This is the first time that a piece of Mars here on Earth has been shown to contain opal.
Microbial life thrives in these conditions, and opal can trap and preserve these microbes for millions of years.
Lee and his team built their study on this discovery made by NASAs rover.
This research paper has been published in the journal Meteorites and Planetary Science, in the June 30 edition.
