miller's atmospheric discharge experiments. The two other major proposed sources of prebiotic amino acid synthesis include formation in hydrothermal vents and delivery to Earth via meteorites. We combine observational and experimental data of amino acid frequencies formed by these diverse mechanisms and show that, regardless of the source, these ten early amino acids can be ranked in order of decreasing abundance in prebiotic contexts. This order can be predicted by thermodynamics. The relative abundances of the early amino acids were most likely reflected in the composition of the first proteins at the time the genetic code originated. The remaining amino acids were incorporated into proteins after pathways for their biochemical synthesis evolved. This is consistent with theories of the evolution of the genetic code by stepwise addition of new amino acids. These are hints that key aspects of early biochemistry may be universal.

Gaia Archive - 0 views

  •  
    "Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy. Gaia will provide unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group. This amounts to about 1 per cent of the Galactic stellar population. "

New Particle Collider Operating in Secret - NYTimes.com - 0 views

  • "We may not have created a black hole, but it seems we may have discovered a way for elementary particles to shape the path of evolution. You just never know what you are going to find"

      I am no arbiter of humour, but I think this April Fool prank is fairly lame (unless there is truth in the unlikely twitter rumour that the NYT was pranked)

Know When Milky Way Collision Occur - 0 views

  •  
    NASA scientist have found proof that our Milky Way had an encounter with a small galaxy or massive dark matter structure perhaps as recently as 100 million years ago. Are you also interested to know how galaxies form, evolve and interact?
