Ain't no mystery about it

Fountain of Mysterious Dust Found

The universe is not empty. The space between stars and between galaxies is permeated by gas and dust.

In fact our solar system is currently experiencing a cosmic dust storm with at least three times as much dust passing through compared to just a few years ago, owing to a periodic weakening of the sun's magnetic field. And sometime in the next 10,000 years, we'll plow through the G-cloud, a region of dust more dense than the one we're in now.

Astronomers have struggled for a conclusive answer as to where all this dust comes from.

"We not only do not know what the stuff is, but we do not know where it is made or how it gets into space," said Donald York, a professor of astronomy and astrophysics at the University of Chicago.

York and his colleagues have now identified a fountain of dust that appears to be just the sort of culprit they have been looking for.

Cheese it, Topper! I think they're on to you!
