Starship Asterisk*

Interesting collection of links with this APOD description - our sun, even though it has occasional outbursts, so far certainly isn't the drama queen that it might become as it reaches menopause .....

I noticed something that impacted me way back in high school (1955-1959) - in our physics class, we were taught the subject using the centigrade scale - I noticed that the centigrade scale was officially changed to the celsius scale in 1948 by the 9th General Conference on Weights and Measures (CGPM). Shame, shame on my teachers!!!

Also, of interest, when I was listening to the Singing Sun audio, both my dog (asleep by my feet) and my cat (asleep on the table by the laptop) woke up - the cat kept nosing around the speaker on the computer; the dog raised his head, looked at me and kept "wincing" until I stopped the "music" ....

Then call it Ra, Aton or Tonatiuh. :mrgreen:
Although Tonatiuh is closer for me and his is represented in Aztec calendar.

Science@NASA: Spacequakes Rumble Near Earth

In the last mail I received from NASA describes the following phenomenon is the address in Spanish http://ciencia.nasa.gov/headlines/y2010/27jul_spacequakes.htm

"Now I know," says David Sibeck, the scientist who is a member of the THEMIS project at the Goddard Space Flight Center. "Plasma jets cause tremors space."

According to the project THEMIS, the jets crash into the geomagnetic field about 30,000 km above the Earth Ecuador. The impact causes a rebound process, in which the plasma actually bounces up and down along the magnetic field that is reverberating. Researchers call it "push repetitive flow." It's like a tennis ball bouncing upward succession of decreasing amplitude are due to energy dissipated in the carpet.

So old Sol is active again. :) Don't forget to watch the video and listen to the song. 8-)
