Exploring the Uncle Block Page

Uncle blocks (or Ommer) are created when two or more miners create blocks at nearly the same time. Only one block can be mined and accepted as canonical on the blockchain. The others are uncle blocks, which are not included but still provide a reward to their miners for the work done.
Please note that the uncle block page is only active and available before The Merge. Uncle blocks are no longer produced after The Merge, and this page only serves as historical reference purposes.

Uncle blocks are important to Ethereum as it helps to secure the network and allows for shorter block times. Users can view uncle blocks by going to Etherscan's View Uncles page.
