Imagine a planet-sized bundle of intense, magnetic field lines; that's exactly what a sunspot is. Now, researchers have taken a closer look at how these events drive massive, explosive reactions.
NASA has revealed its five science selections for refinement during the next year as a first step in choosing one or two missions for flight opportunities as early as 2020.
Preparing for long-distance space travel is going to be difficult for the human body.
We may be learning better ways to hunt for life on Mars.
Could asteroids be the moon's main "water supply?"
Hurricane Joaquin is barreling toward the United States. Now, NASA satellites are gathering a bit more information on the storm so that we can be a bit more prepared for when it hits.
NASA's Dawn spacecraft is revealing a bit more about the dwarf planet, Ceres.
What causes Martian megafloods? Scientists may have a new hypothesis.
It turns out that Rosetta's comet may not have always been just one object. Researchers have found that two comets collided at low speed in the early solar system to create the strangely-shaped Comet 67P/Churyumov-Gerasimenko.
Earth-like plants may actually have magnetic fields, which may aid chances for life. Scientists have discovered that these planets orbiting close to small stars have magnetic fields that protect them from stellar radiation and help maintain safe surface conditions.
ESA's Rosetta spacecraft has detected argon on the comet 67P/Churyumov-Gerasimenko for the first time.
