APOD: Persistent Saturnian Auroras (2014 Jun 22) Image Credit: J. Clarke (Boston U.) & Z. Levay (STScI), ESA, NASA http://apod.nasa.gov/apod/ap140622.html Explanation: Are Saturn's auroras like Earth's? To help answer this question, the Hubble Space Telescope and the Cassini spacecraft monitored Saturn's South Pole simultaneously as Cassini closed in on the gas giant in January 2004. Hubble snapped images in ultraviolet light, while Cassini recorded radio emissions and monitored the solar wind. Like on Earth, Saturn's auroras make total or partial rings around magnetic poles. Unlike on Earth, however, Saturn's auroras persist for days, as opposed to only minutes on Earth. Although surely created by charged particles entering the atmosphere, Saturn's auroras also appear to be more closely modulated by the solar wind than either Earth's or Jupiter's auroras. The above sequence shows three Hubble images of Saturn each taken two days apart. http://www.stsci.edu/ http://www.bu.edu/dbin/astronomy/ http://hubblesite.org/news/2005/06 http://spacetelescope.org/news/heic0504/ http://saturn.jpl.nasa.gov/ http://www.nasa.gov/hubble Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140622 #APOD

FCC proposal would fund WiFi networks in schools

The FCC's E-rate program has been funding classroom internet access for a while, but it's focused on wired connections; that's a bit short-sighted in an era where many laptops and tablets are WiFi-only. Agency officials are keenly aware of this need to catch up, as they've proposed a plan that uses …
