You can read more here at Microsoft.
Note that the actual boxed content at the bottom (e.g. above) depends on how you have 'My Bing' (I know, I know...) configured. Click on the hamburger menu top right and follow your nose, etc.
One striking thing about the Bing, err.. I mean 'Microsoft Bing' home page (in contrast to the Google 'all white' approach) has always been the daily photos, which are just stunning. And happily you can get these (for your own person enjoyment) on your Windows 10 Mobile phone as a desktop (or for other uses).
