Unlike Twitter Trends located to the left of the screen, Facebook's Trending list is on the right of the News Feed.
The list is personalized, and includes topics based on "things you're interested in" and what's trending across Facebook , whether it's the Golden Globes, Miley Cyrus or something actually relevant like fracking or the crisis in Syria.
Each topic is accompanied by a headline that briefly explains why it is trending.
The new feature comes as more and more younger users are fleeing to cooler social networks like Snapchat and Instagram.
"Facebook is a space where people from all over the world gather every day to share their thoughts and participate in real-time conversations, from the highlights of the Golden Globes to the passing of Nelson Mandela."
"Trending is currently rolling out on web in selected countries and we are going to continue to test on mobile," Facebook's Chris Struhar, Engineering Manager said today.
"As with other features, expect continuous improvements from us over time."
It will be rolled out in to Australian, Canadian, US and UK Facebookers in the coming weeks.
