exploded stars. In particular you will use information on the Crab
Nebula (the 1054 aD supernova registered by Chinese astronomers) to
derive its distance: an example of how some very important information
may be gained from very simple arguments and geometry.</description><referenceURL>http://wwwas.oats.inaf.it/aidawp5/eng_download.html</referenceURL><contentLevel>General</contentLevel><relationship><relationshipType>Cites</relationshipType><relatedResource>The ALADIN image server</relatedResource><relatedResource altIdentifier="ascl:1112.019">Aladin</relatedResource></relationship></content><rights rightsURI="https://spdx.org/licenses/CC-BY-4.0.html">The AIDA M1 tutorial is licensed under the `Creative Commons Attribution 4.0 License &lt;http://creativecommons.org/licenses/by/4.0/&gt;`_
