Sun's Corona Paradox: Temperature Defying Laws of Thermodynamics

    Corona Paradox
AI Thread Summary
The sun's corona reaches temperatures of millions of degrees Celsius, significantly higher than the sun's surface temperature of about 6000 degrees Celsius, which raises questions about thermodynamic laws. This phenomenon is thought to be related to the sun's dynamic magnetic fields, where magnetic 'whips' interact and contribute to heating as they burst into the corona. The process of energy transformation within these magnetic fields complies with thermodynamic principles, suggesting that energy is not lost but rather changes form. The discussion highlights the complexity of coronal heating and the ongoing scientific exploration of this paradox. Understanding these mechanisms is crucial for further insights into solar physics.

Why is the sun's corona temperature around millions of degrees celsius while the sun's surface is about 6000 degrees celsius?

Doesn't that defies the laws of thermodynamics?

Please elaborate on how it defies the laws of thermodynamics. I'm a bit of a newcomer on this topic.
 
This could be due to the moving magnetic fields of the Sun. I've always thought of it as a lot of magnetic 'whips' inside the Sun, bursting out into the corona, and when so many whips come together at that altitude, the temperature rises. Or, when new loops form and collapse, this will raise the temperature as well.

Energy is simply changing forms, which obeys the laws of thermodynamics.

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
