Satellites map Antarctica’s hidden bedrock, tightening sea‑level forecasts

Advanced satellite observations are producing higher-resolution maps of Antarctica's subglacial topography, revealing previously hidden bed features and drainage pathways. Improved elevation and radar-derived datasets narrow uncertainties in ice-sheet dynamics, enabling more accurate projections of ice loss and global sea-level rise over coming decades.

JWST detects lensed supernova pair — time delays could pin down the Hubble constant JWST has identified a pair of strongly gravitationally lensed supernovae whose light, emitted billions of years ago, will appear as multiple images separated by years to decades. Measuring those lensing time delays can constrain the Hubble constant and help resolve the Hubble tension.

Scientists pinpoint Sun’s gamma‑ray source: supercharged atmospheric particles Researchers at the New Jersey Institute of Technology traced intense gamma‑ray bursts from solar flares to a previously unknown population of particles in the Sun’s atmosphere, accelerated to millions of electron volts. The finding resolves a decades‑old mystery about the origin and mechanism of these high‑energy emissions.

JWST "little red dots" identified as nascent black holes shrouded in gaseous cocoons Researchers analysing James Webb Space Telescope images have identified the ubiquitous 'little red dots' as nascent black holes embedded in dusty, gaseous cocoons. Based on emission lines and surrounding gas morphology across multiple JWST deep fields, the result implies an unrecognized population of early black holes near the cosmic dawn.

JWST's 'little red dots' may be black holes, not ultra‑dense dwarf galaxies James Webb has identified compact red sources whose inferred stellar mass would make them the densest galaxies known; new analysis suggests these 'little red dots' could instead be accreting black holes or compact AGN, forcing a reassessment of their nature and JWST follow‑ups.

ESA advances Comet Interceptor launch after delay to another mission A delay to another European Space Agency mission has created an opening that allows Comet Interceptor to launch sooner than previously scheduled and under a more favourable profile. The change gives ESA an opportunity to enhance the spacecraft's performance and scientific return by exploiting the newly available launch slot.

NASA demolishes Marshall's historic Dynamic Test Stand and T‑Tower On Jan. 10 NASA demolished two National Historic Landmark test structures at Marshall Space Flight Center — the Dynamic Test Stand and the T‑tower — facilities that enabled Saturn V development and Space Shuttle testing. The removals clear the site for modernized infrastructure to support next‑generation space exploration.

Congress rebuffs Trump, preserves NASA science funding Congress has rejected President Trump’s proposed cuts to NASA’s science budget, preserving funding for key Earth and space‑science missions. The decision brought relief across the space community, averting immediate program cancellations and stabilising near‑term research and satellite schedules.
