2002 Kia Spectra No heat

I was driving last night with the heat on, and out of nowhere the heat started blowing out cold air. The battery light came on (this is a brand new battery, not even a month old) and the brake light came on. This morning when I checked the car, there is coolant sprayed all over the right side of the engine. What does this mean? I've had a headgasket go in a car before, but it didn't do the same thing, so hopefully that is not it. Please let me know what I can do. Thanks!
