When it comes to science--and Science--there are some breakthroughs that stand above the rest. Now, the journal has released the top-10 list of scientific breakthroughs for 2014. What made the list? That's a good question.
Scientists have solved a long-standing mystery in space. They've uncovered the origin of the "theta aurora," an aurora that occurs at startlingly high latitudes on Earth.
Although the Kepler spacecraft's primary mission came to an end when the second of four reaction wheels used to stabilize the spacecraft failed, scientists have come up with an ingenious strategy to control Kepler and use it in a new mission.
