A study suggests atoms can bond not only with electrons in their outer shells, but also via those in their supposedly sacrosanct inner shells
The previously unknown microbe was tough enough to survive stringent sterilization at two locations. Might it survive a trip to Mars?
Where did the Red Planet’s carbon dioxide blanket and liquid surface water go? NASA’s Maven mission will launch next week to investigate
The most precise measurement yet of the electron’s shape casts doubt on ideas such as supersymmetry that predict a zoo of undetected particles in the universe
Researchers have measured the extent of the historic meteor’s damage and calculated the asteroid’s precise trajectory
NASA’s premier planet-hunting scope turns up 647 possible Earth-sized worlds in the Milky Way
This month Comet ISON will fly by the sun in an encounter that could destroy the object, or elevate it to greatness
An underground detector in a South Dakota mine has failed to find dark matter particles, casting doubt on earlier claims
Earth is not prepared for the threat of hazardous rocks from space, say astronauts who helped formulate the U.N. measures
Physics is all about probing the most fundamental mysteries in nature, so it’s no surprise that physicists have some very basic questions about the universe on their minds.
The recently proposed idea of “black hole firewalls” has physicists questioning some of their most cherished ideas
The latest observations of exploding stars could call into question the cosmological constant explanation of dark energy
Newfound solutions to Maxwell’s electromagnetism equations show light can get as tangled as a sailor’s rope
Hubble observations of the smallest galaxies known help explain why so few of them exist

At the frontiers of high-energy physics, picking “34” is like hitting the lottery
A computer simulation of the universe shows that it may be filled with “defects in spacetime”
Two scientists who predicted how particles gain mass shared the prestigious award, now that Large Hadron Collider experiments have confirmed the theory
The suborbital space firm has audacious plans for orbit, although experts debate their current feasibility
Full disclosure: I cried at a movie about particle physics. And I wasn’t alone. As the film showed footage of the July 4, 2012 announcement of the Higgs boson discovery, I noticed the woman next to me wiping her eyes just as I was doing the same...
