Ground-based imaging shows how individual volcanic plumes interact as they are deposited on Io’s surface, creating measurable changes on this dynamic moon.

A newly discovered dense molecular ring in a young, cold star forming region gives a detailed glimpse into the inner workings of the regions in which massive stars form.

Though nearly all high-mass galaxies harbor massive central black holes, the black hole occupation fraction decreases to 66% for middling galaxies and just 33% for dwarf galaxies.

Optical, ultraviolet, and X-ray observations may provide the key needed to link quasi-periodic oscillations in jets to Lense–Thirring precession of the accretion flow in a Seyfert galaxy.

Simulations suggest that JWST’s Near-Infrared Camera should be able to detect ring systems around exoplanets, provided that the rings stretch to substantially larger radii than that of Saturn’s A ring.

For lightning to be responsible for the level of nitric oxide estimated to be present in Venus’s atmosphere, it must release more energy per strike or strike more frequently than it does on Earth.
