Astronomers have measured the age of VVV CL001, a faint globular cluster hidden behind dense clouds of dust near the center of the Milky Way.
Infrared observations and the Hubble Space Telescope helped identify 155 cluster stars, revealing an estimated age of 13.4 billion years.
That places this ancient stellar group remarkably close to the age of the universe itself. If future observations confirm the result, VVV CL001 could raise important questions about how early the Milky Way—and its oldest stars—actually formed.

Astronomers investigated GRB 260310A, a strange cosmic explosion that produced a surprisingly bright afterglow despite its weak initial gamma-ray burst.
Observations revealed that the explosion came from a massive star, but Earth viewed its powerful jet from an unusual side angle. A delayed X-ray brightening also exposed a complex structure, with an ultrafast central jet surrounded by a slower, wider outflow.
