ALMA reveals planet-forming potential of protoplanetary disk
ALMA planet-forming potential protoplanetary disk
2016/2/23
Astronomers struggle to understand how planets form in binary star systems. Early models suggested that the gravitational tug-of-war between two stellar bodies would send young planets into eccentric ...
Giant Planets Carving Paths around Four Young Stars,ALMA Observations Suggest
Giant Planets Carving Paths Four Young Stars ALMA
2015/12/22
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found the clearest evidence yet that giant planets have recently formed around four young stars. These new worlds, each p...
ALMA Witnesses Assembly of Galaxies in the Early Universe for the First Time
ALMA Witnesses Assembly of Galaxies Early Universe First Time
2015/8/4
The Atacama Large Millimeter/submillimeter Array (ALMA) has detected the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe. The new observations allow astronom...

ALMA Detects First Traces Smog Permeating Interstellar Atmospheres Early Galaxies
2015/7/13
Astronomers study the elements scattered between the stars to learn about the internal workings of galaxies, their motion and chemistry. To date, however, attempts to detect the telltale radio signatu...

ALMA Weighs Supermassive Black Hole Distant Spiral Galaxy
2015/7/13
Supermassive black holes lurk at the center of every large galaxy. These cosmic behemoths can be millions to billions of times more massive than the Sun. Determining just how massive, however, has bee...
ALMA Discovers Proto Super Star Cluster -- a Cosmic 'Dinosaur Egg' About to Hatch
ALMA Proto Super Star Cluster Dinosaur Egg
2015/5/25
Globular clusters – dazzling agglomerations of up to a million ancient stars – are among the oldest objects in the universe. Though plentiful in and around many galaxies, newborn examples are vanishin...
Why Do Starburst Galaxies 'Burst'? ALMA Sees Super Stellar Nurseries at Heart of Sculptor Galaxy
Starburst Galaxies Burst Super Stellar Nurseries Heart of Sculptor Galaxy
2015/3/4
Starburst galaxies transmute gas into new stars at a dizzying pace – up to 1,000 times faster than typical spiral galaxies like the Milky Way. To help understand why some galaxies "burst" while others...
ALMA finds best evidence yet for galactic merger in distant protocluster（图）
ALMA galactic merger distant protocluster
2014/12/1
Nestled among a triplet of young galaxies more than 12.5 billion light-years away is a cosmic powerhouse: a galaxy that is producing stars nearly 1,000 times faster than our own Milky Way. This energe...

Planet-forming lifeline discovered in a binary star system: ALMA examines ezekiel-like 'wheel in a wheel' of dust and gas（图）
dust gas
2014/12/1
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected a streamer of dust and gas flowing from a massive outer disk toward the inner reaches of a binary star system. Th...

2014/3/17
A team of Japanese astronomers has obtained a firm evidence of formation of a giant planetary system around a young star by the observations with the Atacama Large Millimeter/submillimeter Array (ALMA...
The exciting future of (sub-)millimeter interferometry: ALMA
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
The Atacama Large Millimeter/submillimeter Array (ALMA), presently under construction, is a revolutionary astronomical interferometer, that will operate at (sub)millimeter wavelengths. With unpreceden...
大毫米/亚毫米波望远镜ALMA实现闭环
ALMA 天文学家 银河系
2011/12/16
2009年11月20日，ALMA(The Atacama Large Millimeter/submillimeter Array)的3个12米天线在智利北部海拔5000m高的ALMA天文台，实现了相位闭合。这项工作成果是里程碑式，因为虽然在2009年10月实现了两架12米天线的干涉，但只有3架天线实现相位闭合才能消除大气挠动及仪器产生的误差，从而实现高分辨观测。
