Is the Sun going to enter a million-degree galactic cloud of interstellar gas?Read about it here.
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.
To clarify: the title is excerpted from Act 1 of Shakespeare's Love's Labour's Lost. The full quote goes: "Light, seeking light, doth light of light beguile; So ere you find where light in darkness lies, Your light grows dark by losing of your eyes." It's a warning against spending too much of your life in scholarly pursuits.
