Galaxy far, far away set to crash into us in 4 billion years6/1/2012
Look out, there's a giant galaxy headed our way! Using the Hubble Space Telescope, astronomers are predicting when our solar system will collide with Andromeda, currently a galaxy that's far, far away. The Milky Way and its neighbor will crash into each other in just 4 billion years, but 2 billion years after that, they'll merge into one big happy galaxy. The collision will look spectacular to humans on Earth, assuming we still exist. Researcher Roeland van der Marel says the sun will be too hot for human survival by then, but "if we find a smart way to use solar energy and turn it into air conditioning, we may still be able to live on this planet."
If the Milky Way and Andromeda merge, what should the new galaxy be called?
