From One Satellite to Another: Finding Clusters with Gaia
2 new globular clusters detected by Gaia, and what we know about them.
The Curious Case of Planetary Nebulae in Globular Clusters
Planetary nebulae where they shouldn’t be–how did they get there?
Globular Clusters as Cradles of Life and Advanced Civilizations
Could we find advanced civilizations in the globular clusters orbiting the Milky Way galaxy? The authors of today’s astrobite paper think we might…
Are There Age Spreads in Intermediate Age Clusters?
Can stellar clusters be host to multiple star formation events? The authors of today’s paper take a closer look…
UR #11: Our Galactic Magnetic Field and Stellar Autopsies
This month’s undergraduate research post features pulsars as a probe of our galaxy’s magnetic field, and the possibility of asymmetries in supernovae associated with gamma-ray bursts.
A Second Case for a Double Blue Straggler Sequence
The authors identify two distinct sequences of blue straggler stars in the globular cluster NGC 392. They hypothesize that one branch is formed via stellar mergers and the other is binary stars undergoing mass transfer. This is the second globular cluster found to possess this double sequence.
