Simulations suggest that it may be possible to detect pre-explosion outbursts of supernova progenitor stars, even as far as hundreds of days in advance of the ultimate explosion.

Existing data cannot yet constrain the higher-order components of the magnetic field of Jupiter’s moon Ganymede, the largest moon in the solar system and the only one to possess a global magnetic field.

A search for astrospheres has turned up 10 stars with ultraviolet emission coming from a region with the shape expected for a spherically symmetric wind interacting with the interstellar medium.

If the luminosity of a tidal disruption event — when a star is ripped apart by a black hole — is proportional to the amount of material that falls onto the black hole, that suggests a roughly flat black hole mass function.

JWST continues to revolutionize every field it touches, this time giving researchers an entirely new view of the conditions within the interstellar medium of galaxies in the first billion years of the universe.

A catalog of flux-corrected and de-reddened spectra of 513 stars allows for simultaneous study of H-alpha and the 280-nanometer magnesium line, both of which indicate chromospheric activity.
