An underground detector in a South Dakota mine has failed to find dark matter particles, casting doubt on earlier claims

The recently proposed idea of “black hole firewalls” has physicists questioning some of their most cherished ideas

The influential Large Underground Xenon experiment, a dark matter detector based in South Dakota, is set to release its first results

Physicists have completed a new round of searches for the answer to why matter dominates antimatter. But the radioactive decay that would solve the puzzle evades them

The latest observations of exploding stars could call into question the cosmological constant explanation of dark energy

"Hair" is a term among physicists as a stand-in for any other measure needed to describe a black hole other than its mass, its angular momentum and its electric charge

Observations show two planets circling their star's equator at a 45-degree angle

From the agencies to Antarctica, work picked up anew

Although the two bodies have significant differences, researchers point to surprising similarities in their topographical evolution

Hubble observations of the smallest galaxies known help explain why so few of them exist

A computer simulation of the universe shows that it may be filled with “defects in spacetime”

The 2013 Nobel Prize in Physics goes to François Englert and Peter Higgs for the theory of how particles acquire mass, requiring the existence of the Higgs Boson, experimentally confirmed to exist in 2012
