Editing Jupiter (section)

==== Radiotelescope research ====
In 1955, Bernard Burke and [[Kenneth Franklin]] discovered that Jupiter emits bursts of radio waves at a frequency of 22.2&nbsp;MHz.<ref name="elkins-tanton"/>{{rp|36}} The period of these bursts matched the rotation of the planet, and they used this information to determine a more precise value for Jupiter's rotation rate. Radio bursts from Jupiter were found to come in two forms: long bursts (or L-bursts) lasting up to several seconds, and short bursts (or S-bursts) lasting less than a hundredth of a second.<ref>{{cite web |last=Weintraub |first=Rachel A. |date=September 26, 2005 |url=http://www.nasa.gov/vision/universe/solarsystem/radio_jupiter.html |title=How One Night in a Field Changed Astronomy |publisher=NASA |access-date=February 18, 2007 |archive-date=July 3, 2011 |archive-url=https://web.archive.org/web/20110703080812/http://www.nasa.gov/vision/universe/solarsystem/radio_jupiter.html |url-status=dead }}</ref>

Scientists have discovered three forms of radio signals transmitted from Jupiter:
* Decametric radio bursts (with a wavelength of tens of metres) vary with the rotation of Jupiter, and are influenced by the interaction of Io with Jupiter's magnetic field.<ref>{{cite web |last=Garcia |first=Leonard N |url=http://radiojove.gsfc.nasa.gov/library/sci_briefs/decametric.htm |title=The Jovian Decametric Radio Emission |publisher=NASA |access-date=February 18, 2007 |archive-date=March 2, 2012 |archive-url=https://web.archive.org/web/20120302222737/http://radiojove.gsfc.nasa.gov/library/sci_briefs/decametric.htm |url-status=live }}</ref>
* Decimetric radio emission (with wavelengths measured in centimetres) was first observed by [[Frank Drake]] and Hein Hvatum in 1959.<ref name="elkins-tanton"/>{{rp|36}} The origin of this signal is a torus-shaped belt around Jupiter's equator, which generates [[cyclotron radiation]] from electrons that are accelerated in Jupiter's magnetic field.<ref>{{cite journal | last1=Klein | first1=M.

* [[Thermal radiation]] is produced by heat in the atmosphere of Jupiter.<ref name="elkins-tanton"/>{{rp|43}}
