California, Santa Barbara / LCOGT) ] Title Image: Kepler's Supernova Remnant - Chandra (X-ray) / Hubble (Optical) / Spitzer (IR) Explanation: To create a sonata from supernovae, first you have to find the supernovae. To do that composers Alex Parker and Melissa Graham relied on the Canada France Hawaii Telescope (CFHT) Legacy Survey data of four deep fields on the sky monitored from April 2003 through August 2006, adopting 241 Type Ia supernovae. Enchanting to cosmologists, Type Ia supernovae are thermonuclear explosions that destroy white dwarf stars. Then, they gave each supernova a note to play, the volume of the note determined by the distance to the supernova. Fainter, more distant supernovae play quieter notes. Each note's pitch was based on a stretch factor measured by how fast the supernova brightens and fades over time relative to a standard time history. Higher stretch factors play higher notes in pitches drawn from the illustrated Phrygian dominant scale. Of course, each supernova note is played on an instrument. Supernovae in massive galaxies were assigned to a stand-up bass, while supernovae in less massive galaxies played their note on a grand piano.

Interesting.
The Dominant Phrygian scale is very charactarist of Hebrew Worship and Jewish Klezmer Music.

Hence, it has earned the moniker: “The Jewish Scale”.

Oh, okay, I guess I’d misheard it, that does make more sense. ;’)

I’ll make a note of it.

The Histories
by Herodotus
tr by George Rawlinson
Book II -- Euterpe

Now the Egyptians, before the reign of their king Psammetichus, believed themselves to be the most ancient of mankind. Since Psammetichus, however, made an attempt to discover who were actually the primitive race, they have been of opinion that while they surpass all other nations, the Phrygians surpass them in antiquity. This king, finding it impossible to make out by dint of inquiry what men were the most ancient, contrived the following method of discovery: He took two children of the common sort, and gave them over to a herdsman to bring up at his folds, strictly charging him to let no one utter a word in their presence, but to keep them in a sequestered cottage, and from time to time introduce goats to their apartment, see that they got their fill of milk, and in all other respects look after them. His object herein was to know, after the indistinct babblings of infancy were over, what word they would first articulate. It happened as he had anticipated. The herdsman obeyed his orders for two years, and at the end of that time, on his one day opening the door of their room and going in, the children both ran up to him with outstretched arms, and distinctly said "Becos." When this first happened the herdsman took no notice; but afterwards when he observed, on coming often to see after them, that the word was constantly in their mouths, he informed his lord, and by his command brought the children into his presence. Psammetichus then himself heard them say the word, upon which he proceeded to make inquiry what people there was who called anything "becos," and hereupon he learnt that "becos" was the Phrygian name for bread. In consideration of this circumstance the Egyptians yielded their claims, and admitted the greater antiquity of the Phrygians.

They sure do play a nice scale! A very OLD one!
