An image of the Nexus 7 tablet was just spotted on Google's internal servers, but it now appears there's another device that Google will announce at its annual developer conference today: the Nexus Q.

It's a home media center device that plugs into your television and powered by Android, Google's smartphone operating system. You can control the device with an Android smartphone or tablet.

It will cost $299, according to the Google Play store.

You can access movies and music you've bought through Google (as well as YouTube videos) and play them on your television, or through speakers you plug into it, like the Apple TV.

You can follow the full announcement on our live blog.

A landing page for the Nexus Q has also appeared on the Google Play store. Here's the description of the device:
