Observations of SN 2021yfj reveal that its progenitor is a massive star stripped down to its O/Si/S core, which remarkably continued to expel vast quantities of silicon-, sulfur-, and argon-rich material before the explosion, informing us that current theories for how stars evolve are too narrow.

Geophysical data for the Cocos Plate sea floor suggest that basement outcrops along mid-ocean ridge flanks can discharge very large quantities of heat and fluid. This is indicative of high crustal permeability at the regional scale.

A strongly lensed galaxy at redshift z ≈ 6 is resolved into at least 15 star-forming clumps embedded in a rotating disk. Clump formation in this system, which is not predicted by cosmological zoom-in simulations, may be driven by disk instabilities with weak feedback, rather than past mergers.
