Using the Atacama Large Millimeter/submillimeter Array (ALMA), scientists have detected a newborn star and the surrounding cocoon of a complex organic matter, for the first time.

Highlights

• The discovery revealed the hidden chemical complexity of Universe. It was published in a paper, in The Astrophysical Journal.
• The scientists used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile for observing a newborn star (protostar) in WB89-789 region. It is located in extreme outer Galaxy.
• They also detected a variety of carbon-, oxygen-, sulfur-, nitrogen-, and silicon-bearing molecules, including complex organic molecules comprising up to nine atoms.
• Observations reveal that, several types of complex organic molecules, like methanol (CH₃OH), methyl formate (HCOOCH₃), ethanol (C₂H₅OH), dimethyl ether (CH₃OCH₃), propanenitrile (C₂H₅CN), formamide (NH₂CHO), etc., are present in primordial environment of the Galaxy.
• The complex organic molecules act as a feedstock for larger prebiotic molecules.

Atacama Large Millimeter/submillimeter Array (ALMA)

ALMA is an astronomical interferometer comprising of 66 radio telescopes in Atacama Desert of northern Chile. The array observes electromagnetic radiation at wavelengths of millimeter and submillimeter. Array has been constructed at the elevation of 5,000 m in Chajnantor plateau. This location was selected for its high elevation and low humidity, which are essential factors for reducing noise and decrease signal attenuation due to atmosphere of Earth.
