Has Anyone Found a Lost Comet?!
Comet D/Lexell has been lost to memory since its discovery in 1770. Can modern astronomical methods track it down?
Not Quite a Star, Not Quite a Planet: A Planetary-Mass Object in AB Dor
In or out? Today’s paper explores whether or not an unusual object belongs to the AB Doradus moving group—and what it means if it does.
A new kind of animal in the exoplanet zoo
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.
Exploding stars and sleight of hand: A case of magnetic misdirection
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.
Cloudy with a chance of coronal mass ejections
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.
