To make a star, the conditions inside interstellar gas clouds have to be “just right.” When it comes to a cloud’s magnetic fields, however, those conditions may range from powerful and orderly to weak and chaotic, new ALMA observations suggest.

New VLA images are helping astronomers understand the origin of a giant radio-emitting structure in a cluster of galaxies.

Astronomy outreach team travels to Chile to learn about U.S.-funded observatories.

ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate — a chemical building block of life.

Researchers are developing techniques that make it easier for scientists to produce high-quality visualizations of massive amounts of data.

The Boomerang Nebula — the so-called “coldest place in the universe — may get its frigid nature from a companion star supercharging a rapidly expanding outflow of gas.
