New modelling suggests the Southern Ocean could one day release the vast heat it has stored from greenhouse gas pollution. If CO₂ levels were pushed to net-negative, deep convection may trigger a sudden “thermal burp” that warms the planet for decades. Though idealised, the study shows how Antarctica’s surrounding seas could shape long-term climate outcomes.

Scientists have spotted an unusual gravitational-wave signal that may reveal the universe’s first primordial black holes—tiny relics dating back to the Big Bang. Recorded by LIGO–Virgo–KAGRA in November 2025, the event involves an object far lighter than any known stellar remnant. If verified, it could reshape theories of black holes and dark matter.

Astronomers using the James Webb Space Telescope have detected unexpected ultraviolet radiation around five young protostars in the Ophiuchus molecular cloud. Since infant stars are not expected to emit UV light, the finding challenges long-standing star-formation models. Researchers ruled out external illumination from nearby stars, concluding the UV must originate w...
