First Contact: An Alien Encounter

By calling it the artifact, an object that may contain technology formed somewhere other than Earth. (intense music) What's amazing is how this whole extraordinary saga began with just one signal. That's all we had to go on. It took another five or six days before the first image appeared, and when it did, it was really grainy. Now, just in the last few hours, the first detailed pictures have started to appear, and they'll be vital for helping us understand what this object is and where it came from. (intense music) From what we've seen so far, the object appears to be tumbling through space. There's no sign of it moving under any kind of control. An extraordinary thought, given that it's almost 200 miles long, and traveling at speeds we've never seen before. These images raise so many questions. (intense music) Is this a structure in its own right or could it once have been part of something larger? (intense music) Is it genuinely artificial? And if so, what created it? (intense music) And perhaps most important of all, where did it come from? (intense music)
