Did you see the film "Contact", starring Jodi Foster?

It was rather a long and drawn out film, about a scientist who has been looking for answers all her life. After her father dies, she puts time and effort into sending radio beams into space.One day she receives a signal back from a star called Vega.
As the countries of the world unite in an effort to decode the transmission, the planet faces the message with equal parts hope and fear, for contained within it are blueprints for a machine of intergalactic travel capable of transporting its passenger to deep space. It could mean the dawning of an astounding new era --or certain Armageddon.
I don't want to spoil the ending for those who may wish to see it, but I found it rather disappointing.
