Billions of years ago, a huge star blasted open and spewed its guts into space. At that energetic moment, the so-called core-collapse supernova formed a debris cloud of brand-new atoms, forged in the heat of its blast. Time passed. The cloud contracted, attracted to itself by its own gravity. A star formed — our sun — surrounded by chunks of rock and gas that formed our planets and other orbiting bodies. Much later, we came along.

That's the basic story of our solar system's birth. And, mostly from watching other supernovas and other star births out in space, scientists know a fair amount about it. But there's still a lot about what happened during the stellar blast that's mysterious. What exotic, energetic particles flared into being in that first, hot flash of the old star's death? How did they shape the atoms and molecules that formed humans? How much time passed between the star's death and rebirth as our sun?

In a new paper published yesterday (Sept. 4) in the journal Physic

Jupiter is strange for a number of reasons. It’s the biggest planet in our Solar System, of course. It harbors perhaps the most intense radiation environments. And, according to a new study, it has a magnetic field unlike that of any other known planet.

NASA’s Juno orbiter, a basketball court-sized spacecraft, is observing the gas giant as it circles the planet at varying distances. Scientists recently mapped Jupiter’s magnetic field at four depths, and noticed a strange hemispheric dichotomy: The northern hemisphere’s magnetic field was nothing like the southern hemisphere’s.

Mining resources from asteroids may sound like the stuff of science fiction, but it could be well on its way to becoming science fact. What will be mined? Why do we want this? And who are the big names to watch out for? Check out our beginner's guide to all things space rock-drilling.
A recent contest challenged participants to create utopian designs of future human Mars settlements, and their creations are stunning.
