FOCASing on the Metallicity Gradient of an Extremely Metal-poor Galaxy
Today’s authors explore a nearby analog of some of the earliest galaxies to form in the universe and measure a metallicity gradient.

Carl Sagan once said, “we are all made of star-stuff”. Even stars are made of star-stuff: coming from an older generation of stars! A new observation has allowed astronomers to turn back the clock and study the earliest stages of this cycle.
In the latest of our #UndergradResearch series, read about the work by Beryl Hovis-Afflerbach on the environments in which binary black holes originate!
A newly discovered Globular Cluster is one of the most massive and metal-poor in the Galaxy. In today’s paper, we examine the stars inside the cluster to see where it stands on the metal-poor podium.
For the first time, diffuse X-ray emission from young stars is identified in the Small Magellanic Cloud (SMC), using data from Chandra.
It’s an unpleasant fact of galactic astrophysics that most of the molecular gas in nearby galaxies is completely undetectable.
