An article published in “The Astronomical Journal” reports the study of a nursery of stars in the great molecular cloud cataloged as W49A. A team of astronomers led by Professor Christopher De Pree of Agnes Scott College compared new observations conducted with the VLA (Very Large Array) at infrareds and radio waves of ​​W49A’s central area with observations conducted with the same radio telescope between 1994 and 1995. The result is the identification of new activities with supersonic gas movements in three regions and a high-speed jet in one region.
