Inferred yields of oxygen and iron from core-collapse supernovae agree with expectations for a model in which many stars that are lighter than 40 solar masses implode rather than explode.

The five newly discovered dwarf galaxies are star forming, blue, and gas rich, and they are all curiously aligned in a straight line across the plane of the sky, with three of them rotating in the same direction.

Precession of the disk around one member in a binary system — caused by tidal torques of the star’s neutron-star companion — may be responsible for the long-term flux variations of the system.

Researchers present the first exoplanet candidate from a new neural network pipeline; the newly identified planet is likely five times wider and 29 times more massive than Earth.

Simulations explore the accretion of a turbulent cooling medium onto a supermassive black hole, tracing the formation of magnetized filaments, thick magnetized disk, and a hot, turbulent flow.

Mid-infrared emission owing to an unexpectedly high temperature could be due to an active surface region or a ring system made up of small grains; either possibility would be unprecedented.
