A newly completed analysis of Perseverance’s first images from Mars finds that the landing site, Jezero Crater, was really a lake that was fed by a river, with sedimentary layers, flash floods, and strewn boulders. Plus, Central African biomass burning, Arctic permafrost melting, and we look at jewelry that celebrates upcoming missions.

An analysis of the most recent sample taken from the Moon and returned by the Chang’e-5 mission shows that the basaltic rock is about two billion years old. This age implies a previously unknown heat source in the region. Plus, how plants and animals record climate change and this week’s What’s Up.

While searching for objects deep in the universe’s history, at about three billion years of age, researchers found six massive but “dead” galaxies in Hubble and ALMA data, a strange finding for a time period known for prolific star birth. Plus, planetary science from the EPSC2021 conference and this week’s What’s Up.
