Globular Clusters Experience Bar Resonance Repercussions
What happens when a giant star cluster gets trapped in a dance with the Milky Way’s central bar? A new study reveals that bar interactions are likely responsible for where we find globular clusters in our galaxy today.
Cool It Down: Warm Jupiters Are Better Aligned Than Hot Jupiters
Hot Jupiters, especially when placed around hot stars, are notorious troublemakers. A new study suggests that their cooler cousins, the warm Jupiters, tend to follow the rules no matter what kind of star they circle.
Johannes Kepler and the Case of the Disappearing Sunspots
Astrobites reports on the use of Johannes Kepler’s pre-telescope sunspot drawings to re-examine irregular solar activity in the 17th century.
