There is another possibility for improving this one ... there are a variety of possible texts available for use in various other parts of the game, so possibly Stardock could add alternative text for this and other anomalies (and Galactic Resources would be nice, too.) This'd mean you don't always get the same research assistant.
For examples:
1) The survey team spent a long time studying the (gas cloud). Eventually, they give up.
"Although there was something special here," the head of the chemistry lab reported, "we couldn't work out what it was. Quite frankly, it is beyond us at our current level of research. There's a lot we still don't know about science."
1a) "This one goes into the too hard basket."
1b) "What do you think we are, miracle workers? We don't know everything!"
2) "There was nothing to see here," the ship's captain reported, waving a hand vaguely. "We decided to move along."
3) After a brief investigation, the survey team conclude that all oddities here may be explained using existing theories.
3a) "There is nothing new here."
