Astrophysicists are mapping a vast, hidden structure in the gas around the Sun that behaves like a tunnel carved through ...

ALMA in Chile receives 145 low-noise amplifiers for Band 2, enabling detailed studies of cold interstellar gas, planet-forming disks, and organic molecules in nearby galaxies.

Diffuse interstellar bands (DIBs) represent one of the longest-standing enigmas in astronomical spectroscopy. These broad absorption features, observed in the optical and near-infrared spectra of ...
