Astrobites reports on work preparing for Lucy, a new mission that will fly by multiple asteroids near Jupiter in the late 2020s.

M31 and M33

Gaia measurements of thousands of stars are helping us to pin down the motions (and future collisions!) of the galaxies around us.


In the era of big data, we often rely on computers to do sorting, searching, and analyzing. Sometimes, however, there’s just no substitute for the human eye and brain.

SMBH binary

You might think that a passing star getting ripped apart by a supermassive black hole sounds like more than enough drama. But let’s take this a step further…

Fornax dwarf

Astrobites reports on why two (stars) aren’t always better than one — especially when you’re trying to track down dark matter in tiny galaxies.

astronomical software

In today’s world of astronomy research, software is centrally integrated into nearly everything we do. Isn’t it time we develop a consistent system for citing and preserving it?

Transiting Exoplanet Survey Satellite (TESS)

Here are some recent discoveries by NASA’s newest planet-hunting spacecraft, TESS, which launched last year.
