Does the sun have a heartbeat that is veeeeeeeeery slow and the result is sunspots?
“Like blood pulsing in an artery, newly discovered currents of gas beat deep inside the Sun, speeding and slackening every 16 months. The solar “heartbeat” throbs in the same region of the Sun suspected of driving the 11-year cycle of solar eruptions, during which the Sun goes from stormy to quiet and back again. Scientists are hopeful that this pulse can help them unravel the origin and operation of the solar cycle.” http://science.nasa.gov/science-news/sci… “the number of sunspots visible on the sun waxes and wanes with an approximate 11-year cycle.” http://solarscience.msfc.nasa.gov/Sunspo… http://solarscience.msfc.nasa.gov/images… If NASA refers to it as a heartbeat its good enough for this symbol guy.
