The first Carnival of Cosmology was a success, so we’re doing another one this month too! Our theme this time is “Observational Challenges”—defined broadly or narrowly. The Carnival will be on Friday, August 31, so please submit your contributions to me before 11:59 PM US Eastern time on Thursday, August 30.
