A new, wiggly ruler for measuring the universe
Wiggly rulers don’t seem like good measuring devices, but Velocity-induced Acoustic Oscillations might be an exception.
A Planetary Death Census
Planets are occasionally found swallowed by their dying host stars. Where and how often does this happen?
Evaporating Disks With Massive Stars
Radiation from massive stars can melt away protoplanetary disks. What can the leftover disks tell us about the environment from which they formed?
Teaching an old dog new tricks: Applying color-magnitude diagrams to semi-resolved galaxies
Applying color-magnitude diagrams to distant, semi-resolved galaxies may break new ground in understanding stellar populations on a massive scale.
Let’s talk about Exoplanetary Photospheres
How, and when does the wavelength dependence of photospheric radius of an eclipsing exoplanet become too important to neglect?
A Protoplanetary Disk with a Tail
The sites of planet formation seem to be anything but orderly and a recent discovery may help explain the observed wide variety of exoplanet configurations.

A Study in Stereotypes: What People Think of Physicists vs. Biologists
What do people think of scientists? A group of physics and psychology researchers teamed up to identify stereotypes about physicists and biologists in order to refine what stereotypes are held about not only science as a whole, but specifically the field of physics.
Astro2020 science white papers are in and the decadal survey is underway!
Just over a week ago astronomers from all over the United States submitted white papers to the Astro2020 decadal survey on topics across the field of astronomy. They are great short summaries of topics from planetary systems to galaxy evolution to multi-messenger astronomy and everything in-between.
Science and the EU: how Brexit will impact astronomy
Brexit might not seem like a scientific question, but scientists in the UK and across Europe are already feeling its impact. How will leaving the EU affect astronomy in the UK?

Meet the AAS Keynote Speakers: Dr. Catherine Espaillat
How do the protoplanetary disks around young pre-main sequence stars evolve into planetary systems? Come attend Dr. Catherine Espaillat’s plenary talk “From Disks to Planets: Observing Planet Formation in Disks Around Young Stars” at #AAS233 to know more!
Meet the AAS Keynote Speakers: Dr. Julianne Dalcanton
The Milky Way’s nearest neighbor, the Andromeda galaxy, is a promising target for deep multi-wavelength observations. Come listen to Prof. Julianne Dalcanton talk about her work catching up with the neighbor at #AAS233!
Meet the AAS Keynote Speakers: Dr. Caitlin Casey
Some galaxies are easy to find—others, like dusty galaxies with extreme star formation, are a bit harder to track down. Come to Professor Caitlin Casey’s #AAS233 talk to learn how we can find these galaxies in the “obscured early universe”!
