The two galaxies are racing toward each other at 250,000 mph and will collide less than 5 billion years from now. Luckily, astronomers predict that our solar system will remain intact as these two ...

"If two galaxies actually collide with each other the stars basically pass right between each other, and the chance of two stars directly hitting each other is really, really small," said van der ...

If you see a pair of bright eyes in the inky depths of space, you’re seeing what a team of astronomers spied last year—a rare formation created by the grazing collision of two spiral galaxies.
