Meet the AAS Keynote Speakers: Dr. Kate Follette
Today, we interview Dr. Kate Follette, who is an Associate Professor of Astronomy at Amherst College, about her Plenary Lecture at #AAS245
Guide to Adaptive Optics
Adaptive optics is a key technology for modern astronomical observations, and we’ve got a great overview of it for you in this guide!
UR: The Orbit and Growth of HD 142527B
In the latest of our #UndergradResearch series, discover William Balmer’s research on how direct imaging can show us more about planet formation!
H0ly Cow! A New Measurement of the Hubble Constant
The field of cosmology just can’t seem to agree on a value of the Hubble constant, so astrophysicists attempt to provide a new, independent measurement using strong gravitational lensing.
Optics to outrace them all
Astronomers are using a once-secret technology to scrutinize Kepler stars. Are rocky planets headed for a takedown?
Zooming in on Betelgeuse
Today’s paper uses adaptive optics and polarized visible light to probe Betelgeuse’s secrets. These observations have lots to tell us about interactions among the star’s surface, the closest and most-recently-ejected clumps of gas, and brand new polarized dust.
