NASA video: Simply Amazing Solar Prominence Eruption

[Jamie]

Hi,

I just saw this video from NASA:

it shows a solar flare that happened yesterday which shows material
being expelled and then falling back down and splashing on the sun's
surface. The scientist says at 1:25 "it looked like someone kicked a
clog of dirt and it fell back down".. How does this work if the sun is
made out of hydrogen? This hot expelled material must be under extreme
forces to not dissipate in a vacuum before it is able to fall back down
to the sun's surface!

cheers,
Jamie

The Sun's gravitational and magnetic fields. They're quite powerful, you
know.

Hope This Helps!

What do you think keeps the earth's atmosphere from
"dissipating" into the vacuum of space?

Gravity, and since we are near a star, our magnetosphere is a requisite
as well.
