[Guest] The Walking Red: Why are you so quiet and overdense?
Why do we see so many massive, dead galaxies at early cosmic times? Guest author Tatevik Mkrtchyan illuminates a slice of the cosmic graveyard!
Deblurring the Dark Compact Object Picture with Microlensing
Lenses aren’t always made of glass, sometimes they’re made of dark matter compact objects! Today’s paper explores if and how we can tell primordial black holes apart from dark black holes using gravitational microlensing measurements.

[Beyond] Undergraduate astronomy degrees vary widely. Here’s what could be done to fix that.
A survey of physics and astronomy departments across the country has shown that degrees in astronomy can be pretty different. Read more about the AAS SURGE committee’s findings and recommendations!
Recycle your paper, plastic, and… pulsars?
Most pulsars gradually spin slower and slower, making weaker and weaker radio pulses until the pulses stop altogether. Today’s paper is about a star that has spun its neutron star companion back up, recycling it into a millisecond pulsar.
Dancing with the Blazars: Variability you can groove to
In today’s paper, we explore how blazar light curves can be transformed into music and the benefits of this for both scientists and science communication.
Life on the (Red) Edge
Today’s bite explores life on the vegetation red edge…and how we might find it on other worlds.

Breaking the Stigma around Community College: an astro[sound] bite
For many students, community college is part of their undergraduate education. We take a look at what community college is, the perception of a community college student, and share experiences from a few astronomers that started undergrad at a community college.
A Comprehensive Guide to the NASA FINESST award
A step-by-step guide to applying for the NASA FINESST graduate fellowship, including advice for writing a strong application!
Meet the AAS Keynote Speakers: Dr. Anthony Brown
For the past decade, ESA’s Gaia mission has helped reshape astronomy in more ways than you can probably think of. You can hear more about Gaia in Prof. Anthony Brown’s plenary talk at #AAS241!
