It is called Facebook Explore and it is Facebook way hot to keep you another few hours connected. This feed is not based on your liked pages of posts from friend. These posts are picked based on your preferences. So even that you never heard about these sources. You can find them. Whole idea could be beneficial for both sides. You should be able to see Explore in your left menu. However if you cannot there is link: https://www.facebook.com/explore/
