Is it possible to Mix n' Match Two Separate Websites

We have a website, and a blog. They have separate domain names.

Is is possible to have the latest blog posts from the blog somehow display on the homepage of the website (as well as the homepage of the blog)

I suspect this is not possible and the easiest way might be to merge the blog into the website. i.e. import the blog over to the website’s servers?

Hope this makes sense! Thank you.
