virtualsky.lco.globalVirtualSky - Browser-based Planetarium

application (c) 2010 Stuart Lowe (Las Cumbras Observatory Global Telescope)Fork Me on GitHub a browser-based planetarium from Las Cumbres Observatory that lets you see what is visible in the sky from any location on Earth. It can be customized and included on your own website , blog etc. It is provided freely for educational and non-profit use.

Instructions for embedding The easiest way to include on your website is to use the custom form to create an embed link (uses an iframe ). Sometimes an iframe just doesn’t give you the flexibility you need (or you might want to include it in an offline page during a public talk). In that case you could download a copy of the source from GitHub and include in your page using Javascript. You will need to include the following code block in the head of your page: ![if lt IE 9]script src="excanvas.min.js"/script![endif] script src="jquery-1.10.0.min.js"/script script src="virtualsky.min.js" type="text/javascript"/script script $(document).ready(function() { var planetarium = $.virtualsky({ id: ’starmap1’ }); }); /script Make sure the scripts point to the correct locations for the Javascript files. In the body you need to include the DOM element you’ve referenced by ID: div style="width:400px;height:400px;"/div The result is: That is a version of with all the default options. However, one of the great things about is that it can be customised. Here are some examples to give you some ideas: A stereo projection set for Santa Barbara’s lat/long: $(document).ready(function() { var planetarium = $.virtualsky({ id: ’starmap’, projection: ’stereo’, latitude: 34.4326, longitude: -119.86286 }); }); div style="width:100%;height:500px;"/div A lambert projection, with constellations shown, no keyboard control and a black-on-white view. It is based in Manchester,UK and facing north: $(document).ready(function() { var planetarium = $.virtualsky({ id: ’starmap’, projection: ’lambert’, mouse: true, keyboard: false, az: 0, negative: true, constellations: true, latitude: 53.5, longitude: -2.5 }); }); div style="width:500px;height:300px;"/div A stereo projection with no keyboard or mouse input and with a Galactic grid and the Meridian line displayed. The view is facing south east from Hill Valley, California at 1:21 am on October 25, 1985. $(document).ready(function() { var planetarium = $.virtualsky({ id: ’starmap’, projection: ’stereo’, keyboard: false, mouse: false, az: 135, meridian: true, latitude: 38.25, longitude: -122.6, clock: new Date("October 25, 1985 01:21:00"), gridlines_gal: true }); }); div style="width:650px;height:300px;"/div A mollweide projection with with star labels drawn and the ground blocking half the sky. $(document).ready(function() { var planetarium = $.virtualsky({ id: ’starmap’, projection: ’mollweide’, showstarlabels: true, ground: true }); }); div style="width:920px;height:460px;"/div A default view with a stereo projection, constellation lines and two manually specified constellation boundaries (note that RA/Dec for boundaries are assumed to be in B1875). $(document).ready(function() { var planetarium = $.virtualsky({ id: ’starmap’, az: 225, projection: ’stereo’, constellations: true, constellationboundaries: true, boundaries: [ ["And",343,34.5,343,52.5,350,52.5,350,50,353.75,50,353.75,48,2.5,48,2.5,46,13,46,13,48,16.75,48,16.75,50,20.5,50,25,50,25,47,30.625,47,30.625,50.5,37.75,50.5,37.75,36.75,30,36.75,30,35,21.125,35,21.125,33,10.75,33,10.75,23.75,12.75,23.75,12.75,21,2.125,21,2.125,22,1,22,1,28,0,28,0,31.33333,356.25,31.33333,356.25,32.08333,352.5,32.08333,352.5,34.5,343,34.5], ["Ori",69.25,0,69.25,15.5,74.5,15.5,74.5,16,80,16,80,15.5,84,15.5,84,12.5,86.5,12.5,86.5,18,85.5,18,85.5,22.83333,88.25,22.83333,88.25,21.5,93.25,21.5,93.25,17.5,94.625,17.5,94.625,12,94.625,10,93.625,10,93.625,0,93.625,-4,87.5,-4,87.5,-11,76.25,-11,76.25,-4,70,-4,70,0,69.25,0] ], clock:new Date("July 17, 2013 18:39:00 GMT") });
