New Results from a Survey of Active Galactic Nuclei
A new special issue of the Astrophysical Journal Supplement Series introduces the second data release of an expansive spectroscopic survey.
Studying Solar BEARs in Their Natural Habitat
Researchers study some of the smallest solar active regions to understand what makes them release microflares.
When Planets Collect Comets
Exoplanets might ensnare comets that pass too close. Which planets are the likeliest comet catchers, and what would this mean for our interpretations of exoplanet composition?
Can Shock Waves Create the Conditions for Molecule Formation?
An outflowing jet from a young protostellar system at the heart of a dark, dusty cloud is one of the best places to study interstellar chemistry.
