First LHC proton collisions postponed further
The world’s most powerful atom smasher won’t reopen for business until the end of June at the earliest, rather than in April as scientists had previously estimated.

Debates over definition of planet continue and inspire
Planetary science is in the midst of a revolution. As recently as the early 1990s, “the planets” consisted of just nine famous objects in our solar system that every school kid learned to recognize by name and appearance. But then, advances in astronomical technology unleashed an explosion of new planetary discoveries on two fronts. One […]

Water-ice deposits found beneath Martian hills
Using radar from an orbiting spacecraft to penetrate the hidden recesses of Mars, planetary prospectors have uncovered vast reserves of water-ice buried beneath rocky debris.

Misplaced muons either mundane or monumental
During an experiment in Fermilab's Tevatron particle accelerator, a group of elementary particles called muons showed up in a strange place. Physicists are considering the likely implications.
