If you’re like me, you’re fretting about what to buy your significant other this coming holiday season. Let it go. We have bigger problems. There’s a humongous star in the constellation Canis Major that’s in its final death throes and could go supernova at any time. VY Canis Majoris, as it is referenced, is the largest star known to science, and is so huge, if it were placed in the center of our Solar System, it would encompass all the space between our Sun and the orbit of the planet Saturn (see diagram). But don’t worry, the unstable red hypergiant is nearly 5000 light-years away, and is being monitored closely (in far-infrared and submillimeter portions of the light spectrum) by the European Space Agency's new space telescope Herschel. Read more here about what's actually going on.
