According to science, there&#8217;s a whole world of nuance.<\/p>\n<p> &#8220;What is counterintuitive is that we do see very powerful jets of material that are actually expelled from them as well,&#8221; Natarajan says. <\/p>\n<p>These jets that shoot out from supermassive black holes, like the one at the center of the Milky Way galaxy, are sometimes millions of light years long. They carry huge amounts of energy and radiation.<\/p>\n<aside id=\"ad-backstage-wrap\" class=\"ad-wrap backstage\" aria-label=\"advertisement\">\n<\/aside>\n<p>&#8220;One should think of them perhaps in the same way as one thinks about nuclear power,&#8221; says Roger Blandford, an astrophysicist and professor at Stanford University. &#8220;Of course, they can be famously destructive, but also it can be a source of power in a nuclear reactor.&#8221; <\/p>\n<p>Blandford and his colleague Roman Znajek are known for coming up with an explanation for how these jets get their energy, known as the Blandford-Znajek process. Telescope images from the last few years have supported their hypothesis.<\/p>\n<p><strong>If you liked this episode you might want to hear more about <\/strong><strong>supermassive black holes,<\/strong><strong> <\/strong><strong>what it might be like to fall into a black hole<\/strong><strong> or <\/strong><strong>lessons we can learn from black holes<\/strong><strong>.  <\/strong><\/p>\n<p><em>Got other cosmic curiosities?
