April 22 (UPI) One of the world s most powerful radio telescopes, Chile s Atacama Large Millimeter/submillimeter Array, has identified a rotating infant galaxy in the distant universe with the help of a gravitational lens.

ALMA Discovers Rotating Infant Galaxy with Help of Natural Cosmic Telescope
Image of the galaxy cluster RXCJ0600-2007 taken by the NASA/ESA Hubble Space Telescope, combined with gravitational lensing images of the distant galaxy RXCJ0600-z6, 12.4 billion light-years away, observed by ALMA (shown in red). Due to the gravitational lensing effect by the galaxy cluster, the image of RXCJ0600-z6 was intensified and magnified, and appeared to be divided into three or more parts.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers found a rotating baby galaxy 1/100th the size of the Milky Way at a time when the Universe was only seven percent of its present age. Thanks to assistance by the gravitational lens effect, the team was able to explore for the first time the nature of small and dark “normal galaxies” in the early Universe, representative of the main population o

ALMA Lensing Cluster Survey team used a natural cosmic telescope to find a rotating baby galaxy. The involved scientists claimed that modern space telescope models couldn t do this.

This handout image of the giant, active galaxy NGC 1275, obtained August 21, 2008 was taken using the NASA/ESA Hubble Space Telescope?s Advanced Camera for Surveys in July and August 2006. It provides amazing detail and resolution of fragile filamentary structures, which show up as a reddish lacy structure surrounding the central bright galaxy. These filaments are cool despite being surrounded by gas that is around 55 million
