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.
From Large to Small: Astrophysical Signs of Dark Matter Particle Interactions
The dark matter halos of galaxies and clusters of galaxies—objects of literally astronomical dimensions—have lots to say about the mysterious, likely subatomic, dark matter particle.
SETI Near and Far – Searching for Alien Technology
Finding extraterrestrial intelligence would be one of the most enlightening and profound discoveries in history. Today’s post looks at two potential means of finding extraterrestrials by seeing their advanced technology elsewhere in the Milky Way and the Universe.
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.
Magnetars: The Perpetrators of (Nearly) Everything
Extreme transient events are pushing the limits of our standard explosion models, but magnetars may save the day.
