  NASA Juno Mission Uncovers Subtle Geometric Shifts That Challenge Existing Models of the Jovian Interior

  Scientists have refined Jupiter’s size and shape using modern radio signal observations, finding the giant planet slightly smaller and more flattened than earlier estimates. Though the difference is only a few kilometres, researchers say it greatly improves models of Jupiter’s interior, gravity, and atmospheric structure, offering deeper insigh...

  NASA’s GNEISS Mission Will Map Electric Currents Behind the Aurora

  NASA’s GNEISS mission will launch from Alaska in early 2026 to probe the electric currents that drive auroras. Two rockets will fly through glowing auroral arcs, releasing sub-payloads whose radio signals act like a CT scan. By mapping electron density and direction, scientists aim to improve space weather forecasting and better protect satellite...

  World’s Biggest Alien Search Enters Final Stage With 100 Mystery Signals

  SETI scientists are using China’s FAST radio telescope to examine the final 100 unexplained signals from the historic SETI@home project. While experts expect most to be radio interference, the search marks the culmination of a massive global citizen science effort and sets new standards for future hunts for extraterrestrial intelligence.

  NASA's James Webb Space Telescope Might Have Spotted Hidden Supermassive Black Holes

  Mysterious “little red dots” spotted by the James Webb Space Telescope may not be tiny galaxies after all. A new study suggests they are supermassive black holes wrapped in dense gas and dust, perfectly disguised in the early universe and shining intensely in infrared light.

  Scientists Study 100 Possible Alien Signals as Arecibo’s Historic SETI Search Concludes

  Scientists are studying 100 possible alien radio signals identified from Arecibo Observatory data, bringing the 21-year SETI@Home project to a close. Supported by millions of volunteers, the effort found no confirmed alien messages but set new sensitivity standards. Researchers say the findings will guide future searches using more powerful radio t...
