How to report a discovery

Hi, once again, I'm having trouble to accurately put my thoughts into words. Some time ago, I was reading a scientific article about the possibility of life on Titan, a moon orbiting Saturn. When I tried to summarize what I had just read, the first sentence that came to my mind was "Scientists believe they may have found another celestial body that might be capable of sustaining life." However, this sentence is problematic as it suggests that the scientists in question weren't aware of the planetoid's existence prior to hypothesizing that it might harbor life.

I considered an alternate way of saying it ("Scientists believe they may have discovered that there might be life on another celestial body"), but thought it was too vague (i.e. it could be referring to any celestial body) in addition to being awkward-sounding.

Finally, I thought of the following sentence: "Scientists believe they may have found evidence of possible life on another celestial body." However, I have a problem with the word "evidence" as it makes it sound like an irrefutable discovery. In addition, I can't help but think there must be a simpler way of putting it (preferably, without having to specify the name the celestial body in question.) Any suggestions?

Also, I would appreciate if you could point out ANY mistakes or inaccuracies you find in this message. Any mistake -- even the slightest! Precision of speech is sacrosanct to me. Thank you.

Thanks, Ray. I have this regrettable habit of splitting infinitives. Do you detect any more mistakes / incorrect sentence structures on my part?

Thanks to everybody else on this thread. Is there really no other way of wording this? I understand that the word "evidence" is appropriate in my example, but surely there must be an easier way of saying it. After all, it only occurred to me to use the word "evidence" after I failed to construct the sentence in any other way.

Your modifications make my statements sound too conclusive (in my opinion.) Is it ungrammatical to use so many auxiliaries in the same sentence? Did you feel my original sentences sounded awkward?

Your last suggestion sounds acceptable to me. (i.e. "Scientists have discovered evidence that they believe points to the possibility of life on another celestial body.") In fact, it's PERFECT! However, I'm still trying to find a shorter, more casual (and yet accurate) way of wording it... (Read the second part of my previous post.)

Well, thank you in advance. Your help is much appreciated.
