Typically, astronomers identify comets by their distinct atmospheres, or comae, and their tails, which are created as the sun vaporizes a comet’s ice. These features emit a glow when sunlight bounces off dust and water droplets. As gas escapes the body of the...
A new study reveals that two widely studied ultrathin superconducting materials are more sophisticated than they appear. Although they seem to behave like simple superconductors with a single energy gap, they actually contain two strongly interacting superconducting...
The effects of extreme space weather may be larger than previously thought, research in the journal Nature reveals. The paper, titled “Regression to the mean can explain saturation of geomagnetic storms,” is led by Dr. Nithin Sivadas of NASA’s...
