Twinkle, Twinkle, Little Resonant Planetary System
The planetary system around the K2-138 star is the longest known 3:2 resonant chain. New radial velocity measurements reveal the properties of these rhythmic planets.
Dwarf Galaxies without Dark Matter
Today’s paper looks at observations of 19 low mass galaxies which appear to contain no dark matter, potentially challenging our overall understanding of galaxy formation.
An interplanetary collision — in a distant planetary system
Interplanetary collisions can explain a number of phenomena in our own solar system — here’s evidence of such a crash shaping the formation of two distant planets. Translate from an Astrobitos bite by Elena Gonzales Egea.
Speed check on the ‘fastest’ star in Gaia
This astrobite looking at a star that is moving so fast, it can escape our galaxy. But is everything as it seems?
Searching for Earth-like worlds with a fine-toothed (Astro)comb
A combination of infrared spectrograph and laser frequency comb provides unprecedented precisions in the hunt for habitable planets around nearby, cool stars.
