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.
A Recipe for Mini-Neptunes
Mini-Neptunes are among the most common type of planet in the galaxy. Are they as easy to build as we might think?
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.
What is the Most Massive Object in the Universe?
Trying to find the most massive galaxy cluster in the night sky can be hard. Comparing predictions of these masses to observed clusters? Even harder. An insight into the world of Halo Mass Functions and their tail-ends.
A Contracting White Dwarf?
A peculiar X-ray binary may contain the first known white dwarf which is still in the process of contracting.
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.
