I think that when it comes to news, you are never going to get a completely unbiased opinion. Some networks wear their biases on their sleeve, others maybe not so much. For example, a lot of people like to hate on Fox News, but if you understand their bias and agenda, you can still get some benefit out of reading it (although still better to look elsewhere).
Personally, the only news website I use a lot is a website called RealClear News. They have various websites for different topics, like realclearpolitics.com, realclearscience.com, etc. They are not a reporting website themselves, but often find the best articles on a certain topic and give links to them, usually using the most unbiased and informative sources on the internet. Still not always perfect, but better than most, and its a good way to find out what's going on in the world.
