Alien Contact

For the first time in human history, humanity has done something that only been dreamed of before: discover intelligent and sentient alien life. While traveling the cosmos, your crew has stumbled upon an alien starship. After some deliberation, your crew has decided to attempt to contact the alien ship, hoping to establish contact between races. However, contact with an alien race is a delicate thing, so after long deliberation they have decided to appoint you as ambassador to attempt to establish contact with the aliens, hoping that your Universal Translation Systems will be able to decode their language, allowing communication. Not knowing anything about them or their culture you decide to hail the ship, and when the video feed comes through, you find three strange looking creatures with gray skin and huge black eyes staring back at you (as in the image provided). Now comes the tricky part; will you be able to establish contact with an alien culture that might not resemble you at all, or is such an endeavor simply doomed to fail due to the differences between you two?
