Feeding on the Cosmic Web
Observations of dwarf galaxies show that sites of active star formation have fewer metals. These galaxies may have been diluted by the impact of pristine gas from the cosmic web.
Searching for white dwarf companions around millisecond pulsars
Images from the Hubble Space Telescope show that there are previously unknown white dwarfs orbiting around pulsar companions.
Starspots to Measure Small Differential Rotation Rates
On using photometric data from Kepler to study starspots, and to measure differential rotation rates.
A Cepheid Anomaly
Today we take a closer look at rare system that might just be host to an even rarer Cepheid.
An Explosive Signature of Galaxy Collisions
Astronomers have known for a while that GRBs are sign-posts to galaxies which are forming lots of stars. But today’s paper used radio observations of the gas to connect that star formation to a recent merger.
SOFIA or American Sniper?
For the very first time astronomers have used the SOFIA spacecraft to do precise measurements of a transiting exoplanet!
