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.

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.
This astrobite looking at a star that is moving so fast, it can escape our galaxy. But is everything as it seems?
A combination of infrared spectrograph and laser frequency comb provides unprecedented precisions in the hunt for habitable planets around nearby, cool stars.
A possible super-Earth was discovered 6 light years from us around Barnard’s star, but does it actually exist?
Spectrographs here on Earth are getting good enough to detect tortoise-speed velocity shifts in starlight. That means that we need to understand the bubbling, broiling surfaces of stars to tortoise-level precision.
