Massive black holes halt star birth in distant galaxies
Astronomers, using the European Space Agency's (ESA) Herschel Space Observatory, have shown that the number of stars that form during the early lives of galaxies may be influenced by the massive black holes at their hearts. View More (2012-05-10)
New technique uses electrons to map nanoparticle atomic structures
With dimensions measuring billionths of a meter, nanoparticles are way too small to see with the naked eye. Yet it is becoming possible for today's scientists not only to see them, but also to look inside at how the atoms are arranged in three dimensions using a technique called nanocrystallography.

Fermi Observations of Dwarf Galaxies Provide New Insights on Dark Matter
There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. View More (2012-04-03)
Titanium paternity test fingers Earth as moon's sole parent
A new chemical analysis of lunar material collected by Apollo astronauts in the 1970s conflicts with the widely held theory that a giant collision between Earth and a Mars-sized object gave birth to the moon 4.5 billion years ago. View More (2012-03-30)
