Latest Alfvén wave Stories
Many areas of scientific research -- Earth's weather, ocean currents, the outpouring of magnetic energy from the sun -- require mapping out the large scale features of a complex system and its intricate details simultaneously.
We all know that turbulence exists on Earth, but does it really exist in outer space? And if it does, how would you prove it?
A new study sheds light on why the Sun's outer atmosphere, or corona, is more than 20 times hotter than its surface.
Powerful magnetic waves have been confirmed for the first time as major players in the process that makes the sun's atmosphere strangely hundreds of times hotter than its already superhot surface.
As you move away from the solar surface, into the sun's outer atmosphere, the corona, it actually gets a lot hotter before it cools off. The solar surface is about 10,000 degrees Fahrenheit, while temperatures in the corona soar to millions of degrees.
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
