Dark energy is weakening and the universe could (eventually) collapse, study says

This multi-wavelength image from NASA shows a universe full of galaxies that are various shapes, colors and sizes. Most are small while a handful are somewhat larger. A few stars are also scattered across the image.

The Dark Energy Spectroscopic Instrument (DESI) is studying dark energy and the accelerated expansion of the universe.
