confirmed the existence of black holes in the core of the Milky Way and verified the accelerating expansion of the universe.

The Southern Ring Nebula - This huge cloud of dust and gas ejected by dying stars is about 2,500 light-years away.
Stephan's Quintet - The five galaxies in this visible group are 40 million to 290 million light-years away. This is the largest-ever image of Webb.
