Astronomers have confirmed a rare rogue planet, drifting without a star nearly 10,000 light-years away. Using gravitational microlensing, their distance and mass were measured, suggesting that free-floating planets may be abundant across the Milky Way. Upcoming telescopes, including NASA’s Roman Space Telescope and China’s Earth 2.0 mission, are expected to uncove...

Spain’s military communications satellite, SpainSat NG-2, was struck by a space particle while moving toward geostationary orbit. The incident occurred at an unusually high altitude, and the damage remains unknown. Operators have activated contingency plans as engineers assess whether the €2 billion mission can still be completed.

Experiments show RNA, a crucial molecule for life, could form naturally on early Earth with borates stabilising ribose and aiding phosphate production. Protoplanet impacts may have delivered RNA ingredients, supporting the RNA world hypothesis and suggesting life’s building blocks could emerge efficiently on Earth and potentially Mars.
