Sloan Digital Sky Survey Supports Dark Energy as the Primary Constituent of the Universe
This figure shows the SDSS spectrum of a quasar at a distance of 12 billion light years.
Chandra Looks Over a Cosmic Four-Leaf Clover
The Cloverleaf quasar is a single object whose image has been reproduced four times in a cloverleaf-like arrangement through a process known as gravitational lensing.
Making Black Holes Go 'Round on the Computer
Credit: Bruegmann, Tichy, Jansen 2004 Black hole binary after about one orbit. The black surfaces represent the black holes; whatever falls behind this black hole "horizon" can never escape again. The colored plane shows a measure for the distortion of spacetime. The numerical method has succeeded in keeping the data smooth and undistorted.
