Star Collisions Are Popular
News story originally written on June 12, 2000

Scientists know that galaxies sometimes collide together, but they didn't think that stars in the same galaxy suffered the same fate. It turns out that they may be wrong. New evidence shows that stars within globular clusters collide together on a regular basis.

You might say they need their own space. Young stars are created in a dense area. It's only a matter of time before it gets too crowded, and stars start combining to form larger, hotter and even younger stars. Scientists say these events even occur in our own Milky Way.
