The Atacama Large Millimeter/submillimeter Array (ALMA) has shared its highest-resolution image ever, featuring a star in the final stages of its evolution. 

ALMA is a ground-based telescope array located on the Chajnantor Plateau in the Atacama Desert of northern Chile. With 66 receivers, it is the largest millimeter-wave telescope in the world. Its latest observation — and highest-resolution snapshot to date — captures an up-close view of an evolved star called R Leporis that is located within our own Milky Way galaxy, about 1,350 light-years from Earth.
