An away team discovers a big glowing orb that attempts communication and soon after this communication members of the team die due to an unknown cause. They then go to huge efforts and great risk to interact with the big glowing orb (the bulk of the story). Then after many deaths when they finally study the retrieved big glowing orb under controlled conditions back at base they realise it's a fairly simple machine trying to communicate the equivalent of 'stay away'. It was a warning sign, the same as a skull and crossbones. The real danger was the area around it.
It is tempting to think that human civilisation shows basically the same characteristics as human babies - it will literally put anything it finds in its mouth unless you stop it!
