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
The first discovery of a rocky, watery object beyond our solar system shows how planets might get their oceans
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.
Although the life-threatening situation Gravity depicts is fictional, the new film faithfully captures the beauty of orbit, says a former space station crew member
The Fermi Gamma-Ray Space Telescope team is considering a new observing strategy that would focus on the center of the galaxy
NASA calls for rover instrument proposals, but some resent the space lost to storage of samples for retrieval by an unspecified future mission
Friction is both the boon and the bane of our everyday lives. It’s the force that drags against your car’s tires, making you use more gas to keep going.
Although a broken reaction wheel on NASA's Kepler spacecraft is bad news for its primary exoplanet-hunting mission, the glitch could be a boon for the study of stellar physics
Despite dozens of measurements over more than 200 years, we still don’t know how strong gravity is
After much debate over the murky boundary of interstellar space, a solar eruption gives scientists the evidence to say Voyager 1 has finally crossed it
The big bang should have distributed matter evenly throughout the universe. So why is there a big dense spot?
