AS if we didn't have enough to worry about.

Is the Sun going to enter a million-degree galactic cloud of interstellar gas?

A group of scientists are suggesting that the Ribbon of enhanced emissions of Energetic Neutral Atoms(ENA) discovered last year by the NASA Small Explorer satellite IBEX could be explained by a geometric effect coming up because of approach of the Sun to the boundary between the Local Cloud of interstellar gas and another cloud of a very hot gas called the Local Bubble.

If their hypothesis is correct, IBEX is catching matter from a hot neighboring interstellar cloud, which the Sun might enter in a hundred years.
