What is Wormhole Ethereum?

Could you please explain to me, in layman's terms, what exactly Wormhole Ethereum is? I've heard it mentioned in the crypto community but I'm still a bit hazy on the concept. Is it a new type of Ethereum? Or is it a bridge connecting Ethereum to other blockchains? Could you also elaborate on its potential uses and benefits? I'm quite curious to know more about this intriguing topic.
