I don't know how to make this simple and I don't know about every situation. End of disclaimer.
A large percentage (99?) of imagery you see in Google Earth and in every other GIS'ish application stores some version of imagery on your computer. It makes moving around from one place to another faster if the application can grab a copy of imagery first from RAM and then from your hard drive. Otherwise the app calls the server, delivers some information about your area of interest, clips and processes one or more image versions and delivers it back to you computer or cell phone. It takes time and loads of bandwidth.
Google is aggressive in mining all the public sources of aerial imagery to use in their georeferenced apps. For a fact, there's no aerial imagery for anywhere in the United States over 3 years old and I'd bet almost all of the country, every square foot, has been photographed in the last two years.
My bet is that old imagery you're looking at is what's been stored in a cache in your device. You can and should clear it. Then, the application is forced to call the imagery server for the latest.
Here's a link to how to do it:

PatinPA - Pennsylvania I presume? The state of and Penn State have been among the most aggressive in collecting, acquiring, and providing aerial imagery.
Here's one place to look. As it is with a lot of these things it takes some motivation to learn how to arrive where you want to be.
