Finding Galaxies in the Dark: Using Globular Clusters to Identify Ultra-Diffuse Galaxies
With their extremely low surface brightness, ultra-diffuse galaxies are very difficult to detect, but a recent study has spotted one by searching for its globular clusters.
A recent Focus Issue of the Astrophysical Journal Letters introduces the fourth version of the gravitational wave transient catalog from the LIGO, Virgo, and KAGRA collaborations.
The “Rhythm” of the Interstellar Medium
Astrobites reports on the interplay between the interstellar medium and star formation in simulated galaxies.
What powers the prominent helium emission from Hebe, a gas clump seen just 450 million years after the Big Bang?
Noble Gases Along for the Ride
How did neon end up inside Earth’s mantle, and what does that tell us about how our planet formed?
Hydrocarbons keep turning up in surprising places. This time, they’ve been found near a pair of accreting supermassive black holes 3 billion years after the Big Bang.
What if Mars Were a Stranger (Thing)?
Astrobites reports on whether we’d even know what we were looking at if our familiar red neighbor were a stranger light-years away.
The galaxies FCC 224 and FCC 240 appear to be a rare example of a dark-matter-poor, globular-cluster-rich pair formed via colliding dwarf galaxies.
A recent study used the kinematics, chemical composition, and ages of thousands of stars to determine when the Milky Way settled into the spiral disk we know it as today.
