Darwin’s Theory of Evolution, but make it planets
Can exoplanetary systems remain intact in dense stellar environments, or are their exoplanets destined to be flung into the far reaches of space? N-body simulations hint at characteristics that lead to a higher likelihood of survival.
How irregular rotation can change a galaxy’s metal content
It’s difficult to tell how the individual stars of a galaxy rotate. What can we find out just from their metal content?
New Horizons Images Show Fewer Small Kuiper Belt Objects than Expected
High resolution images from New Horizons of the surfaces of Pluto and Charon show ancient craters, but fewer than astronomers expected.
Halo assembly bias rides a gravitational tide
The local gravitational tides are really good at connecting the properties of dark matter halos to the cosmic web.
Putting Supermassive Black Holes on the Scale
A novel approach to estimate their mass may help reveal the relationship between supermassive black holes and the galaxies they inhabit.
Look! A Lensing!
Microlensing events can be predicted by following the path of high proper motion stars. In this paper, the authors do just that with Gaia DR2 data.

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?
New Authors for 2019!
A huge welcome to the new authors joining our team for 2019.
Astrobites at AAS 233: Day 4
We report on Day 4 of the winter AAS meeting in Seattle, WA. Highlights include an exploding space cow, a discussion of data in astronomy, the latest look at the possibility of life beyond earth, and an exploration of climate impact much closer to home.

Career advice
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”!
