Cool, hazy exoplanets might look a lot like Saturn’s moon Titan. Today’s post explores the possible atmospheres of exo-Titans around a variety of host stars.
Supernova remnant magnetic fields may play a key role in accelerating electrons to relativistic velocities. West et al. investigate the magnetic field conditions inside young supernova remnants and discover that they may not be as well-behaved as they appear.
Coronal mass ejections strip away planetary atmospheres and cause raging geomagnetic storms on Earth. In today’s paper, the authors test a tool that could one day be used to predict the occurrence of coronal mass ejection impacts and the severity of geomagnetic storms.
Slowly-rotating Venus has some seriously speedy clouds. Using near-infrared images from Japan’s first Venus orbiter, Horinouchi and collaborators study the atmospheric dynamics of our strange sister planet.
NGC 3199 is only the fourth Wolf-Rayet nebula to be observed in X-rays. Toala et al. present chemical abundances for this nebula and find that the star that produces it, once considered a runaway star, might not be so far from home after all.
