Years of data collection and research with Curiosity is building a more complex picture of ancient Martian lakes (image credit: NASA).

The Curiosity rover has been at Gale Crater on Mars since its landing on the red planet in August of 2012, and over the last 5 years has assembled a strong case indicating the conditions on Mars in the distant past were favourable for life. Researchers from Stony Brook University in New York recently took a comprehensive look at Curiosity's findings over the years and has reached a conclusion that within the lake that existed at Gale Crater, there is evidence of stratification. This means that there is evidence of "sharp chemical or physical differences between deep water and shallow water." Ancient Mars is looking more and more interesting as Curiosity gathers more and more data.
