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.

Astronomers were surprised when the VLA revealed that a bright new object has appeared near the core of a famous galaxy. They think it’s a second supermassive black hole, indicating that the galaxy has merged with another in the past.

ALMA has made the first complete millimeter-wavelength image of the ring of dusty debris surrounding the young star Fomalhaut.
