As plasma is ejected from the sun's surface, its temperature skyrockets--and so far physicists have not been able to explain whyRebecca Boyle
Are you saying that EM interactions are a key ingredient in, for instance, the internal dynamics of our Solar System? If you're asking about the dynamics of the planets around the Sun, then no. However, for ions (ie. a plasma), and small charged particles such a dust and grain...
A NASA image of plasma bursting from the sun. Plasma—a hot soup of atoms with free-moving electrons and ions—is the most abundant form of matter in the universe, found throughout our solar system in the sun and other planetary bodies. A new study from University of Rochester researchers ...
The Sun's fire comes from a nuclear reaction burning hydrogen. (Image credit: NASA.) For millennia, people have looked up to the sky and wondered about celestial bodies. The sparkling stars and fiery sun hold mystery and wonder. To astronomers, the sun is just another dying star, but to...
Composed of 8 planets, 1 sun, and thousands of asteroids, comets, moons, and other small rocks, our solar system is the only place so far that we have discovered life. The Sun makes up about 99.8% of the mass of the solar system and is what provides all the energy to the planets...
How is energy from the Sun distributed around Earth? (a) If nuclear fusion is the result of two hydrogen atoms glomming onto each other to form plasma with super heat, forming a helium atom -- where do the two neutrons that a helium atom requires come from? (b) How come there is a...
With a sunspot, you have a magnetic field and it basically freezes that convection cell and causes the sun to cool down. It looks black because the cool stuff rises and gets stuck there. The plasma is a little cooler than the plasma around it. It’s still quite hot. It’s not like ...
Because of their great distance from Earth, however, the chorus waves in the latest results “sort of remove the curvature element,” says Daniel Ratliff, a plasma physicist at Northumbria University in England, who was not part of the study. “And yet you still get these very clear, ...
Eventually, the plasma becomes so hot that the sun's gravity can no longer hold it down so it is hurled into space as the solar wind, dragging the sun's magnetic field along with it, according to NASA JPL. Did you know? The solar wind transports a million tons of matter into space...
Bear Solar Observatory (BBSO) have captured the first high-resolution images of magnetic fields and plasma flows originating deep below the Sun's surface, tracing the evolution of sunspots and magnetic flux ropes through the chromosphere before their dramatic appearance in the corona as flaring loops...
