Astronomers using the Atacama Large Millimeter/submillimeter Array telescope have discovered starburst galaxies earlier in the Universe’s history than they were previously thought to have existed.

ALMA, the Atacama Large Millimeter/submillimeter Array, was officially inaugurated today in a ceremony that brought together representatives from the international astronomical community.

Astronomers have used the ALMA telescope to get their first glimpse of a fascinating stage of star formation in which planets forming around a young star are helping the star itself continue to grow, resolving a longstanding mystery.

One of the most powerful calculating machines known to the civilian world has been installed and tested in a remote, high-altitude site in the Andes Mountains of northern Chile, marking one of the major remaining milestones toward completion of the most elaborate ground-based telescope in history, the Atacama Large Millimeter/submillimeter Array.

Astronomers using the Atacama Large Millimeter/submillimeter Array have for the first time found that the outer region of a dusty disk encircling a brown dwarf contains millimeter-sized solid grains like those found in denser disks around newborn stars.

After an odyssey of design and construction stretching across more than a decade, North America has delivered the last of the 25, 12-meter-diameter dish antennas that comprise its share of antennas for the international ALMA telescope.

Combining the cutting-edge capabilities of the ALMA telescope with newly-developed laboratory techniques, scientists are opening a completely new era for deciphering the chemistry of the Universe.

A new observatory still under construction has given astronomers a major breakthrough in understanding a nearby planetary system that can provide valuable clues about how such systems form and evolve.

Two new and powerful research tools are helping astronomers gain key insights needed to transform our understanding of important processes across the breadth of astrophysics.

Astronomers using the partially completed ALMA observatory have found compelling evidence for how star-forming galaxies evolve into ‘red and dead’ elliptical galaxies, catching a large group of galaxies right in the middle of this change.
