Do we have any data on the cosmic background radiation measurements?

The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity. ... This light set out on its journey more than 14 billion years ago

The CMB is visible at a distance of 13.8 billion light years in all directions from Earth, leading scientists to determine that this is the true age of the Universe.

So is it possible to go beyond this CMB ?
