Anorthite formed during magma crystallization could have floated to the surface of Vesta, creating a primary anorthositic crust. —————

Nature Astronomy, Published online: 08 April 2024; doi:10.1038/s41550-024-02226-7 A radio-loud magnetar, XTE J1810–197, has been observed to precess shortly after an X-ray outburst. The precession decayed over the subsequent few months, which probably rules out freely precessing magnetars as the source

These Ti oxides can alter the photocatalytic properties and
