The biggest mass extinction event on Earth occurred at the end of the Permian period, resulting in the extinction of 95% of marine life and 80% of terrestrial life. Now, scientists have found that the terrestrial portion of the event lasted nearly ten times as long as the ocean version. Plus, a spaghettified star, the search for Moon Trees, all about Mars, and new works on dark matter and dark energy.

In another first for NASA’s Perseverance rover, a cube-shaped instrument called MOXIE, or Mars Oxygen In-Situ Resource Utilization Experiment, has successfully converted some of Mars’ atmospheric carbon dioxide into oxygen. Plus, a wild roundup of stories including exoplanets, sky maps, fast radio bursts, meteorites, and the problem with symmetry.

A survey of the stellar nursery in the Orion Nebula Cluster provides evidence that stars compete for material and their size depends on what they gather rather than their initial core size. Plus, NASA mission updates, fast radio bursts, neutron stars, visible novae, and mountain building in the Andes.

Exoplanetary Atmospheres and How to Understand Them

The Event Horizon Telescope collaboration released a new image yesterday that shows the black hole in M87 once again, but this time, with new details. Using polarized light, the team was able to capture photographic evidence of magnetic fields. Plus, Jupiter’s winds, baby stars, fossilized plants under Greenland’s ice, and our weekly What’s Up segment.
