Physicists have long believed that magnets can exist with only one pole as opposed to one with a north and south pole. In a new study, they were able to create a magnetic field that contained only monopoles.
A controversial 2007 study which found that a comet wiped out megafauna around 12,000 years ago is not implausible, according to a new study which recreated the earlier study. The Younger Dryas Boundary hypothesis says that nanodiamonds found along Bull Creek in Oklahoma were deposited there by a comet collision.
New research explains how large galaxies — formed by the collision of small, compact "baby galaxies" — could have existed even in the early years of the universe.
Mechanical problems aboard the Jade Rabbit lunar rover threaten to foil one of China's most celebrated scientific achievements. The state news agency, which reported the news, was vague about details, but others have suggested the problem is with the vehicle's solar panels.
Since there were major earthquakes along the Mississippi River 200 years ago, scientists have debated whether subsequent tremors were aftershocks, or tension building up. Now, a new study suggests there's a risk of another earthquake, though it can't predict when it will happen.
A leading developer of privately-owned spacecrafts, which could soon replace the shuttle program, announced this week that it will test its Dream Chaser space plane on Nov. 1, 2016.
Stephen Hawking's solution to a black hole paradox tosses out everything that was once awesome about black holes: their ability to suck up matter and never let it out, including light. Under the new model, Hawking suggests that matter comes and goes from black holes more or less as it pleases.
A team of University of London students accidentally spotted a once-in-a-lifetime astronomical event while taking a telescope workshop on January 21: a supernova, or exploding star in Messier 82.
In May 2014, the Rosetta spacecraft is expected to make a rendezvous with Comet 67P/Churyumov-Gerasimenko. But in order to do so, first Rosetta has to wake up.
A rock has appeared in front of the Mars rover Opportunity, and NASA isn't sure where it came from. In two photos of the same spot on Mars, taken 12 Martian days apart, a rock appears suddenly in the later photo. NASA Mars Exploration Rover lead scientist Steve Squyres suspects the rover may have shifted around, kicking the rock in front of Opportunity's camera.
The black hole at the center of our galaxy, the Milky Way, is expecting a visitor about as massive as the earth sometime this spring. It's a gas cloud, and scientists can only wait to see what will happen as it passes by.
