astrophysics - Is phys.org/space-news reliable source?

I found this page: http://phys.org/space-news/ . It seems to me pretty good page with interesting news and so on and I like that it is free. But I noticed in comments people arguing about the validity of the information and so on. Are they just "trolls" or is this page really bad source of information, if that is so, how much can I trust it?
Thanks in advance!
