For decades, the mystery of NASA's 700 missing Apollo 11 tapes fueled conspiracy theories. The truth is not a cover-up, but a story of cost-cutting.
Scientists have proposed a high-risk mission to catch interstellar comet 3I/ATLAS by sending a probe on a daring dive toward the Sun to achieve record-breaking speeds.
ESA's Proba-2 satellite captured breathtaking images of a 'ring of fire' solar eclipse on Feb. 17, 2026, an event almost entirely missed by observers on Earth.
A surge in satellite mega-constellations, with over a million new satellites proposed, threatens to permanently alter the night sky and create a crisis in Earth's orbit.
London is preparing to host Space-Comm Expo, Europe's largest space industry event, on March 4-5, gathering over 5,400 global leaders to discuss technology, defense, and investment.
NASA has launched a series of sounding rockets into the aurora borealis from Alaska to study the complex electrical systems that power the northern lights.
Astronomers have witnessed a massive star in the Andromeda galaxy vanish, concluding it collapsed into a black hole without a supernova explosion.
Scientists are re-examining data from NASA's 1976 Viking missions, arguing that the probes did find evidence of microbial life that was misinterpreted at the time.
International Space Station research has been vital in preparing for the Artemis II lunar mission, contributing critical life support systems, health studies, and observation techniques.
Scientists analyzing three-decade-old NASA data have discovered a massive underground tunnel on Venus, likely a lava tube, suggesting the planet may be geologically active.
