A New Determination of the Mass of NGC 3603-A1 - the Most Massive Binary Known? #binary star system NGC 3603-A1 is one of the most massive binaries ever discovered in the Milky Way Galaxy.

The formation and evolution of dust in the colliding-wind binary Apep revealed by JWST: #binary Apep [...] reveal an intricate series of nested concentric dust shells that are abundant in detailed substructure. The striking regularity in these substructures between successive shells suggests an exactly repeating formation mechanism combined with a highly stable outflow that maintains a consistent morphology even after reaching 0.6 pc (assuming a distance of 2.4 kpc) into the interstellar medium."
