LONDON: Scientists have detected vast turbulent waves in the sun's lower atmosphere that at a time spew the energy equivalent of 10 billion nuclear warheads.
Queen's University Belfast (QUB) scientists with researchers from the Universities of Sheffield and California State, have shed some light on why the corona, the region around the sun, has a much higher temperature than its surface - something of a puzzle to scientists.
Their discovery has revealed the existence of a new breed of solar waves, called the Alfven wave, known to transport energy into the corona.
The surface of the sun, known as the photosphere, can reach temperatures of 5,000 degrees Celsius. But the corona has been shown to reach temperatures of over a million degrees Celsius.
The waves have been named after Hannes Alfven who in 1942 received a Nobel Prize for his work in the area.
He theorised the existence of these waves but no hard evidence ever surfaced, until recently, when Mihalis Mathioudakis, a professor and David Jess, both of QUB, made the discovery using the Swedish Solar Telescope in the Canary Islands.
Mathioudakis, leader of the Queen's University Solar Group, said "The solar corona, visible from earth only during a total solar
eclipse, is a very dynamic environment which can erupt suddenly, releasing more energy than 10 billion atomic bombs.
"Our study makes a major advancement in the understanding of how the million-degree corona manages to achieve this feat."
David Jess, from QUB and lead author of the paper said: "Often, waves can be visualised by the rippling of water when a stone is dropped into a pond, or by the motions of a guitar string when plucked," according to a QUB release.
"Alfven waves though cannot be seen so easily. In fact, they are completely invisible to the naked eye. Only by examining the motions of structures and their corresponding velocities in the Sun's turbulent atmosphere could we find, for the first time, the presence of these elusive Alfven waves."

If the Red shift is wrong...most astronomers heads will explode....

Oct 01, 2004 Quasar in Front of Galaxy
October 3, 2003: the big bang was proved wrong. Again. And here is the proof (image above). The galaxy, NGC 7319, is a Seyfert 2, which means it is a galaxy shrouded with such heavy dust clouds that they obscure most of the bright, active nucleus that defines a normal Seyfert galaxy. This galaxy has a redshift of 0.0225. The tiny white spot is a quasar either silhouetted in front of the opaque gas clouds or embedded in the topmost layers of the dust. The redshift of the quasar is 2.114.
Why does this prove the big bang wrong? One of the two major foundations of the big bang is that redshift is proportional to distance. That means the larger the redshift of an object, the farther away it must be. The other major foundation of the big bang is that all redshift is a measure of velocity. Again, the larger the redshift of an object, the faster it is moving away from us. Combined, these two foundations become the expanding universe, which can be traced backwards to the big bang.
Look at the picture again. By the big bang principles, this quasar must be billions of light years farther from us than the galaxy, because its redshift is so much larger. And yet the galaxy is opaque, so the quasar must be near the surface of the dust clouds or even in front of them.

You put waaay too much work into that one.
;)
Pinging others....see post #63.
Then mediate on this.....

Nah, just looking up the BTUs of a kilo ton and then counting a lot of zeros... my calculator handled the rest.
It's been 40 years since I took two years of Russian in college... thanks for the remedial lessons. You are right. However that is what it was called in the west. Perhaps it is more a bad translation by English journalists? It appears the Russians referred to it as "Big Ivan."
Thanks Ernest.
Wow...
that must be approaching the National Debt!
I propose that BTU must be somehow connected with "Barcak Teleprompter Units'.
Cheers!

And that question has been around for a long time regarding the absolute validity of the red shift.
