This animation visualizes the real cosmic distances between our galaxy and its neighbors, starting with the Large Magellanic Cloud, about 160,000 light years away, moving to the Andromeda Galaxy at 2.5 million light years, and stretching out to extreme systems like Malin 1, one of the largest known spiral galaxies, over 1.3 billion light years from Earth. These measurements are made using a combination of methods, stellar parallax for nearby galaxies, Cepheid variable stars for intermediate dist

When we look out into space, we are also looking back into time. ⏰ Astronomers can trace galaxy development by observing galaxies at great distances to reveal how they appeared long ago. This example—using the Hubble Ultra Deep Field—showcases how the appearance of galaxies changes across billions of light-years of space—and billions of years in time. Observations from NASA's James Webb Space Telescope will compliment those from Hubble and extend them to the earliest galaxies in the universe. Cr
