The solar wind is filled with waves of oscillating plasma, and ion waves appear to be more common closer to the Sun than farther away, due to the factors that excite waves in the first place.
Based on eyewitness drawings by Carrington himself, researchers have assigned an unprecedented classification of X80 for this famous benchmark flare.
Discovering exoplanets around giant stars is difficult because these stars are inherently variable, showing slow radial velocity changes that can be mistaken for the tiny tugs of an orbiting planet.
Modeling of Europa’s broken and jumbled chaos terrain supports the idea that there may be shallow reservoirs of salty water embedded within the moon’s thick icy crust.
Researchers are using the positions of young stars to disentangle the spiral structure of our home galaxy, which is key to understanding how our galaxy formed and continues to evolve.
