https://crossingzebras.com/ is a decent source
I know Imperium.news used to be The Mittani and is basically a propaganda outlet for Goonswarm's power bloc.
Likewise evenews24.com at least used to be under the control of NC./PL as a more subtle propaganda outlet, but I've no idea what its deal is today.
I have to admit that when out-of-game news sites serve as a mechanism of information warfare, it speaks very well of EVE's metagame.
The founders: Xander Phoena, Niden, and Jeg Elsker hail from different groups. The corp, Zebra Corp, that the rag gets its name from, has been a part of several different major alliances, ranging from CO2, to Goonswarm, but doesn't appear to have any bearing on the reporting, itself.
