Faint cosmic glow appears to be remnant radiation from first stars or black holes born in our universe

Particulate materials captured from the comet Wild 2 have revealed clues about the birth of our solar system that counter some of the basic theories that the solar nebular is gently collapsing inward to form the sun and the planets.

The stars and gas which are seen in galaxies account for only a few percent of the gravitating material in the Universe.

Subatomic particle appeared without its antimatter partner, says physicist Ann Heinson, co-leader of group of 50 scientists

Scientists using NASA's Hubble Space Telescope have discovered that dark energy is not a new constituent of space, but rather has been present for most of the universe's history.

A fast, efficient image enhancement technique developed at the National Institute of Standards and Technology (NIST) and originally applied to improving monochrome microscope images has proved itself equally effective at the other end of the scale sharpening details on color images of distant galaxies produced by the Hubble Space Telescope.

NASA's announcement yesterday of evidence that water still flows on Mars, at least in brief spurts, demonstrates that the view of Mars as a very dry planet should be reevaluated, says Dawn Sumner, professor of geology at UC Davis. Recent work from by Sumner and graduate student Greg Chavdarian also supports the presence of liquid water near the surface.
