For nearly 70 years, astronomers have struggled to explain "dark matter," which accounts for nearly all the matter in the universe. Although they can't see it, astronomers know it's there, because its gravity affects the matter astronomers do see.

Now, a research team claims it has found direct evidence of a portion of the dark matter affecting the Milky Way.

What have they found? A sizable number of dying, once-sunlike stars lurking in the vast expanse ...
