CANADA: A cosmic dinosaur is about to hatch, say scientists, who have discovered what may be the first known example of a globular cluster on verge of being born – an unimaginably massive, extremely dense, but star-free cloud of molecular gas.
A globular cluster is a huge compact spherical star cluster, typically of old stars, a dazzling agglomeration of up to one million ancient stars, in the outer regions of a galaxy.
Globular clusters are among the Universe’s oldest objects. Although abundant in and around several galaxies, about-to-be-born examples are vanishingly rare, and the conditions required to create new ones have never been detected …. until now, that is.
The globular cluster on the verge of being born was discovered by Kelsey Johnson, an astronomer at the University of Virginia in Charlottesville, and colleagues using the Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile.
