Giant Waves Nearly Half a Million Miles Across Seen on the Sun for the First Time

"Solar Rossby waves are gigantic in size, with wavelengths comparable to the solar radius," study co-author Laurent Gizon, of the Max Planck Institute for Solar System Research, said in a statement. (The average radius of the sun is a whopping 432,450 miles, or 696,000 kilometers.)

Even so, these waves move very slowly, with shallow troughs and peaks, so they aren't always easy to detect, especially amid the other swirls and disturbances on a body as lively as the sun.

Researchers from the Max Planck Institute for Solar System Research, the University of Göttingen (both in Germany), New York University Abu Dhabi and Stanford University analyzed data from the SDO's Helioseismic and Magnetic Imager instrument. They focused on bubble-like granules on the visible surface of the sun, called the photosphere. These granules — each about 600 miles (1,000 kilometers) across, according to NASA — are the peak of convection cells, where heated material from the sun's interior pops up toward the surface, spreads out and then cools, sinking down along the dark lines that divide the granules. According to NASA, these granules are hyperintense, with materials bubbling up as fast as 15,000 mph (more than 24,000 km/h).

The movements of these granules revealed underlying Rossby waves, the researchers reported May 7 in the journal Nature Astronomy.

The researchers found that the waves occur deep below the surface of the sun, about 12,400 miles (20,000 km) in its interior.

They estimate that the waves are responsible for about half of the sun's kinetic energy, making them key to understanding the star's internal dynamics.

"All in all...large-scale waves of vorticity on the sun that move in the direction opposite to rotation."

Clearly the sun is a victim of man made global warming or cooling or climate change.

Can those waves be caused by Chuck Berry upsetting the energy of the universe?

Got nothin to do with waves, but it's also the 50th anniversary of Corvette Summer!

Global warming scientists will declare the sun to be transgender!

I liked it. The car too.



But one thing bothers me. Remember when he stacked all that stuff on top the oil drum to make it look like he climbed to the window and escaped, but then hid in the oil drum instead? How did he get in there with all the stuff stacked on top?

He used the force of course, he learned that in Star Wars.

As a longtime Freeper I find it highly offensive that lofty achievements worthy of the name Max Planck are now subjected in this once august forum to petty mockery and derision.

I am prepared to call a meeting to address this chagrin.

In 1889 he was named the successor to Kirchhoff’s position at the Friedrich-Wilhelms-Universität in Berlin[9] – presumably thanks to Helmholtz’s intercession – and by 1892 became a full professor. In 1907 Planck was offered Boltzmann’s position in Vienna, but turned it down to stay in Berlin. During 1909, as a University of Berlin professor, he was invited to become the Ernest Kempton Adams Lecturer in Theoretical Physics at Columbia University in New York City. A series of his lectures were translated and co-published by Columbia University professor A. P. Wills.[10] He retired from Berlin on 10 January 1926,[11] and was succeeded by Erwin Schrödinger.[12]”

Impressive environment....

Yes and no, Paladin. Some of that guy's friends were real charlatans. My Dad's Dad, for instance, was the family vet to this wonky guy "Schrodinger." Well at some point the guy calls him - my grandfather - in the middle of the night and he - my Pops - rushes over in a big Packard we had at the time, which frankly is irrelevant. Well, he gets there and the cat - it's a cat - is dead. The analysis is done, whatever... The cat is dead. Schrodinger says "take him away." So we do. Now that's disposal, which is expensive. Come time to pay the bill, the guy balks. "MEIN MUSHIE IST NACHT DEAD," and on and on. (I don't speak that language.) But that's the kind of crap you deal with with these people.

I need to head over to the Dead Sea or perhaps the Great Salt Lake or the closed salt mines of Detroit...for at least a large grain...

Surf’s up dude! Gonna need about a 1000 Sunscreen rated cream, however. And fiberglass boards are definitely out.

At least you can cook your own hotdogs and boogieboard at the same time.

Yeah you're right I miss typed , it's the fortieth anniversary, to bad there still isn't a way to correct posts. And aside from being as teen boy fantasy movie, yeah it's crap, shlock, barely 'B' fare. I can't recall even a handfull of movies that Hamill had a decent presence in.

But that's my opinion, no need to get all riled up if you liked it, I'm sure that there are lots of movies you like that I think are crap and vice a versa. It's not like we're democrats and have to be mindless robots.
