Science journalism is probably one of the least profitable reporting fields, and it's already cronyistic in general.
Futurism.com is good for just getting all the links together, while the actual reporting isn't too impressive, and of course, avoid all editorials
nationalgeographic.com is still good at on site nature stuff, otherwise they just take articles and expand on them
Needles to say, the interns at nasa.gov do their best to pack information in their releases
avoid the ESA site, they're very amateurish
