NASA to announce a 'major science finding' about Mars in anticipated press conference Monday

NASA is teasing a major discovery on Mars, but they're being tight-lipped and won't reveal the mystery until a Monday press conference, CNN reports.

The space agency will announced a "major science finding" at 11:30 a.m. Eastern, and will broadcast the event live on NASA TV and from its website, in a press release that announces a "Mars mystery solved."

Some are speculating based on the list of experts slated to make the announcement that NASA has found evidence of water, Business Insider reports. And where there's water, there's the prospect of life.

NASA currently has two rovers on Mars -- Spirit and Opportunity. One of the goals of the agency is to determine whether life on Mars ever existed.

In July, NASA called a press conference to announce that one of its spacecrafts found a planet similar to Earth, dubbed Kepler-452b, CNN reports. The agency hopes to send humans to Mars in the 2030s.
