Astronomers have discovered the remains of an ancient family of stars that was ripped apart by our galaxy, the Milky Way, some two billion years ago.
These elder stars once occupied a globular cluster, a spherical formation of stars, until they were flung into the Milky Way’s halo some 60,000 light years from Earth, forming a stellar river called the Phoenix Stream. This bygone globular cluster, known as the Phoenix progenitor, “apparently occupies a special position, which is distinctly different from the present-day globular cluster population observed in the local Universe,” according to a study published on Wednesday in Nature.
Whether or not stars have ghosts that can haunt us remains to be seen.
