Imagine cruising the heavens from your desktop and seeing all the spectacular images from NASA's Hubble Space Telescope. Exploding stars and faraway galaxies are just a mouse click away through Sky in Google Earth.

Using a map of more than 4,000 luminous quasars in the distant universe, scientists from the Sloan Digital Sky Survey (SDSS-II) have shown that these brilliant beacons are strongly clumped, with huge quasar superclusters separated by vast stretches of empty space. The strong clustering shows that the quasars lie within massive concentrations of dark matter.

A long, slender stream of ancient stars has been discovered racing across the northern sky. The stream is about 30,000 light-years distant from Earth and is flowing high over the Milky Way Galaxy at some 230 kilometers per second, or more than half a million miles per hour.

Astronomers from the University of Nottingham, UK, and the Instituto de Astrofisica de Canarias (Spain), have found the first observational evidence that galaxies are not randomly oriented.

Astronomers have found a relatively tiny galaxy whose black-hole-powered "central engine" is pouring out energy at a rate equal to that of much larger galaxies, and they're wondering how it manages to do so.

A huge but very faint structure, containing hundreds of thousands of stars spread over an area nearly 5,000 times the size of a full moon, has been discovered and mapped by astronomers of the Sloan Digital Sky Survey (SDSS-II).

As Albert Einstein developed his theory of general relativity nearly a century ago, he proposed that the gravitational field from massive objects could dramatically warp space and deflect light.

Researchers from the Max Planck Institute for biophysical Chemistry in Göttingen establish a new law allowing unlimited optical resolution in fluorescence microscopy.

An international team of astrophysicists led by researchers at the Max Planck Institute for Astrophysics presents the worldwide largest simulation of the universe and an accurate theoretical model for the growth of galaxies and supermassive black holes.

In the largest galaxy survey ever, the Sloan Digital Sky Survey (SDSS) confirmed the role of gravity in growing structures in the universe, using the result to precisely measure the geometry of the universe.
