Has NASA found life on Mars? "Major science finding" to be announced

NASA has called a press conference for Monday when details of a "major science finding" from its ongoing exploration of Mars will be revealed.

The space agency says the 'Mars Mystery Solved' briefing will take place at 11.30am EDT at the James Webb Auditorium at NASA Headquarters in Washington.

Some reports suggest the agency might have discovered life on Mars, while others think it could be the discovery of liquid water, a key ingredient for a planet's suitability for life.
