   New experiments suggest that molten rock deep inside Earth can absorb and store large amounts of dissolved oxygen under extreme pressure. Lees meer

   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. Lees meer

   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.
