To prep for a supernova, Reina Maruyama, an assistant professor of physics at University of Wisconsin-Madison, is working to ensure that IceCube can handle this once-in-a-lifetime chance to get good data on a stellar explosion.
If something like the 1987 supernova exploded nearby in our galaxy, Maruyama
says, "there would be so many neutrinos, the whole ice would glow.
Since dark matter affects gravity, Maruyama
says it must gather in the sun and the galaxies.

The prototypes are working well enough to justify a larger, more expensive detector, Maruyama
If and when the experiment is replicated in Antarctic Ice, Maruyama
says, "A positive result would be interesting, and a negative result would be interesting.
