A study of a well-known active M-dwarf star shows that the temperatures of its stellar flares are significantly lower than the canonical flare temperature of 10000K.

Using density functional theory calculations, researchers have shown that five of the six strongest diffuse interstellar bands can be attributed to carbon nanotubes that form in shocked circumstellar gas.

Galaxies containing two stellar disk components rotating in opposite directions appear not to have a single cause; the gas that creates the counterrotating component can come from mergers or accretion.

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.
