AMP - Blogger's Alternative Solution
AMP (Accelerated Mobile Pages) used for mobile versions. Google news carousel is only done by AMP. In the market, most of the market leaders trust on it. Have you seen Google's top results with an AMP icon? That is the beauty of this.
Now the question is how you can do on your blog.
On blogger, you can not do this. You can use JSON-LD instead of this. Go to Google data markup helper and then make your code and paste them to your web page HTML.
You will see a change after some time not instantly.
