Today, the European Space Agency (ESA) announced their plans to launch the Euclid mission in 2023, an ambitious mission to help us understand the mysterious force known as dark energy.

The mission hopes to shed light on this mysterious force by studying how dark energy affects the growth of galaxies over time.

The mission is set to last for six and a half years, and is expected to make huge advances in our understanding of dark energy.
