For the past couple of months, I have been following Dr. Phil Plait’s Bad Astronomy blog.
This is one of those blogs that you end up wishing you had been reading since the very first day. BA posts regular news updates and some stunning pictures from the world of astronomy (in particular) and science (in general). Plait also writes about the importance of skepticism and the abuse of the scientific method in areas such as homeopathy and the anti-vaccinations movement.
It is almost always interesting and well worth subscribing to the RSS feed.
