Astronomers from the European Southern Observatory have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe the protoplanetary disk surrounding a young star, revealing the presence of complex organic molecules that represent the building blocks of life. The findings mark the first time that such a discovery has been made. Read More
The Atacama Larger Millimeter/submillimeter Array (ALMA) has been used to study the formation of planets in a distant solar system, with the results likely to further our understanding of the process. This latest observation represents the first time the telescope has been used in its near-final configuration, and is the sharpest ever submillimeter wavelength image. Read More
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) group of radio telescopes have discovered a carbon-based molecule with a branched structure – a common feature in molecules that are required for life to form. Contained within a giant gas cloud in the star-forming region of Sagittarius B2, the molecule of isopropyl cyanide is the first hint that other complex molecules may form in space before finding their way to the surface of planets.

An international team of astronomers has used a range of telescopes including the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a pair of galaxies colliding at a time when the universe was just half its current age. The project made use of a gravitational magnifying glass created by the gravity of a galaxy between Earth and the subject, and required observations in both visible and infrared light. Read More
The last 12 meter (40 ft) antenna has arrived at the Atacama Large Millimeter/submillimeter Array (ALMA), pushing the project closer to its full operational potential. The final antenna was supplied by the European side of the venture, and completes the 66 dish array stretching across the Chajnantor Plateau in Chile's Atacama Desert. The telescope, which was inaugurated in March 2013, has already made a number of significant discoveries despite its incomplete nature. Read More
Astronomers have used the Atacama Large Milimeter/submilimeter array (ALMA) in Chile to view the largest stellar womb ever observed in the Milky Way. The gigantic object, which resides within the Spitzer Dark Cloud (SDC), is some 500 times the size of the Sun, and is still experiencing growth. Read More
Astronomers have used the Atacama Large Millimeter/submillimter Array (ALMA) telescope to more accurately map dusty star-forming galaxies in the early Universe. The new telescope is significantly more powerful than other similar devices, and in just a few hours, using less than a quarter of its full capacity, was able to double the number of confirmed observations of this type.

Even before the Atacama Large Millimeter/submillimeter Array (ALMA) was inaugurated this week, it was already rewriting history with its observations showing that a stellar baby boom took place much earlier than previously thought. But the pre-inauguration announcement isn’t a reflection that the ALMA team didn’t get to enjoy the official ceremony – like the first images released in 2011, the observations were taken while ALMA was still under construction.

Observations made with the Atacama Large Millimeter/Submillimeter Array (ALMA) in northern Chile, which is scheduled for completion this year, have solved a longstanding mystery in solar system formation. They showed how protoplanets forming around a young star can use their own gravitational pull to slingshot matter in the direction of their host star, fueling its growth. Read More
