Nasa's Voyager 2 probe 'leaves the Solar System'
My all-time favorite graph is the plot of incident solar particles on Voyager 1 in 2012 [0][1]. That to me is the perfect image of scientific thinking. "We anticipate that the probe will enter interstellar space and see a significant drop in the number of incident solar particles." And then it happens, clear as day.<p>I teach high school math and science, and I have shown this graph to students every year. Many students get what this really means. They suddenly understand how far Voyager is from us, and how small and isolated our solar system really is in the universe.<p>Now it will be fun to show them the same graph from Voyager 2 [2][3]!<p>[0] <a href="https://3c1703fe8d.site.internapcdn.net/newman/gfx/news/hires/2012/jyguyg.jpg" rel="nofollow">https://3c1703fe8d.site.internapcdn.net/newman/gfx/news/hire...</a><p>[1] <a href="https://phys.org/news/2012-10-voyager-left-solar.html" rel="nofollow">https://phys.org/news/2012-10-voyager-left-solar.html</a><p>[2] <a href="http://earth-chronicles.com/wp-content/uploads/2018/11/voyazh.png" rel="nofollow">http://earth-chronicles.com/wp-content/uploads/2018/11/voyaz...</a><p>[3] <a href="http://earth-chronicles.com/space/voyager-2-is-even-closer-to-the-border-of-the-solar-system.html" rel="nofollow">http://earth-chronicles.com/space/voyager-2-is-even-closer-t...</a>
