Can Arduino Uno read analog voltages more than 5V?

Dear Arduino Lovers,

I want to measure analog voltages more than 5 v (upto +/-20V) with Arduino Uno.. Can anyone tell me the process?

Use a voltage divider to ensure the peak voltage never goes over 5V (assuming your using a 5V arduino and not a 3.3V one).

Yes, this is true. But i want to know that whether we can do something with its AREF line.

No.
Aref can not be taken higher than theprocessor's supply voltage which is 5V
