Top: an example of a chop-subtraction image pair from VLT/NEAR. Image B, following 0.05 sec after A, is subtracted to remove the detector bias, thermal background, AGPM glow, and excess
Earth’s stratosphere — NASA Although the high-altitude limit for microbial survival in the Earth–atmosphere system has remained a scientific curiosity and topic of study, the ecological significance of long-distance microbial
Physicists have developed a novel approach to solving one of the most persistent problems in theoretical physics: uniting gravity with the quantum world. In a recent paper published in the
