A different kind of planetary ring
Higher-order effects are beginning to surface in the photometry of exoplanets. Today we look at the way particles can add a ring to an exoplanet’s silhouette.
Best exoplanet destinations for mountain climbers
An novel method that could add texture to other worlds.
Have we been hit by a supernova?
Today’s paper describes models of what a nearby supernova would do to a young planetary system, and looks at whether the same may have happened to our own solar system.
The Planets in the Gaps
We’ve strongly suspected they’re there. A new method promises to prove it.
Deflating a Planet: Helium Loss in the Atmosphere of Wasp-107b
It has long been theorized that exoplanet atmospheres should be partially composed of helium — now we finally have our first detection in the atmosphere of Wasp-107b. Today’s bite explains how the authors observed helium and discuss what this means for the atmosphere of this planet.
