Choose your own adventure: 3 ways to kill a massive disk galaxy
What kills the most massive disk galaxies in the Universe? Their own bulge, a sneaky bar, or a giant black hole? Let’s find out!
The Giant Bubble Driving Nearly All Nearby Star Formation
We’ve known for some time that we reside in the Local Bubble, a cavity of low-density gas excavated by an orchestra of dying stars ~15 Myrs ago. Today’s authors find that this Bubble’s expansion is driving nearly all nearby star formation.
The Recipe For Star Cluster Soup
Making a star cluster from scratch is no easy task. Today’s paper addresses the big question: what does it take to get the recipe right?
Counting clusters to probe ancient star formation
What can counting globular clusters tell us about a galaxy’s star formation history? Today’s authors investigate using Hubble Space Telescope observations.
Astrobites at AAS 239 Virtual Events: Day 3
We report on Day 3 of the virtual events based around the cancelled winter AAS meeting.
