Renowned cosmonaut Valentin Lebedev, who set a world record for his stay in Earth's orbit, is rapidly losing his eyesight. "I suffered from a lot of radiation in space. It was all concealed back then, during the Soviet years, but now I can say that I caused damage to my health because of that fligh...
Every 5.6 years, EE Cephei is eclipsed by an unseen companion. The eclipse of the 10.9-magnitude long period eclipsing binary in the constellation Cepheus lasts 17 days. The long period variability of B5 star EE Cephei was first identified by the Italian astronomer Romano in 1956. The star syste...
Scientists have shown that tiny crystals found inside bacteria provide a magnetic compass to help them navigate through sediment to find the best food, in research out today. Researchers say their study, published in the Journal of the Royal Society Interface, could provide fresh clues to explai...
A Chinese man originally thought to have been struck by lightning was in fact killed by a small weather rocket whose existence was only discovered when his body exploded during his cremation. Inquiries revealed that the rainfall on the day of the original disaster was triggered by the local weather...
