The Sphere lit up the Las Vegas skyline - for the first time - on the Fourth of July while fireworks exploded overhead. 

Sphere stands 366 feet tall and spans 516 feet across — the largest spherical structure in the world.

The Exosphere features 580,000 square-feet of fully-programmable LED lighting – making it the largest LED screen on Earth. 

Sphere opens in Las Vegas on September 29 with the first of 25 sold-out performances by U2:UV Achtung Baby Live at Sphere.
