Story summary

In a groundbreaking study, researchers have uncovered over 15,000 kilometers of ancient riverbeds in Noachis Terra, Mars, revealing a once lush landscape. Led by Adam Losekoot, this research suggests that stable surface water existed during the Noachian-Hesperian transition, reshaping our understanding of Mars' climate from cold and dry to potentially wetter. The findings were shared at the Royal Astronomical Society's meeting in Durham.
