Washington: Astronomers have discovered what may be the first known example of a globular cluster about to be born - an incredibly massive and extremely dense yet star-free cloud of molecular gas. Globular clusters -- a dazzling group of up to a million ancient stars -- are among the oldest objects in the universe.

With Atacama Large Millimeter/submillimetre Array (ALMA) telescope, the astronomers were able to find and study in detail a pristine example of such an object before stars forever change its unique characteristics. Most globular clusters formed during a veritable "baby boom" around 12 billion years ago at a time when galaxies first assembled.
