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.
Using data from the Hubble Telescope and the ESO’s Very Large Telescope in Chile, a team of scientists have successfully detected clouds on an exoplanet and even measured their altitude. Plus, fossil evidence of humans’ arrival in North America and a review of the first episode of “Foundation” on Apple TV+.
Hycean worlds have hydrogen-rich atmospheres and are covered in oceans, making them prime candidates for the search for life outside our own solar system. These worlds are also more numerous and easier to find than Earth-like exoplanets. Plus, an update on the search for Planet 9 and how volcanoes may provide a climate safety valve.
New research has pinpointed small, violent faults caused by the breakup of an ancient supercontinent as the potential cause of a major loss in the rock record of the Grand Canyon, known as the Great Unconformity. Plus, using sky mapping tools to find earthly tombs and a review of Andy Weir’s “Project Hail Mary.”
Using a neutron spectrometer on board the Dawn spacecraft, scientists have found elevated concentrations of hydrogen in Ceres’ Occator Crater, which provides evidence of an icy crust. Plus, everything is on fire in the western United States, and we review “The Past is Red” by Catherynne M. Valente.
Based on X-ray detections from the Neil Gehrels Swift Observatory, scientists used the Chandra X-ray Observatory and found rings called light echoes moving out from a black hole and its companion star, reflecting off the surrounding dust clouds. Plus, solving the puzzle of the Sun and using glassy nodules to find a meteorite impact.
