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.

New experiments suggest that molten rock deep inside Earth can absorb and store large amounts of dissolved oxygen under extreme pressure. As magma rises toward the surface, falling pressure may release this stored oxygen into the atmosphere. The discovery could offer a new explanation for ancient changes in Earth's oxygen levels and reshape our understanding of the planet's geological history.

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. The discovery could help explain how many powerful stellar explosions remain hidden from our view. Thank you for listening to Bedtime Astronomy — your guide to the cosmos.

How do giant planets end up orbiting dangerously close to their stars? New simulations suggest that supersonic shock waves in their atmospheres can drain orbital energy, driving planets inward. Depending on the intensity of these disruptions, a planet may settle into a tighter orbit or lose much of its atmosphere. This mechanism could help explain the mysterious distribution of hot Jupiters and other giant exoplanets. Thank you for listening to Bedtime Astronomy — your guide to the cosmos.

Could comets have delivered the ingredients for life on early Earth? A University of Cambridge study challenges this long-standing theory, suggesting that high-speed impacts may have destroyed fragile organic molecules before they could trigger prebiotic chemistry. Mars may have offered more favorable conditions, but the findings raise new questions about how life’s essential building blocks first appeared.
