As plasma is ejected from the sun's surface, its temperature skyrockets--and so far physicists have not been able to explain whyRebecca Boyle
Why does the plasma tail of a comet always point away from the sun? Comets: You're probably familiar with the concept of comets, but what you might not know is what makes a comet different from an asteroid. It's not just that comets have a tail that makes them different from...
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...
What is the most common chemical element in the universe?How are all the other chemical elements formed?Define the terms:Galaxy,nebula,black hole,supernova,comet,asteroid,meteorite(这题必须用英文答)How and when is earth thought to have formed?Do the magnetic poles of the earth change?How do...
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...
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...
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, ...
At this point, the stream of charged particles emitted by the sun, known as the solar wind, becomes too weak to repel the oncoming stream of radiation from stars and other cosmic entities in the Milky Way. "Because the plasma inside the heliopause is of solar origin, and the plasma out...
For momentum to be exchanged between two bodies, they have to possess a net difference in momentum to begin with. The Earth and its atmosphere have the same momentum on the whole. Now there is low density plasma in the solar system primarily generated by the Sun. So yes that creates drag...
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 ...
