The Hubble Space Telescope has done amazing work in helping us understand dark matter and dark energy. Here are some cool things it has discovered:
Measuring Distances: Hubble looked at supernovae, which are huge explosions of stars. These supernovae act like yardsticks for us. Because of Hubble's observations, we learned that the universe is getting bigger and stretching faster, which suggests dark energy is at play.
Gravitational Lensing: Hubble also studied how light bends when it passes near big objects in space, like galaxies. This bending shows us that dark matter exists and helps us see how it spreads out across the universe.
Galactic Clusters: By looking at groups of galaxies, Hubble found more evidence for dark matter. It figured out how much mass these groups have by watching how the galaxies move inside them.
Thanks to Hubble, we have a much better understanding of the universe!
