Exploring the Universe through Different Eyes

The image showcases galaxies from a cutting-edge cosmological simulation, revealing how they would look if observed by two of humanity's most powerful space telescopes. On the left, galaxies are displayed as if seen by the Hubble Space Telescope in ultraviolet and visible light, highlighting the vibrant glow of young stars and the dimming effect of interstellar dust lanes. On the right, the same galaxies are shown through the lens of the James Webb Space Telescope, capturing their expected appearance in the near and mid-infrared spectrum that is dominated by emission from dust grains and older stars. By comparing predictions from these simulations with observational data from diverse telescopes, astrophysicists gain invaluable insights into the processes of galaxy formation and evolution across cosmic history.
