ALMA provides detailed look at galaxy formation in the early Universe

By - July 24, 2015 2 Pictures

Astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe distant clouds of star-forming gas from just 800 million years after the Big Bang. The findings represent the first time that the objects have been seen as anything more than just faint blotches, and the new data from the observations is set to significantly impact our understanding of the early Universe.

ALMA captures sharpest ever view of star formation in the distant universe

By - June 17, 2015 3 Pictures

The Atacama Large Millimeter/submillimeter Array (ALMA) has succeeded in imaging star formation regions in a distant galaxy, with a resolution six times greater than that achievable by the Hubble Space Telescope. The galaxy, dubbed HATLAS J090311.6+003906 or SDP.81, would ordinarily be far too distant to be observed in such impressive detail. However, thanks to an amazing cosmic coincidence, it has fallen foul of a phenomenon known as gravitational lensing, which essentially grants astronomers the opportunity to gaze into the distant past.

ALMA telescope reveals planetary formation in sharpest ever submillimeter image

By - November 14, 2014 4 Pictures
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

Discovery of new molecule suggests origins of life may reside in interstellar space

By - September 29, 2014 2 Pictures
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.

Cosmic "magnifying glass" used to identify distant colliding galaxies

By - August 29, 2014 2 Pictures
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

Final antenna arrives at ALMA Observatory

By - October 8, 2013 5 Pictures
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

ALMA telescope identifies early star-forming galaxies with unprecedented speed and accuracy

By - April 18, 2013 4 Pictures
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.

ALMA inaugurated after rewriting history of stellar "baby boom"

By - March 14, 2013 4 Pictures
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.
