Title:
Lightning on Earth
Explanation:
Nobody knows what causes lightning. It is known that charges [ http://physics.bu.e…] slowly separate in some clouds [ http://ww2010.atmos. uiuc.edu/(Gh)/guides /mtr/cld/cldtyp/home .rxml ] causing rapid electrical discharges [ http://van.hep.uiuc…] (lightning), but how electrical charges [ http://www.sciencem…] get separated in clouds [ http://www.geo.mtu.…] remains a topic of much research. Nevertheless, lightning [ http://wvlightning.…] bolts are common in clouds during rainstorms, and on average 6000 lightning bolts occur between clouds and the Earth every minute. Above [ http://www.astro.um…], several lightning strokes were photographed under a starry sky behind Kitt Peak National Observatory [ http://www.noao.edu…] near Tucson, Arizona [ http://www.state.az…]. Lightning [ http://www.national…] has also been found on the planets Jupiter [ http://antwrp.gsfc.…], Saturn [ http://news.bbc.co.…], and Uranus [ http://www.spacetod…]. NASA [ http://www.nasa.gov/] launched the TRMM mission [ http://trmm.gsfc.na…] in 1997 that continues to measure rainfall and lightning [ http://thunder.msfc…] on planet Earth [ http://antwrp.gsfc.…].
