Astrobites – making leading edge astrophysics readable

The astrobites (astro-ph reader’s digest) project seeks to present the latest reports on leading edge astrophysics research in a way that is understandable at an undergraduate level.

 Astrobites is a daily literature journal summarizing new astrophysical research posted to astroph. Astrobites is written by graduate students for undergraduates. Read more about our goals.

For example, much of this description of a paper on exoplanets around M dwarf stars should be comprehensible by even non-science undergrads: The Frequency of (Habitable?) Planets Around M dwarfs – astrobites.
