GW170817: The X-Ray Emission Did What?
Astrobites reports on what we’ve learned from X-ray observations of the momentous neutron-star merger GW170817.
Are We Really Missing Small Galaxies?
We observe far fewer small galaxies than current theory predicts. Are these galaxies actually missing, or is this a problem of interpretation?
Probing the Structure of Our Solar System’s Edge
Our solar system is traveling through interstellar gas and dust. What happens where the solar wind and interstellar medium meet?
A New Look at Speeding Outflows
Chandra and Hubble have teamed up for a multi-eye look at an ultra-fast outflow speeding from the supermassive black hole at the center of a nearby active galaxy.
Biodiversity or Bust
Which stars are most likely to host planets capable of supporting complex life? Astrobites reports on a study seeking to answer this question.

Astrobites explores what it takes to form a mini-Neptune from the ingredients of an early solar system.
Pinning Down Properties of TRAPPIST-1
How correct are the properties we’ve measured for TRAPPIST-1, a nearby star with seven transiting, Earth-sized planets?
Lightweight Double Neutron Star Found
More than forty years after the first discovery of a double neutron star, we still haven’t found many others — but a new survey is working to change that.
