The spinning vortex of <a href="https://www.windows2universe.org/saturn/saturn.html">Saturn</a>'s north polar storm resembles a giant deep red rose surrounded by green foliage in this false-color <a href="http://www.nasa.gov/mission_pages/cassini/multimedia/pia14944.html">image</a> from NASA's <a href="https://www.windows2universe.org/missions/cassini.html">Cassini spacecraft</a>. The eye is 2,000 kilometers across with cloud speeds as fast as 150 meters per second.
It is not known how long this newly discovered north-polar <a href="https://www.windows2universe.org/earth/Atmosphere/hurricane/hurricane.html">hurricane</a> has been active.
The view was acquired at a distance of approximately 419,000 kilometers from Saturn.<p><small><em>NASA/JPL-Caltech/SSI</em></small></p>There are over 900 <a href="/php/tour_test_sqli.php?page=/the_universe/uts/megalith.html">rings of stone</a> located in the British Isles. The most famous of these stone rings is of course, <a href="/php/tour_test_sqli.php?page=/the_universe/uts/stonehenge.html">Stonehenge</a>.    The stones of Stonehenge were put in place between 3,000 B.C and 2,000 B.C. by neolithic people.Some speculate that the site was built as a temple of worship of the ancient Earth deities. Some say it was used as an <a href="/php/tour_test_sqli.php?page=/the_universe/uts/stonehenge_astro.html">astronomical observatory</a> of sorts. Still others say it was a burial ground.<p><small><em>  Image courtesy of Corel Photography.</em></small></p>According to <a href="http://www.jpl.nasa.gov/news/news.php?release=2013-277">NASA scientists</a>, the Voyager 1 spacecraft entered interstellar space in August 2012, becoming the first spacecraft to leave the <a href="/php/tour_test_sqli.php?page=/our_solar_system/solar_system.html">solar system</a>. The space probe is about 19 billion km from the <a href="/php/tour_test_sqli.php?page=/sun/sun.html">Sun</a>.  <a href="/php/tour_test_sqli.php?page=/space_missions/voyager.html">Voyager 1 and 2</a> were launched in 1977 on a <a href="/php/tour_test_sqli.php?page=/space_missions/voyager.html">mission</a> that flew them both by <a href="/php/tour_test_sqli.php?page=/jupiter/jupiter.html">Jupiter</a> and <a href="/php/tour_test_sqli.php?page=/saturn/saturn.html">Saturn</a>, with Voyager 2 continuing to <a href="/php/tour_test_sqli.php?page=/uranus/uranus.html">Uranus</a> and <a href="/php/tour_test_sqli.php?page=/neptune/neptune.html">Neptune</a>. Voyager 2 is the longest continuously operated spacecraft. It is about 15 billion km away from the <a href="/php/tour_test_sqli.php?page=/sun/sun.html">Sun</a>.<p><small><em>Image courtesy of NASA</em></small></p>The massive 9.0 magnitude <a href="/php/tour_test_sqli.php?page=/earth/geology/quake_1.html">earthquake</a> off of Honshu, Japan on <a href="/php/tour_test_sqli.php?page=/headline_universe/march112011earthquaketsunami.html">11 March 2011</a> generated a <a href="/php/tour_test_sqli.php?page=/earth/tsunami1.html">tsunami</a> that exceeded 10 meters on the coast near the epicenter.  This image shows model projections for the tsunami wave height in cm which are in good agreement with the observed waves. Our thoughts and prayers are with those who were lost, and their families, as we remember this event.<p><small><em><a href="http://blogs.agu.org/wildwildscience/files/2011/03/680_20110311-TsunamiWaveHeight.jpg">NOAA Tsunami Wave Height Projections image</a></em></small></p>A near-Earth <a href="/php/tour_test_sqli.php?page=/our_solar_system/asteroids.html">asteroid</a> - named 2012 DA14 by astronomers  passed within 17,200 miles from Earth on February 15, 2013. On closest approach at about 1:25 p.m. CST on February 15, although it was within the orbit of the <a href="/php/tour_test_sqli.php?page=/earth/moons_and_rings.html">Moon</a> and even geosynchronous <a href="/php/tour_test_sqli.php?page=/space_missions/satellites.html">satellites</a>, it didn't strike Earth!

The power outage experienced by residents in New York City on 10/30/2012 due to Hurricane Sandy demonstrates the interconnectedness of our society, and the power of the Earth system.  Every person should have an understanding of how the Earth system works so they can live better lives, protect those they love, and make wise choices.
